java Swing 获取单选按钮的值，复选框的值

我做的简单程序（用jbuilder做的），大家帮我看看怎样才能在我点“提交”按钮时，获得单选按钮的值，和复选框的值 package helloworld;import java.awt.*;import javax.swing.*;import com.borland.jbcl.layout.XYLayout;import com.borland.jbcl.layout.*;import java.awt.event.ActionEvent;import java.awt.event.ActionListener; public class Frame1 extends JFrame { XYLayout xYLayout1 = new XYLayout(); JLabel jLabel1 = new JLabel(); JRadioButton jRadioButton1 = new JRadioButton(); JRadioButton jRadioButton2 = new JRadioButton(); JButton jButton1 = new JButton(); public Frame1() { try { jbInit(); } catch (Exception exception) { exception.printStackTrace(); } } private void jbInit() throws Exception { getContentPane().setLayout(xYLayout1); jLabel1.setText("性 别："); xYLayout1.setWidth(326); xYLayout1.setHeight(214); jButton1.setText("提 交"); jButton1.addActionListener(new Frame1_jButton1_actionAdapter(this)); jRadioButton2.setText("女"); this.getContentPane().add(jButton1, new XYConstraints(124, 135, -1, -1)); this.getContentPane().add(jLabel1, new XYConstraints(49, 60, 46, 21)); this.getContentPane().add(jRadioButton1, new XYConstraints(127, 60, -1, -1)); this.getContentPane().add(jRadioButton2, new XYConstraints(216, 60, -1, -1)); jRadioButton1.setText("男"); } public void jButton1_actionPerformed(ActionEvent e) { }}class Frame1_jButton1_actionAdapter implements ActionListener { private Frame1 adaptee; Frame1_jButton1_actionAdapter(Frame1 adaptee) { this.adaptee = adaptee; } public void actionPerformed(ActionEvent e) { adaptee.jButton1_actionPerformed(e); }}以下是视图：

Answer 1

每个按钮都有一个boolean值表示是否被选中（用isSelected方法获取），根据这个来判断就行了

Answer 2

首先你应该在你所点击的那个按钮建立按钮监听程序，这是首要的。要获得按钮值和复选框的内容可以这样写在testfeild里面：jtextfeild1.setText(jButton1.g etaction commond )
