the codings work well without the combobox and the data are dsiplayed in the console tab.
I want to make it easier by choosing data from combobox rather than enter input.
So, how do i display the selected item from the combobox?

You need to get the "selected item" from the combobox.
Then you can update your label, text area, or whatever else with the data it grabbed from your combobox.
JComboBox cb = (JComboBox)e.getSource();
String myName = (String)cb.getSelectedItem();
updateLabel(myName);
Note the cb.getSelectedItem(). That's what's actually grabbing the data from the combobox.
And here's a good resource with some more info about using Java comboboxes: https://docs.oracle.com/javase/tutorial/uiswing/components/combobox.html

Why wont my JOptionPane error message pop up?

I made a GUI program where it counts certain elements of whatever is entered in the main text field. If the text field is empty, a message should pop up saying that the user should enter text in the text field. I made an if statement if tfMain == null, a JOptionPane message should pop-up, but for some reason it won't. Any tips on why it doesn't pop up?
here is my code:
import java.awt.*;

public class LabExcer9 extends WindowAdapter implements ActionListener

To compare string please use equals or equalsIgnoreCase.
Replace your
if(tfMain.getText() == "" || tfMain.getText() == null )
statement with the following:
if("".equals(tfMain.getText())){
}

Swing frame doesnt hold or stay after clicking jbutton

I have 2 text areas with a button in between them in a frame in swing and I am using netbeans.
Clicking the button picks up an sql query from textArea1, using getText().
The input is processed (i.e. checked the spellings of the keywords after splitting the query) with SubmitData(). Inside that method, it only uses setText() to set the output to textArea2.
My Problem Is:
The frame just doesn't stay or hold after I press the button.
Here is my code:
void createUI() throws Exception
{
JFrame frame = new JFrame("JDBC All in One");
// Layout of Main Window
Container c = frame.getContentPane();
c.setLayout(new BoxLayout(c, BoxLayout.Y_AXIS));
textArea1 = new JTextArea(10, 50);
textArea1.setBounds(10, 10, 30, 30);
btnInsert = new JButton("Submit");
btnInsert.setBounds(10, 10, 10, 10);
btnInsert.addActionListener(this);
textArea2 = new JTextArea(10, 50);
textArea2.setBounds(10, 10, 30, 30);
JPanel pnlInput1 = new JPanel();
JPanel pnlInput2 = new JPanel();
JPanel pnlInput3 = new JPanel();
pnlInput1.add(textArea1);
pnlInput3.add(btnInsert);
pnlInput2.add(textArea2);
frame.add(pnlInput1);
frame.add(pnlInput3);
frame.add(pnlInput2);
frame.setSize(400, 500);
frame.pack();
frame.setVisible(true);
}
public void actionPerformed(ActionEvent evt)
{
String cmd = evt.getActionCommand();
if (cmd.equals("Submit")) {
try {
SubmitData();
} catch (Exception e) {}
}
}
public static void SubmitData() throws Exception {
s1 = textArea1.getText();
String[] s2 = s1.split("\\s+");
for (int i = 0; i < s2.length; i++) {
if (s2[i] .equals("elect")|| s2[i] .equals("selct") || s2[i].equals("slect" )|| s2[i].equals("selec")|| s2[i].equals("seect")
{
textArea2.setText("use 'select' instead of " + s2[i]);
System.exit(0);
}
if (s2[i] == "updat" || s2[i] == "updae" || s2[i] == "updte" || s2[i] == "upate") {
textArea2.setText("use 'update' instead of " + s2[i]);
System.exit(0);
}
if (s2[i] == "delet" || s2[i] == "delte" || s2[i] == "elete" || s2[i] == "dlete") {
textArea2.setText("use 'delete' instead of " + s2[i]);
System.exit(0);
}
if (s2[i] == "fro" || s2[i] == "frm" || s2[i] == "fom") {
textArea2.setText("use 'from' instead of " + s2[i]);
System.exit(0);
}
}
}
Edited-i've changed "==" fro string comparision with .equals() but the problem doesnt seem to go away.

System.exit(0);terminates your JVM. Remove it if you want to keep your frame.
Edit for second question :
After your first if, replace your if by else if in order that the others if don't execute when a condition is true.
for (int i = 0; i < s2.length; i++) {
if (s2[i] .equals("elect")|| s2[i] .equals("selct") || s2[i].equals("slect" )|| s2[i].equals("selec")|| s2[i].equals("seect")
{
textArea2.setText("use 'select' instead of " + s2[i]);
}
else if (s2[i] == "updat" || s2[i] == "updae" || s2[i] == "updte" || s2[i] == "upate") {
textArea2.setText("use 'update' instead of " + s2[i]);
}
else if (s2[i] == "delet" || s2[i] == "delte" || s2[i] == "elete" || s2[i] == "dlete") {
textArea2.setText("use 'delete' instead of " + s2[i]);
}
else if (s2[i] == "fro" || s2[i] == "frm" || s2[i] == "fom") {
textArea2.setText("use 'from' instead of " + s2[i]);
}

