I have written some code when one of the option in radio button is clicked
it should display one jlabel and jtext field. And when other option in the radio button is clicked it should hide the previous shown jlabel and jtext field and display new jlabel and jtext field.
In the output when I click on one of the radio button it is displaying nothing unless and until I maximize my Window. After geting my jlabel and jtextfield If I click on other radio button the jlabel and jtextfield is hidden but Im not able to see new jlabel and jtextfield for that radiobutton.
enter code here

Insteed of adding and removing components, simply add all and hide/show them on radiobox selection like this:
panel_1.add(jlblEmpSal);
panel_1.add(jtxtSal);
panel_1.add(jlblEmpHour);
panel_1.add(jtxtHour_Pay);
panel_1.add(jlblEmpWork);
panel_1.add(jtxtHour_Worked);
ActionListener myAction = new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
jlblEmpHour.setVisible(jrdbtnContract.isSelected());
jtxtHour_Pay.setVisible(jrdbtnContract.isSelected());
jtxtHour_Worked.setVisible(jrdbtnContract.isSelected());
jlblEmpWork.setVisible(jrdbtnContract.isSelected());
jlblEmpSal.setVisible(jrdbuttonFullTime.isSelected());
jtxtSal.setVisible(jrdbuttonFullTime.isSelected());
}
};
myAction.actionPerformed(null); // to initialize labels first
jrdbuttonFullTime.addActionListener(myAction); // add actionlisteners
jrdbtnContract.addActionListener(myAction);// add actionlisteners
As you can see, you dont even need 2 separate action listeners as one but shared instance is just enough.
So the complete app will look like this:

Your radio buttons start off both unchecked, so you see no salary detail initially. When you click one or the other, the corresponding details appear.
In which case(which radiobutton checked ?) you want to show which controls?

I have been trying this for hours. I want to change each of the JButton components to image buttons (They were radio buttons that's why the variable names don't make sense). The for loop inside is just displaying all the images under the button's. Each image is called Option1, Option2, etc. So what I have been trying to do is get rid of the for loop and just have 10 buttons with images on them that you can click.
If someone could help me figure that out that would be great. All I've been able to do is have the button created with an image but the button appears on a completely different window.

I know there must be an answer somewhere on this site but I cannot seem to find it.
Please also note that I am new at Java development
Create your own subclass of a JPanel which represents one "datasheet" or tablecell or what ever
public DataPanel extends JPanel{
private JTextField field1 = new JTextField();
private JTextField field2 = new JTextField();
// ..... and so on
public DataPanel(YourDataObject data){
field1.setText(data.getValue1());
field2.setText(data.getValue2());
// ... and so on
// then add all of your text fields to the panel
add(field1);
add(field2);
// .... and so on
}
}
Then on button click you add the panel to the component you want to show it on
onClick(SomeEvent event){
yourComponent.add(new DataPanel(yourDataObject));
}
i need to save texts from text boxes to text file but any code i found on or made it didn't work, any idea? like any at all? which code would work. i had to use java gui where my teacher teach us about java, but nothing about GUI so ii cant even make save to text file.

