我的单选按钮出现问题.我可以同时点击这三个.它应该是当你点击一个时另一个关闭？
我正在使用网格布局.所以当我尝试group.add它不起作用.
例:
我有这样的按钮
JRadioButton seven = new JRadioButton("7 years at 5.35%", false);
JRadioButton fifteen = new JRadioButton("15 years at 5.5%", false);
JRadioButton thirty = new JRadioButton("30 years at 5.75%", false);
ButtonGroup group = new ButtonGroup();
grid.add(seven);
grid.add(fifteen);
grid.add(thirty);
这是我的代码:
/*Change Request #6

the term …我是学生这是家庭作业......桌子在那里,但没有插入数据.
谢谢你的建议
