java基础-点击按钮更换按钮颜色，并设置默认被选中按钮

用按钮而不是复选框，实现封装一个组件。自动生成一排按钮

public class BaseButtnGroup {

private LovoLabel brandLab;
private List<LovoButton> list = new ArrayList<LovoButton>();
public BaseButtnGroup(String groupName,String[] btnName,Container con,
int x,int y){

brandLab = new LovoLabel(" - - " + groupName + " - - ", x, y, con);
for(int i = 0 ; i < btnName.length ; i++){
x += 100;
LovoButton baseBtn = new LovoButton(btnName[i], x, y, con);

baseBtn.setBackground(Color.CYAN);
if(baseBtn.getText().equals("不限")){
baseBtn.setBackground(Color.green);
}
list.add(baseBtn);
baseBtn.addActionListener(new ActionListener() {

@Override
public void actionPerformed(ActionEvent e) {
changeColor(baseBtn);
JButton bBtn =(JButton)e.getSource();
service(bBtn.getText());
}
});
}

}
public void changeColor(LovoButton baseBtn){
for(LovoButton temp : list){
if(temp == baseBtn){
temp.setBackground(Color.green);
}else{
temp.setBackground(Color.CYAN);
}

}
}
public void service(String info){

}

}
