JavaSwing add multiple JTable to JFrame

I am working on java swing application.I have to browse multiple CSV data files and display them into JFrame using JTable.I am trying to add multiple(non static) JTable into JFrame.All (N) JTable i want to include inside a JSrollPane.At this moment i can display only 1 table to JScrollPane.
Thanks in advance!
if (e.getSource() == jbtreadbrowsefile) {
try {
for(int k=0;k<file_locations.length;k++) {
String currentLocation=file_locations[k];
inputList = new ArrayList();
File inputF = new File(currentLocation);
InputStream inputFS = new FileInputStream(inputF);
BufferedReader br = new BufferedReader(new InputStreamReader(inputFS));
inputList = br.lines().collect(Collectors.toList());
br.close();
int count = inputList.size();
if(count>0)
{
data = new String[count - 1][8];
for (int i = 0; i < count - 1; i++) {
String[] arrOfStr = inputList.get(i + 1).toString().split(",");
String test1= arrOfStr[0];
String test2= arrOfStr[1];
String test3= arrOfStr[2];
String test4 = arrOfStr[3];
String test5= arrOfStr[4];
String test6= arrOfStr[5];
String test7= arrOfStr[6];
data[i][0] = "" + (i + 1);
data[i][1] = test1;
data[i][2] = test2;
data[i][3] = test3;
data[i][4] = test4;
data[i][5] = test5;
data[i][6] = test6;
data[i][7] = test7;
}
j = new JTable(data, columnNames);
TableColumnModel tcm = j.getColumnModel();
tcm.getColumn(0).setPreferredWidth(40);
tcm.getColumn(1).setPreferredWidth(220);
tcm.getColumn(2).setPreferredWidth(120);
tcm.getColumn(3).setPreferredWidth(80);
tcm.getColumn(4).setPreferredWidth(80);
tcm.getColumn(5).setPreferredWidth(80);

DefaultTableCellRenderer centerRenderer = new DefaultTableCellRenderer();
centerRenderer.setHorizontalAlignment(JLabel.CENTER);

for (int i = 0; i < j.getRowCount(); i++) {
j.setRowHeight(i, 20);
}
j.getTableHeader().setFont(new Font("SansSerif", Font.BOLD, 15));
j.getTableHeader().setReorderingAllowed(false);
j.repaint();
JScrollPane sp = new JScrollPane(j);
sp.setBounds(10, 200, 780, 440);
add(sp);

JScrollPane sp = new JScrollPane(j);
sp.setBounds(10, 200, 780, 440);
add(sp);
Don't use setBounds(). It is the job of the layout manager to determine the size/location of a component.
At this moment i can display only 1 table to JScrollPane.
Correct. A JScrollPane is designed to display a single JTable. The header of the JTable will be displayed at the header view of the scroll pane and the table will be displayed in the center of the scroll pane. You may then also see scrollbars in the scroll pane depending on the data in the table.
If you want to "merge" data from multiple files into the same table, then you need to update the TableModel with the data from each file instead of creating a new table each time.
You can dynamically add data to the model by using the addRow(…) method of the DefaultTableModel.

For displaying each JTable into JFrame,i added all JTable into a JPanel and added this JPanel into JScrollPane.After displaying each JTable the problem was that we can not display each JTable header.I added to another JPanel each JTable header and it's shows up.
if (e.getSource() == jbtreadbrowsefile) {
GridLayout grid = new GridLayout(0, 1, 30, 20);
jpaneltable=new JPanel(grid);
try {
for(int k=0;k<file_locations.length;k++) {
String currentLocation=file_locations[k];
inputList = new ArrayList();
File inputF = new File(currentLocation);
InputStream inputFS = new FileInputStream(inputF);
BufferedReader br = new BufferedReader(new InputStreamReader(inputFS));
inputList = br.lines().collect(Collectors.toList());
br.close();
int count = inputList.size();
if(count>0)
{
data = new String[count - 1][8];
for (int i = 0; i < count - 1; i++) {
String[] arrOfStr = inputList.get(i + 1).toString().split(",");
String test1= arrOfStr[0];
String test2= arrOfStr[1];
String test3= arrOfStr[2];
String test4= arrOfStr[3];
String test5= arrOfStr[4];
String test6= arrOfStr[5];
String test7= arrOfStr[6];
data[i][0] = "" + (i + 1);
data[i][1] = test1;
data[i][2] = test2;
data[i][3] = test3;
data[i][4] = test4;
data[i][5] = test5;
data[i][6] = test6;

centerRenderer.setHorizontalAlignment(JLabel.CENTER);
j.getColumnModel().getColumn(0).setCellRenderer(centerRenderer);
for (int i = 0; i < j.getRowCount(); i++) {
j.setRowHeight(i, 20);
}
j.getTableHeader().setFont(new Font("SansSerif", Font.BOLD, 15));
j.getTableHeader().setReorderingAllowed(false);
j.getTableHeader().setPreferredSize(new Dimension(0,HEADER_HEIGHT));
j.repaint();
jpaneltable.add(j.getTableHeader(),BorderLayout.NORTH);
jpaneltable.add(j, BorderLayout.CENTER);

