java - Java 单选按钮提交

Question

您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它们都是独立的（不在 a 中b2），我需要当用户点击提交时，我可以将二进制值（如果按下则为 true，如果未按下则为 false）保存到变量中b3ButtonGroup

//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

如果您在谈论 a JRadioButton，您可以使用该isSelected()方法来了解用户是否检查过它。

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();
