对复选框进行分组并获取java中复选框的选定值

Question

如何在下面的代码中对复选框进行分组？如何在java中获取它的复选框的选定值？

// CHECKBOXES
JCheckBox cb_CCP = new JCheckBox("Chinese Cultural Places");
JCheckBox cb_HandCP = new JCheckBox("Heritage & Culture Places");
JCheckBox cb_HCentres = new JCheckBox("Heritage Centres");
JCheckBox cb_HMuseums = new JCheckBox("Heritage Museums");
JCheckBox cb_ICP = new JCheckBox("Indian Cultural Places");
JCheckBox cb_MCP = new JCheckBox("Malay Cultural Places\r\n");
JCheckBox cb_HTrails = new JCheckBox("Heritage Trails");
JCheckBox cb_PCP = new JCheckBox("Peranakan Cultural Places");

Answer 1

要进行分组，您需要ButtonGroup

ButtonGroup bg = new ButtonGroup();
bg.add(cb_CCP);
bg.add(cb_HandCP);
.. and so on

添加要分组的复选框。通过分组，您可以选择只有一个。

要检查选择了哪一个，这应该在你的听众中

if (cb_CCP.isSelected()){
    String s = cb_CCP.getText();
    // do something
} else if (cb_HandCP.isSelected()){
    // do something
} else if (.....){
    ...
}