}
JScrollPane sp = new JScrollPane(jpaneltable,JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);
sp.setBounds(10, 200, 780, 440);
add(sp);
}

Why doesn't my find method work here even with all the values saved on the array?

I am fairly new to programming and I cant seem to find the problem in the area where I make the program search for the specific key term tho it's saved in the array.
here is the code where I add the details of the customer:
private void addCustomerToSeat(String[] seatBooking, String[] customerName, String[] seatBookingAndCustomerName) {
Button[] seat = new Button[(SEATING_CAPACITY + 1)];
Button selectSeat = new Button(" Click to Book Seats ");
selectSeat.setLayoutX(320);
selectSeat.setLayoutY(512);
selectSeat.setOnAction(event -> {
window.setScene(scene2);
});
Label header = new Label("TRAIN BOOKING SYSTEM");

header.setStyle("-fx-font-size: 25px;");
Label clientName = new Label("Enter Customer Name: ");
clientName.setLayoutX(225);
clientName.setLayoutY(150);
clientName.setStyle("-fx-font-size: 16px;");
TextField cusName = new TextField();
cusName.setLayoutX(397);
cusName.setLayoutY(150);
Label destination = new Label("Choose destination: ");
destination.setLayoutX(225);
destination.setLayoutY(200);
destination.setStyle("-fx-font-size:16px;");
String [] destinations = {"Colombo to Badulla", "Badulla to Colombo"};
ComboBox Destination = new ComboBox(FXCollections.observableArrayList(destinations));
Destination.setLayoutX(397);

datePicker.setValue(now);
datePicker.setLayoutX(397);
datePicker.setLayoutY(275);
AnchorPane layout1 = new AnchorPane();
layout1.setStyle("-fx-background-color:#5a89a3; ");
layout1.getChildren().addAll(Destination,destination,selectSeat,clientName,cusName,header,date,datePicker);

window.setScene(scene1);
window.show();

Button submit = new Button("Submit");
submit.setLayoutX(640);
submit.setLayoutY(480);
Button exit = new Button("Exit");
exit.setLayoutX(710);
exit.setLayoutY(480);
exit.setOnAction(event -> {
window.close();
displayMenu(seatBooking,customerName,seatBookingAndCustomerName);
});
Label greenSeat = new Label("Unbooked Seat");
greenSeat.setLayoutY(160);

Button booked = new Button(" ");
booked.setLayoutX(560);
booked.setLayoutY(200);
booked.setStyle("-fx-background-color:red;");
GridPane gridPane = new GridPane();
int columnIndex = 0;
int rowIndex = 0;
int rowIndexes = 0;
int[] reservedSeats = new int[1];
String seatNumber;
for (int i = 1; i < (SEATING_CAPACITY + 1); i++) {
if (i <= 9) {
seatNumber = "0" + (i);
} else {
seatNumber = "" + (i);
}
seat[i] = new Button(seatNumber);
gridPane.add(seat[i], columnIndex, rowIndex);
columnIndex++;
rowIndexes++;
if (rowIndexes == 4) {
columnIndex = 0;

