    Default JFrame Question

    I am to make a mini game where the there are 10 boxes.. the user gets the first turn and asked to choose 1,2,or 3 boxes and click the complete button... then the computer is asked to choose 1,2,or 3 boxes and so on until the last player chooses the last box. That declares the winner.

    I have the user checking the boxes but when it comes to the computer doing it thats when i have trouble.

    please advise

    import java.awt.event.ActionListener;
    import javax.swing.JFrame;
    import java.awt.*;
    import javax.swing.*;
    import java.awt.event.*;
    /**
     */
    public class LastManStanding extends JFrame implements ActionListener{
     
    	 JCheckBox[] checkBoxes = new JCheckBox[10];
     
    	    JButton turn = new JButton("Complete Turn");   
    	    JLabel header = new JLabel ("Please select 1, 2, or 3 boxes.");   
    	    JLabel footer = new JLabel ("Whoever selects the last box wins.");   
    	    Font headerFont = new Font("Century", Font.PLAIN, 15);   
    	    Font footerFont = new Font("Century", Font.PLAIN, 13);   
     
    	    public LastManStanding()   
    	    {   
    	        final int FRAME_WIDTH = 240;   
    	        final int FRAME_HEIGHT = 200;   
    	        JFrame gameFrame = new JFrame("Last Man Standing");   
    	        gameFrame.setBounds(600,400,FRAME_WIDTH, FRAME_HEIGHT);   
    	        header.setFont(headerFont);   
    	        footer.setFont(footerFont);   
    	        // a loop to create and modify
    	        for (int i = 0; i < checkBoxes.length; i++)
    	        {
    	            checkBoxes[i] = new JCheckBox(String.valueOf(i + 1)); 
    	            checkBoxes[i].addActionListener(this);
    	        }
    	        turn.addActionListener(this);   
    	        gameFrame.setLayout(new FlowLayout());   
    	        gameFrame.add(header);   
    	        for (JCheckBox checkBox: checkBoxes) // for-each loop
    	        {
    	            gameFrame.add(checkBox);   
    	        }
    	        gameFrame.add(turn);   
    	        gameFrame.add(footer);   
    	        gameFrame.setVisible(true);   
    	        gameFrame.setSize(FRAME_WIDTH, FRAME_HEIGHT);   
    	    }   
     
    	    public static void main(String[] args)
    	    {   
    	        LastManStanding game = new LastManStanding();   
    	        System.out.println(game.getComponents());   
    	    }   
     
    	    public void actionPerformed(ActionEvent e)   
    	    {   
    	        Object source = e.getSource();   
    	        if(source instanceof JCheckBox)   
    	        {   
    	            ((JCheckBox) source).setEnabled(false);   
    	        }   
    	        if (source instanceof JButton)   
    	        {   
    	            System.out.println("the button");   
    	        } 
     
    	    }    
    }

    I want the computer to pick 1,2, or 3 boxes and so on until all boxes are selected. the player to select the last box wins.

    Please advise.

    It depends if you want the computer to be dumb or smart.

    Dumb: randomly pick 1,2 or 3 boxes.

    Smart: very deep recursion to determine all possible outcomes and choose the optimal one.

    1. You haven't shown the code where your computer is selecting checkboxes.
    2. You can use random values to select checkboxes and each time, a random number is selected, mark that valued checkbox. (This case is not that efficient but a starting way to do, you can make it more efficient by coding it more intelligent.)
