多个单选按钮被选中

Question

我有两个用 java 制作的单选按钮。问题是它们没有链接在一起，即它们都可以同时被选中。我如何实现它们之间的链接？

Answer 1

设置相同的name属性 Radio example

<input id="hello" type="radio" name="greet">
<label for="hello">hello</label>
<input id="hi" type="radio" name="greet">
<label for="hi">hi</label>
<hr />
<input id="all" type="radio" name="who">
<label for="all">world!</label>
<input id="one" type="radio" name="who">
<label for="one">you</label>

Answer 2

我认为你需要这个；

        //Create three radio buttons   
        JRadioButton aButton = new JRadioButton("A",true);
        JRadioButton bButton = new JRadioButton("B");
        JRadioButton cButton = new JRadioButton("C");

        //Create a ButtonGroup object, add buttons to the group
        ButtonGroup myButtonGroup = new ButtonGroup();
        myButtonGroup.add(aButton);
        myButtonGroup.add(bButton);
        myButtonGroup.add(cButton);

        //Display radio buttons
        getContentPane().setLayout(new FlowLayout());
        getContentPane().add(aButton);
        getContentPane().add(bButton);
        getContentPane().add(cButton);
        setSize(250,100);
        setTitle("Swing Radio Buttons");
        setVisible(true);

如果有帮助，请告诉我。
