JRadioButton调用选项

Question

代码如下：

  String male = "Male";
  String female = "Female";

 JRadioButton checkGenderMale = new JRadioButton(male);
      checkGenderMale.addActionListener(new genderListener());

JRadioButton checkGenderFemale = new JRadioButton(female);
      checkGenderMale.addActionListener(new genderListener());

class genderListener implements ActionListener{
   public void actionPerformed(ActionEvent event){
       System.out.println( );
   }
}

在System.out.println()行中，我希望打印选项(所选的字符串公或母)。那么括号中可能会有什么内容呢？

Answer 1

你需要写下

AbstractButton aButton = (AbstractButton) actionEvent.getSource();
System.out.println("Selected: " + aButton.getText());

在您的操作执行方法中。
