调用JRadioButton的isSelected方法判断
给你贴一个很简单的实例import javax.swing.*;
import java.awt.*;
import java.awt.event.*;public class JRadioButtonDemo1 extends JFrame{
private ButtonGroup genderGroup=null;
private JRadioButton boyBtn=null;
private JRadioButton girlBtn=null;

public JRadioButtonDemo1(){}

public JRadioButtonDemo1(String title){
super(title);
boyBtn=new JRadioButton("boy");
girlBtn=new JRadioButton("girl");
genderGroup=new ButtonGroup();
genderGroup.add(boyBtn);
genderGroup.add(girlBtn);

this.getContentPane().setLayout(new FlowLayout());
this.getContentPane().add(boyBtn);
this.getContentPane().add(girlBtn);

girlBtn.addActionListener(new ActionListener(){ @Override
public void actionPerformed(ActionEvent arg0) {
// TODO Auto-generated method stub
System.out.println(girlBtn.getText());
System.out.println("girlBtn is selected is "+girlBtn.isSelected());

}

});

boyBtn.addActionListener(new ActionListener(){ @Override
public void actionPerformed(ActionEvent arg0) {
// TODO Auto-generated method stub
System.out.println(boyBtn.getText());
System.out.println("boyBtn is selected is "+boyBtn.isSelected());

}

});


this.pack();
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setLocationRelativeTo(null);
this.setVisible(true);
}

public static void main(String[] args){
new JRadioButtonDemo1("Demo");
}}
