Java单选按钮提交

Question

如何查看是否选择了按钮并将其用作二进制值

我有3个单选按钮b1，b2，b3，它们都是独立的（不在ButtonGroup中），我需要在用户点击提交时可以保存二进制值（如果按下则为true，如果未按下则为false）保存到变量

//Gets details when submit is pressed
submit.addActionListener(new ActionListener()
{
    public void actionPerformed(ActionEvent e)
    {
        String name = t.getText();
        String surname = t1.getText();
        String studentID = t2.getText();
        //Code to place binary values into variables depending on the radio buttons selected
    }
});

Answer 1

如果您正在谈论JRadioButton，则可以使用isSelected()方法来了解用户是否进行了检查。

String name = t.getText();
String surname = t1.getText();
String studentID = t2.getText();
boolean checked = myRadioButton.isSelected();
//...

Answer 2

boolean button1 = b1.isSelected();
boolean button2 = b2.isSelected();
boolean button3 = b3.isSelected();
