关于《北京浮生记》java编程的思路

import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import javax.swing.JLabel;

public class Test {
	static int status=0;
	JLabel label1;
	JLabel label2;
	public JLabel getLabel1() {
		if(label1==null){
			label1=new JLabel();
			label1.setText("海淀大街");
			label1.addMouseListener(new MouseAdapter(){
				@Override
				public void mouseClicked(MouseEvent e) {
					super.mouseClicked(e);
					changLabelsText();
				}
			
			});
		}
		return label1;
	}
	public void setLabel1(JLabel label1) {
		this.label1 = label1;
	}	
	
	public JLabel getLabel2() {
		if(label2==null){
			label2=new JLabel();
			label2.setText("亚运村");
			label2.addMouseListener(new MouseAdapter(){
				@Override
				public void mouseClicked(MouseEvent e) {
					super.mouseClicked(e);
					changLabelsText();
				}
			
			});
		}
		return label2;
	}
	public void setLabel2(JLabel label2) {
		this.label2 = label2;
	}
	void changLabelsText() {
		status=(status+1)%4;//假设status有四种状态
		if(status==0){
			label1.setText("海淀大街");
			label2.setText("亚运村");
		}else if(status==1){
			label1.setText("海淀黄庄站");
			label2.setText("亚运村站");
		}else if(status==2){
			label1.setText("海淀");
			label2.setText("亚运");
		}else if(status==3){
			label1.setText("黄庄");
			label2.setText("啊");
		}
	}