You can use basic file writing from Java. The only difference here from basic file writing is that you need to get the Strings to write from the text attributes of your objects. Here is one example from your code:
import java.io.PrintWriter;
try{
PrintWriter fileWriter = new PrintWriter("myFile.txt", "UTF-8");
fileWriter.println(textFieldDepartureAirport.selectAll());
fileWriter.close();
} catch (IOException e) {
e.printStackTrace();
}
Since your teacher did not include much about the UI items, you are able to look up the JavaDoc info about the object type that is holding the data. For example, your text boxes are declared as JTextField, so you can find more info about this class here:
https://docs.oracle.com/javase/7/docs/api/javax/swing/JTextField.html
I'm trying to call a method that opens a new existing frame, but all I get is an empty frame without content.
This is the code that calls the function when a button is preesed:
JButton btnPersonalInfo = new JButton("Personal Info");
btnPersonalInfo.setBounds(10, 5, 120, 23);
btnPersonalInfo.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
JFrame PersonalInfo = new JFrame("Personal Info");
PersonalInfo content = new PersonalInfo();
PersonalInfo.setContentPane(content);
PersonalInfo.setSize(700,700);
PersonalInfo.setLocation(100,15);
PersonalInfo.setDefaultCloseOperation( JFrame.HIDE_ON_CLOSE );
PersonalInfo.setResizable(false);
PersonalInfo.setVisible(true);
}
});
panel_1.add(btnPersonalInfo);
This is how I initialize the PersonalInfo function:
public PersonalInfo() {
initialize();
}
/**
* Initialize the contents of the frame.
*/
private void initialize() {
frame = new JFrame();
frame.setBounds(100, 100, 450, 300);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel();
frame.getContentPane().add(panel, BorderLayout.CENTER);
panel.setLayout(null);
JLabel lblPersonalInfo = new JLabel("Personal Information");
lblPersonalInfo.setFont(new Font("Arial", Font.BOLD, 16));
lblPersonalInfo.setBounds(110, 11, 185, 14);
panel.add(lblPersonalInfo);
JLabel lblFullName = new JLabel("Full Name");
lblFullName.setBounds(10, 36, 58, 14);
panel.add(lblFullName);
JLabel lblNationality = new JLabel("Nationality");
lblNationality.setBounds(10, 61, 78, 14);
panel.add(lblNationality);
JLabel lblDateBirth = new JLabel("Date of Birth");
lblDateBirth.setBounds(10, 86, 78, 14);
panel.add(lblDateBirth);
JLabel lblGender = new JLabel("Gender");
lblGender.setBounds(10, 111, 46, 14);
panel.add(lblGender);
JLabel lblAddress = new JLabel("Address");
lblAddress.setBounds(10, 164, 58, 14);
panel.add(lblAddress);
JLabel lblMobile = new JLabel("Mobile");
lblMobile.setBounds(10, 189, 46, 14);
panel.add(lblMobile);
JLabel lblEmail = new JLabel("E-mail");
lblEmail.setBounds(10, 214, 46, 14);
panel.add(lblEmail);
JRadioButton rdbtnM_2 = new JRadioButton("M");
rdbtnM_2.setBounds(74, 133, 109, 23);
panel.add(rdbtnM_2);
JRadioButton rdbtnF = new JRadioButton("F");
rdbtnF.setBounds(74, 107, 109, 23);
panel.add(rdbtnF);
}
}
Basically I'm expecting to view the frame from the PersonalInfo method when I press the btnPersonalInfo button and right now I only get an empty frame.
Thank you and sorry if this is a duplicate, but it's my first question here.
Remove frame = new JFrame(); from your initialize()
Simply:
JPanel panel = new JPanel();
add(panel, BorderLayout.CENTER);//It will be added to the ContentPane by default.
panel.setLayout(null);
...
Then when calling, remove the following block:
JFrame PersonalInfo = new JFrame("Personal Info");
PersonalInfo content = new PersonalInfo();
PersonalInfo.setContentPane(content);
Replace it by:
PersonalInfo personalInfo = new PersonalInfo();
personalInfo.setSize(700,700);
personalInfo.setLocation(100,15);
....
So this should be your method call:
public void actionPerformed(ActionEvent e) {
PersonalInfo personalInfo = new PersonalInfo();
personalInfo.setSize(700,700);
personalInfo.setLocation(100,15);
personalInfo.setDefaultCloseOperation( JFrame.HIDE_ON_CLOSE );
personalInfo.setResizable(false);
personalInfo.setVisible(true);
}
And this should be your Class:
public class PersonalInfo extends JFrame
{
public PersonalInfo() {
initialize();
}
/**
* Initialize the contents of the frame.
*/
private void initialize() {
JPanel panel = new JPanel();
add(panel, BorderLayout.CENTER);
panel.setLayout(null);
JLabel lblPersonalInfo = new JLabel("Personal Information");
lblPersonalInfo.setFont(new Font("Arial", Font.BOLD, 16));
lblPersonalInfo.setBounds(110, 11, 185, 14);
panel.add(lblPersonalInfo);
JLabel lblFullName = new JLabel("Full Name");
lblFullName.setBounds(10, 36, 58, 14);
panel.add(lblFullName);
JLabel lblNationality = new JLabel("Nationality");
lblNationality.setBounds(10, 61, 78, 14);
panel.add(lblNationality);
JLabel lblDateBirth = new JLabel("Date of Birth");
lblDateBirth.setBounds(10, 86, 78, 14);
panel.add(lblDateBirth);
JLabel lblGender = new JLabel("Gender");
lblGender.setBounds(10, 111, 46, 14);
panel.add(lblGender);
JLabel lblAddress = new JLabel("Address");
