这是我为你做一个例子：

import java.awt.BorderLayout; 
import java.awt.event.ActionEvent; 
import java.awt.event.ActionListener; 
import javax.swing.JButton; 
import javax.swing.JCheckBox; 
import javax.swing.JFrame; 
import javax.swing.JOptionPane; 
import javax.swing.SwingUtilities; 

public class TestJCheckBox { 

    private JFrame frame; 
    private JCheckBox jcb; 
    private JButton button; 

    public TestJCheckBox() { 
     initComponents(); 
    } 

    private void initComponents() { 
     frame = new JFrame("Test"); 
     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
     frame.setResizable(false); 

     jcb = new JCheckBox("JCheckBox1"); 

     button = new JButton("Is JCheckBox selected?"); 
     button.addActionListener(new ActionListener() { 
      @Override 
      public void actionPerformed(ActionEvent ae) { 
       if (jcb.isSelected()) { 
        JOptionPane.showMessageDialog(frame, "JCheckBox is selected"); 
       } else { 
        JOptionPane.showMessageDialog(frame, "JCheckBox is NOT selected"); 

       } 
      } 
     }); 

     frame.add(jcb, BorderLayout.CENTER); 
     frame.add(button, BorderLayout.SOUTH); 

     frame.pack(); 
     frame.setVisible(true); 
    } 

    public static void main(String[] args) { 
     SwingUtilities.invokeLater(new Runnable() { 
      @Override 
      public void run() { 
       new TestJCheckBox(); 
      } 
     }); 
    } 
}
