A good way would be to create an array that hold the values chosen. Each time a
value is picked, have the box's value be set to the next value in the array.
You could then set up two more variables, one for each candidate. Within a for
loop you could step through the array and check each value. For each
value,increment the appropriate variable by one like this: candidate++.


Can someone please tell me how I would code  counters in this code?


import java.awt.*;

import java.awt.event.*;

import javax.swing.*;

public class  vote {

public static  void main(String[] args) {

JFrame f = new JFrame(" PRESIDENTIAL POLL: Today, I vote for");

f.setSize(600, 200);

f.setLocation(300, 200);

f.addWindowListener(new WindowAdapter( ) {

public void  windowClosing(WindowEvent we) { System.exit(0); }

});

JPanel entreePanel = new JPanel( );

final ButtonGroup entreeGroup = new ButtonGroup( );

JRadioButton radioButton;

entreePanel.add(radioButton = new JRadioButton("John Kerry"));

radioButton.setActionCommand("John Kerry");

entreeGroup.add(radioButton);

entreePanel.add(radioButton = new JRadioButton("George Bush"));

radioButton.setActionCommand("George Bush");

entreeGroup.add(radioButton);

entreePanel.add(radioButton = new JRadioButton("neither", true));

radioButton.setActionCommand("neither");

entreeGroup.add(radioButton);

final JPanel condimentsPanel = new JPanel( );

condimentsPanel.add(new JCheckBox("I am registered to vote"));

//condimentsPanel.add(new JCheckBox("Mustard"));

//condimentsPanel.add(new JCheckBox("Pickles"));

JPanel orderPanel = new JPanel( );

JButton orderButton = new JButton("Submit Vote");

orderPanel.add(orderButton);

Container content = f.getContentPane( );

content.setLayout(new GridLayout(3, 1));

content.add(entreePanel);

content.add(condimentsPanel);

content.add(orderPanel);

orderButton.addActionListener(new ActionListener( ) {

public void actionPerformed(ActionEvent ae) {

String entree =

entreeGroup.getSelection().getActionCommand( );

System.out.println("I cast my vote for " + entree + ".");

Component[] components = condimentsPanel.getComponents( );

for (int i = 0; i < components.length; i++) {

JCheckBox cb = (JCheckBox)components[i];

if (cb.isSelected( ))

System.out.println("" + cb.getText( ) + ".");

}

}

});

f.setVisible(true);

}

}