}
}
for (int f = 1; f < (SEATING_CAPACITY + 1); f++) {
if (seatBooking[f].equals("Empty")) {
seat[f].setStyle("-fx-background-color: green;");
}
if (seatBooking[f].equals("booked")) {
seat[f].setStyle("-fx-background-color: red");
}
}
List<Integer> bookedCurrent = new ArrayList<>();
for (int f = 1; f < (SEATING_CAPACITY + 1); f++) {
int finalF = f;
seat[f].setOnAction(event -> {
seat[finalF].setStyle("-fx-background-color: red");
seatBooking[finalF] = "booked";
bookedCurrent.add(finalF);
});
submit.setOnAction(event -> {
String personName = cusName.getText();
personName = personName.toLowerCase();
window.close();
for ( int loopSeatArray = 1; loopSeatArray< (SEATING_CAPACITY + 1); loopSeatArray++) {
if (loopSeatArray == reservedSeats[0]) {
seatBooking[loopSeatArray] = "Booked";
customerName[loopSeatArray] = personName;
}
seatBookingAndCustomerName[loopSeatArray] = seatBooking[loopSeatArray];
}
for (int total = 43; total < (SEATING_CAPACITY + 1); total++){
seatBookingAndCustomerName[total]= customerName[total-42]; }
displayMenu(seatBooking, customerName, seatBookingAndCustomerName);
});
}
gridPane.setLayoutX(160);
gridPane.setLayoutY(80);
gridPane.setHgap(20);
gridPane.setVgap(5);
AnchorPane layout2 = new AnchorPane();
layout2.setStyle("-fx-background-color:#5a89a3; ");
layout2.getChildren().addAll(gridPane,submit,exit,header1,greenSeat,unbooked,redSeat,booked);
scene2 = new Scene(layout2,800,600);
window.setTitle("Train Booking System");
window.show();
window.setOnCloseRequest(event -> {
window.close();
displayMenu(seatBooking,customerName,seatBookingAndCustomerName);
});
}
and here is the part of the code where I prompt the user for the name and find the location of given name:
private void findCustomerSeats(String[] seatBooking, String[] customerName, String[] seatBookingAndCustomerName) {
Scanner input = new Scanner(System.in);
System.out.println("Please enter customer name: ");
String name = input.nextLine();
boolean flag = false;
for (int i = 1; i < (SEATING_CAPACITY + 1); i++){
if (name.toLowerCase().equals(customerName[i])){
System.out.println("Seats booked are: " + seatBooking);
flag = true;
}
}
if (flag !=true){
System.out.println(name + " has not reserved a seat");
}
displayMenu(seatBooking,customerName,seatBookingAndCustomerName);
}
when the above code is run, and when I input the name, it plain out does not work.

One potential issue, your for loop is starting at index 1, I would begin by using something like this:
for (int idx = 0; idx < customerName.length; idx++) {
//This way you will not check an index of your array that does not exist
//which could cause a NullPointerException
//Additionally, this is useful if you want to grow your customerName array
}
Another useful tip, that I use all the time. Try printing out more information and see if you can spot the issue. This might seem trivial but I have found it extremely helpful. For example:
System.out.println("Inputted Name: " + name);
for (int idx = 0; idx < customerName.length; idx++) {
System.out.println("Does " + name.toLowerCase() + " = " + customerName[idx] + " ?");
}

How to use JButton in Java

I'm trying to create a hangman game using the Swing class and Graphics class for a APCS class I have.
I created a JButton that would take the guess typed in by the user and either add it to the "misses" or fill in all of the corresponding letters in the word. I have a separate txt file where I pick a random word from.
When I run the program, all of the components show up, but the button does not do anything. I have been working on this for a few days and don't know what I am doing wrong. I have only learnt how to use the Swing class recently, so it may be a stupid mistake for all I know. I have put all of the code down below.
public class Hangman extends JFrame {
DrawPanel panel = new DrawPanel();
Graphics g = panel.getGraphics();
JTextField guess;
JTextField outputWord;
JTextField missesString;
boolean play;
JButton button = new JButton();
String output = "";
String word;
int misses = 0;
public Hangman() {
int again = 0;
String[] dictionary = new String[1000];
In words = new In("words.txt");
JFrame app = new JFrame();
app.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
app.setVisible(true);
app.setSize(500, 500);
for (int i = 0; i < 1000; i++) {
dictionary[i] = words.readLine();
}
do {
int num = (int) (Math.random() * 1000);
word = dictionary[num].toLowerCase();
String answer = word;
word = "";
for (int i = answer.length(); i > 0; i--) {
word = word + "*";
}
int length = answer.length();
app.setLayout(new BorderLayout());
JLabel letter = new JLabel();
letter.setFont(new Font("Arial", Font.BOLD, 20));
letter.setText("Enter Your guess");
guess = new JTextField(10);
JLabel output = new JLabel();
output.setFont(new Font("Arial", Font.BOLD, 20));
output.setText("The Word is");
outputWord = new JTextField(30);
outputWord.setText(word);
outputWord.setEditable(false);
JLabel misses = new JLabel();
misses.setFont(new Font("Arial", Font.BOLD, 20));
misses.setText("Misses:");
missesString = new JTextField(52);
missesString.setEditable(false);
button = new JButton("Guess");
button.addActionListener(new ButtonListener());
JPanel panels = new JPanel();
panels.setLayout(new BorderLayout());
JPanel panel1 = new JPanel();
panel1.add(letter);
panel1.add(guess);
panel1.add(button);
JPanel panel2 = new JPanel();
panel2.add(output);
panel2.add(outputWord);
JPanel panel3 = new JPanel();
panel3.add(misses);
panel3.add(missesString);
app.add(panel1, BorderLayout.NORTH);
app.add(panel2, BorderLayout.EAST);
app.add(panel3, BorderLayout.SOUTH);
app.add(panels);
app.setVisible(true);
again = JOptionPane.showConfirmDialog(null, "Do you want to play again?");
} while (again == JOptionPane.YES_OPTION);
}
private class ButtonListener implements ActionListener {
public void actionPerformed(ActionEvent e) {
if (e.getSource() == guess) {
output = "";
}
for (int i = 0; i <= word.length() - 1; i++) {
if (guess.getText().equalsIgnoreCase(word.substring(i, i + 1))) {
output = output.substring(0, i) + guess + output.substring(i + 1, word.length() - 1);
outputWord.setText(output);
} else {
misses++;
missesString.setText(missesString.getText() + guess + " ");
}
}
}
}
}
The components show up perfectly on the screen, it is only the button that is giving me a hard time by not working as expected.

