Java 使用单选按钮更改GUI的颜色

我写了一个程序，它有两个数组的图形显示。一个是充满随机数，另一个是通过气泡排序排列的数字。然后，程序获取这两个数组，并根据数组第i个位置的数字值，通过对正方形进行着色来显示它们。然后，我尝试修改代码，加入一些单选按钮，以更改显示屏的主题颜色，红色、绿色或蓝色。当选择一个按钮时，显示良好，但当按下另一个按钮时，颜色变为所选按钮的组合（例如，红色和绿色为黄色，所有三个按钮均为白色），并且您也不能取消选择颜色

我的问题是：如何修改代码，使GUI上的单选按钮可以在三种颜色之间反复切换，而不是它们的任何组合

对于（int i=0；i对于
JRadioButton
侦听器中的（inti=0；i），您还需要清除其他颜色。否则，您将混合使用它们

例如：

B.addActionListener(new ActionListener(){
    public void actionPerformed(ActionEvent e){
        if(B.isSelected()){
            bubPan.setR(0);  //added this
            bubPan.setG(0);  //added this
            bubPan.setB(1);         
        }else if(!B.isSelected()){
            bubPan.setB(0);
        }
        repaint();
    }
});

并对其他按钮执行相同操作。
您正在设置R、G和B值，但未设置其他2个。请将不同口味的操作替换为以下内容