lblAddress.setBounds(10, 164, 58, 14);
panel.add(lblAddress);
JLabel lblMobile = new JLabel("Mobile");
lblMobile.setBounds(10, 189, 46, 14);
panel.add(lblMobile);
JLabel lblEmail = new JLabel("E-mail");
lblEmail.setBounds(10, 214, 46, 14);
panel.add(lblEmail);
JRadioButton rdbtnM_2 = new JRadioButton("M");
rdbtnM_2.setBounds(74, 133, 109, 23);
panel.add(rdbtnM_2);
JRadioButton rdbtnF = new JRadioButton("F");
rdbtnF.setBounds(74, 107, 109, 23);
panel.add(rdbtnF);
}
}
I have created this Automated Library. And I need to know how to connect my Database per each JFrame.
This is my main method:
package com.Student.GUI;
public class Student_HomePage extends JFrame {
private JPanel contentPane;
private JTextField searchBox;
private static String results[];
private static Connection conn;
private static String searchText;
/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
DBConnect db = new DBConnect();
conn = db.openConnection();
Student_HomePage frame = new Student_HomePage();
frame.setVisible(true);
frame.setBounds(400,150,599,489);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**
* Create the frame.
*/
public Student_HomePage() {
setBackground(Color.WHITE);
setIconImage(Toolkit.getDefaultToolkit().getImage("D:\\ITC302-Core Java\\java_workspace\\Pictures\\lala.png"));
setTitle("LookBook");
setResizable(false);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(100, 100, 599, 489);
contentPane = new JPanel();
contentPane.setBackground(Color.WHITE);
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
setContentPane(contentPane);
contentPane.setLayout(null);
JButton btnHome = new JButton("Home");
btnHome.setFont(new Font("Plantagenet Cherokee", Font.PLAIN, 16));
btnHome.setEnabled(false);
btnHome.setContentAreaFilled(false);
btnHome.setBorder(null);
btnHome.setBounds(144, 24, 95, 25);
contentPane.add(btnHome);
JButton btnAuthors = new JButton("Authors");
btnAuthors.setFont(new Font("Plantagenet Cherokee", Font.PLAIN, 16));
btnAuthors.setContentAreaFilled(false);
btnAuthors.setBorder(null);
btnAuthors.setBounds(241, 24, 95, 25);
contentPane.add(btnAuthors);
JButton btnBooks = new JButton("Books");
btnBooks.setFont(new Font("Plantagenet Cherokee", Font.PLAIN, 16));
btnBooks.setContentAreaFilled(false);
btnBooks.setBorder(null);
btnBooks.setBounds(338, 24, 95, 25);
contentPane.add(btnBooks);
JTextArea textArea = new JTextArea();
textArea.setText("|");
textArea.setFont(new Font("Monospaced", Font.PLAIN, 35));
textArea.setEditable(false);
textArea.setBounds(227, 11, 26, 57);
contentPane.add(textArea);
JTextArea textArea_1 = new JTextArea();
textArea_1.setText("|");
textArea_1.setFont(new Font("Monospaced", Font.PLAIN, 35));
textArea_1.setEditable(false);
textArea_1.setBounds(325, 11, 26, 57);
contentPane.add(textArea_1);
searchBox = new JTextField();
searchBox.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
String temp = new String(searchBox.getText());
searchText = temp;
}
});
searchBox.setColumns(10);
searchBox.setBounds(37, 210, 148, 25);
contentPane.add(searchBox);
JTextArea textArea_2 = new JTextArea();
textArea_2.setText("Search title of books,\r\nauthors or genre");
textArea_2.setFont(new Font("Plantagenet Cherokee", Font.PLAIN, 14));
textArea_2.setBounds(37, 248, 188, 40);
contentPane.add(textArea_2);
JButton btnSearch = new JButton("Search");
btnSearch.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
String temp = new String(searchBox.getText());
btnSearchActionPerformed(e, temp);
}
});
btnSearch.setIcon(new ImageIcon("D:\\ITC302-Core Java\\java_workspace\\Pictures\\searchIcon.png"));
btnSearch.setContentAreaFilled(false);
btnSearch.setBorder(null);
btnSearch.setBackground(Color.WHITE);
btnSearch.setBounds(185, 210, 87, 25);
contentPane.add(btnSearch);
JLabel label = new JLabel("");
label.setIcon(new ImageIcon("D:\\ITC302-Core Java\\java_workspace\\Pictures\\download.jpg"));
label.setHorizontalAlignment(SwingConstants.CENTER);
label.setBounds(270, 202, 290, 215);
contentPane.add(label);
JLabel bookIcon = new JLabel("");
bookIcon.setIcon(new ImageIcon("D:\\ITC302-Core Java\\java_workspace\\Pictures\\BookIcon.png"));
bookIcon.setBounds(101, 78, 116, 90);
contentPane.add(bookIcon);
JLabel lookBookIcon = new JLabel("");
lookBookIcon.setIcon(new ImageIcon("D:\\ITC302-Core Java\\java_workspace\\Pictures\\image.png"));
lookBookIcon.setBounds(213, 74, 290, 135);
contentPane.add(lookBookIcon);
}
public void btnSearchActionPerformed (ActionEvent e, String searchText) {
DBConnect db = new DBConnect();
results = db.selectMatchedData(searchText, conn);
//if (results.length != 0) {
this.dispose();
Student_SearchList window = new Student_SearchList();
window.setVisible(true);
//}
//else {
//Student_Warning window = new Student_Warning();
//window.setVisible(true);
//}
}
}
And this is where I want to connect my Database:
JButton btnSearch = new JButton("Search");
btnSearch.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
String temp = new String(searchBox.getText());
btnSearchActionPerformed(e, temp);
}
});
This whole code is my Main.java.