Tic Tac Toe game in Java

Ok guys...I'm stumped again.
I managed to get the game working. However, now I'm down to the point of trying to code the win conditions. I'm thinking of using a boolean array for each of the buttons, but can't figure out how to cross reference the buttons[] to the gameSquares[] to set the elements of gameSquares[] to true/false flags.
Any pointers? (Code is copied below).
** A few other interesting bugs I feel worth mentioning:
1) Start and Reset don't seem to work correctly
2) When the computer tries multiple attempts in invalid squares, the squares seem to jump or dance around. It's really weird.

usage of variables in different classes in Java

I don't understand the int a; in the main that I called st in the Action listener. I want the st to decrease for 1 everytime a cetain button is clicked but it seems to work separetly for each button. I made it so it writes it out on a button each time I press another button to test it and it only works for the first button and then it just stays the same. (I hope I'm making any sense)
Here is my code, Main class:
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.GridLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class Start {
public static int a;
public static JButton[][] gumbi = new JButton[15][15];
public static void main(String[] args) {
JFrame okno = new JFrame("Nonogram");
okno.setVisible(true);
okno.setSize(700, 700);
okno.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel(new BorderLayout());
okno.add(panel);
JPanel polje = new JPanel(new GridLayout(15, 15));
panel.add(polje, BorderLayout.CENTER);
a = 0;
for (int i = 0; i < 15; i++) {
for (int j = 0; j < 15; j++) {
if (i < 5 && j < 5) {
gumbi[i][j] = new JButton();
gumbi[i][j].setBackground(Color.GREEN);
// gumbi[i][j].addActionListener(new Listener(gumbi));
polje.add(gumbi[i][j]);
} else if (i < 5 || j < 5) {
gumbi[i][j] = new JButton();
gumbi[i][j].setBackground(Color.YELLOW);
// gumbi[i][j].addActionListener(new Listener(gumbi));
polje.add(gumbi[i][j]);
gumbi[i][j].setEnabled(false);
} else {
if (Math.random() <= 0.6) {
gumbi[i][j] = new JButton();
gumbi[i][j].setBackground(Color.WHITE);
gumbi[i][j].addActionListener(new Listener(gumbi));
gumbi[i][j].setText("3");
polje.add(gumbi[i][j]);
} else {
gumbi[i][j] = new JButton();
gumbi[i][j].setBackground(Color.WHITE);
gumbi[i][j].addActionListener(new Listener(gumbi));
gumbi[i][j].setText("4");
polje.add(gumbi[i][j]);
}
}
if (gumbi[i][j].getText() == "3") {
a += 1;
}
if (i == 14 && j == 14) {
gumbi[i][j].setText("" + a);
}
}
}
}
}
and ActionListener:
import java.awt.Color;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
public class Listener implements ActionListener {
JButton[][] gumbi = Start.gumbi;
int st = Start.a;
public Listener(JButton[][] gumbi) {
this.gumbi = gumbi;
}
public void actionPerformed(ActionEvent e){
JButton gumb = (JButton) e.getSource();
if( gumb.getBackground() == Color.WHITE){
gumb.setBackground(Color.BLACK);
} else if (gumb.getBackground() == Color.BLACK){
gumb.setBackground(Color.WHITE);
}
if( gumb.getBackground() == Color.WHITE && gumb.getText() == "3"){
st -= 1;
} else if (gumb.getBackground() == Color.BLACK && gumb.getText() == "3"){
st += 1;
gumbi[0][0].setText("" + st);
}
}
}

The problem is that you created a copy of the Static Variable(Start.a) to the instance variable (st), which will be individual copy for each instance of action listener.
If you really need to maintain the value at class level , why not manipulate the value directly rather keeping a copy.
if( gumb.getBackground() == Color.WHITE && gumb.getText() == "3"){
Start.a -= 1;
} else if (gumb.getBackground() == Color.BLACK && gumb.getText() == "3"){
Start.a += 1;
gumbi[0][0].setText("" + st);
}

Your line
int st = Start.a;
isn't doing what you think. It's reading the value of a when the instance is created, and copying its value into a new variable st. Changing st won't have any effect on a because you're only changing a copy; and you've got a new copy for each instance that you create.
Try changing Start.a directly, rather than copying it into a new st and changing that.

Java applet buttons are not displayed until i hover the mouse over them

So My problem is that the applet lunches with nothing in it as soon as i hover the mouse
on top of the buttons it displays them and works perfectly afterwards. I think there might be something wrong with paint but i am not sure. I tried several changes but noting seems to work.
Any help will be much appreciated.

When i run this applet using eclipse, it runs fine and i can see 2 buttons. Have you tried validating the applet after everything is ready?
this.validate();
this.repaint();
from Container.class:
The validate method is used to cause a container to lay out its subcomponents again. It should be invoked when this container's subcomponents are modified (added to or removed from the container, or layout-related information changed) after the container has been displayed.

I took sometime to modify the code of yours and I removed the paint() method and its working, now the screen display's without any freezing and all the components are displayed. Here's one important information for you which i found regarding paint() method when you extend JApplet.
Note: Move the logic which you had in your paint() method according to your design.
However, JApplets have a lot of extra structure that plain Applets
don't have. Because of this structure, the painting of a JApplet is a
more complex affair and is handled by the system. So, when you make a
subclass of JApplet you should not write a paint() method for it. As
we will see, if you want to draw on a JApplet, you should add a
component to the applet to be used for that purpose. On the other
hand, you can and generally should write an init() method for a
subclass of JApplet.
Below is the modified code, Hope it helps!!!