WARNING Possible use of "Transverse_Mercator" projection outside its valid area

I am trying to combign tiff image and shapefile and want show it. For this, I am using GeoTiff and I am stuck that my tiff file is now being displayed. Shapefile is showing properly but tiff image, which is having only 1 band and grey scale index, is not being shown because of some reason. I am getting one warning message as below.

this.setBorderShape(new File("E:/shapefilename.shp"));
try {
this.displayLayers();
} catch (Exception e) {
e.printStackTrace();
}
}
This is how i use this class in main class
//see output in main method
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
MapImagePanel panel = new MapImagePanel();
panel.setPreferredSize(new Dimension(1024,768));
panel.setVisible(true);
frame.getContentPane().add(panel);
frame.pack();
frame.setVisible(true);
frame.show();

TLDR; add the following line to your program start up:
System.setProperty("org.geotools.referencing.forceXY", "true");
From GeoTools FAQ as computer programmers they knew that coordinates would be expressed as longitude,latitude pairs so they could use existing graphics code easily by treating them as a simple (x,y) pair. but for sequence like (x,y) or (y,x) they confused that is why this error is coming.

Scroll a JScrollPane to a specific row on a JTable [duplicate]

This question already has answers here:
Closed 11 years ago.

JTable Scrolling to a specified row index
I have a JTable and I programmatically need to select a row by using this code:
myTable.setRowSelectionInterval(i, j);
(where i and j are valid row and column numbers respectively).
The problem is, when you jump to a row, the JScrollPane does not move.
In this case, the table is quite long, and often the "selected row" is not visible on the screen, so the user has to stay scrolling up/down manually to find it. I would like to know how I can make the JScrollPane automatically jump to the specific location of the row.
Edit: Found this one liner which can do it:
table.scrollRectToVisible(table.getCellRect(row,0, true));

int row = table.getSelectedRow();
String rowKey = table.getValueAt(row, table.convertColumnIndexToView(0)).toString();
for (JTable t : tables) {
if (t == table) {
continue;
}
changeSelection(t, rowKey);
JViewport viewport = (JViewport) t.getParent();
Rectangle rect = t.getCellRect(t.getSelectedRow(), 0, true);
Rectangle r2 = viewport.getVisibleRect();
t.scrollRectToVisible(new Rectangle(rect.x, rect.y, (int) r2.getWidth(), (int) r2.getHeight()));
System.out.println(new Rectangle(viewport.getExtentSize()).contains(rect));
}
} finally {
ignore = false;
}
}
public static void main(String[] args) {
TableSelectionGood tableSelection = new TableSelectionGood();
}
}

I used this in my old project:
public static void scrollToVisible(JTable table, int rowIndex, int vColIndex)
{
if (!(table.getParent() instanceof JViewport)) return;
JViewport viewport = (JViewport)table.getParent();
Rectangle rect = table.getCellRect(rowIndex, vColIndex, true);
Point pt = viewport.getViewPosition();
rect.setLocation(rect.x-pt.x, rect.y-pt.y);
viewport.scrollRectToVisible(rect);
}
