Java Swing: Change JButton to an image button - java

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.

Issue in Radio Button Action Listener

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:
public class Emp4 {

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?

Updating Jlabel text from another class

I am trying to update the text of a Jlabel from another class. I tried using the setText method, which results in the program compiling fine, and running, however when I press the button nothing happens.
Here is the code from my Menu.class, where the Jlabel resides.
public class Menu extends JFrame {
private JPanel contentPane;
private JLabel lblOthello;
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
Menu frame = new Menu();
frame.setVisible(true);
}
});
}
public Menu() {
//Sets program icon
ImageIcon img = new ImageIcon("icon.png");
//Creates the frame
setForeground(Color.RED);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(100, 100, 384, 475);
contentPane = new JPanel();
contentPane.setBackground(Color.BLACK);
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
setContentPane(contentPane);
contentPane.setLayout(null);
lblOthello = new JLabel("Othello");
lblOthello.setForeground(Color.YELLOW);
lblOthello.setFont(new Font("Franklin Gothic Medium Cond", Font.BOLD, 33));
lblOthello.setHorizontalAlignment(SwingConstants.CENTER);
lblOthello.setBounds(0, 0, 366, 59);
contentPane.add(lblOthello);
JButton btnNewButton = new JButton("New Singleplayer Game");
btnNewButton.setForeground(Color.BLACK);
btnNewButton.setBackground(UIManager.getColor("Button.background"));
btnNewButton.setBounds(10, 72, 344, 45);
btnNewButton.addActionListener(new ButtonListener());
contentPane.add(btnNewButton);
JButton btnNewMultiplayerGame = new JButton("New Dualplayer Game");
btnNewMultiplayerGame.setBounds(10, 130, 344, 45);
btnNewMultiplayerGame.addActionListener(new ButtonListener());
contentPane.add(btnNewMultiplayerGame);
JSeparator separator = new JSeparator();
separator.setBounds(0, 57, 366, 2);
contentPane.add(separator);
JButton btnNewNetworkGame = new JButton("New Network Game");
btnNewNetworkGame.setBounds(10, 188, 344, 45);
btnNewNetworkGame.addActionListener(new ButtonListener());
contentPane.add(btnNewNetworkGame);
JButton btnAbout = new JButton("AI vs AI Game");
btnAbout.setBounds(10, 246, 344, 45);
btnAbout.addActionListener(new ButtonListener());
contentPane.add(btnAbout);
JButton btnNewButton_1 = new JButton("QUIT");
btnNewButton_1.setBounds(10, 446, 344, 25);
btnNewButton_1.addActionListener(new ButtonListener());
contentPane.add(btnNewButton_1);
JLabel lblNewLabel = new JLabel("New label");
lblNewLabel.setIcon(new ImageIcon("C:\\Users\\User\\workspace\\Othello\\src\\Othello.jpg"));
lblNewLabel.setBounds(0, -36, 366, 507);
contentPane.add(lblNewLabel);
JButton button = new JButton("QUIT");
button.setBounds(10, 390, 344, 25);
button.addActionListener(new ButtonListener());
contentPane.add(button);
JSeparator separator_1 = new JSeparator();
separator_1.setBounds(0, 375, 366, 2);
contentPane.add(separator_1);
}
public void setText(String text) {
lblOthello.setText(text);
System.out.println("executed");
contentPane.validate();
contentPane.repaint();
}
}
And here is the part of the code that executes the settext method from my buttonlistener class
case PLAYER_VS_AI:
Menu men = new Menu();
men.setText("Now");
men.revalidate();
men.repaint();
break;
Can anyone tell me why this doesn't work?

You are creating a new Menu object whenever the button is pressed instead of modifying the already existing Menu object.

Java Swing open existing form

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");

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");

}
}
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);
}
}

}

{
System.exit(0);
}
}
}

You button is defined twice, once as a local variable and once as an instance variable
JButton regMaterijalaButt = new JButton("Registar materijala");
Above is where you are defining the button as a local variable
if(event.getSource() == regMaterijalaButt )
Your ActionListener is referencing the instance variable.
Your code should be:
//JButton regMaterijalaButt = new JButton("Registar materijala");
regMaterijalaButt = new JButton("Registar materijala");

In your ActionListener for that button retrieve the text of the textfield using textfield.getText() and then use this value to query database. I'm assuming that you know well how to query database.

Wait! you haven't implemented ActionListener!
Do the following:
but_per.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent ae) {
/// write your code here!
String a= field.getText();
System.out.print(a);
///or DB code
}
});
Here is a LINK if you aren't familiar with Action Listener
UPDATE:
If you want all processing after a key press, you have to implement keybord events,
you can find a tutorial link here

This source is the closest workable version of your code I could produce, but it still has many serious problems.
Using the start() method incorrectly. The method will be called each time the browser is restored from minimized.
Use of a null layout and setBounds().
A free floating, non modal GUI element will cause focus problems..
Having said that, type a number in the employee code field and hit enter to see something like (screenshot shortened vertically)..
