猜数字小游戏

一个猜数字小游戏，大二实训自做

前言

刚做出来,没什么好说的，本来也就不是啥大项目
初代版本，没改字体颜色大小啥的，可以自己改
不过自己能做出来，很高兴
废话不多说，直接放源码

源码

一个GuessNumFrame类
同时还用了一个封装好的本地工具类：LocationUtil
注意代码中图片地址非确定，改为自己的

GuessNumFrame类:

import javax.swing.JLabel;

LocationUtil 类:

package top.handsomelv.study.util;

import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.awt.event.MouseMotionAdapter;

import javax.swing.JFrame;

/*
	 * 封装一个工具类
	 * 设计模式的一种：高内聚，低耦合
	 * 1）点击窗口的时候，输出点击的位置x,y
	 * 2）鼠标操作，窗体跟随鼠标移动
	 * 
	 */
public class LocationUtil {
	
	JFrame fram;
	private boolean isDraging = false;
	private int xx,yy;
	//重写构造器，添加形参
	public LocationUtil(JFrame frame) {
		this.fram =frame;
		//监听事件
		fram.addMouseListener(new MouseAdapter() {
			@Override
			public void mousePressed(MouseEvent e) {
				super.mousePressed(e);
				isDraging = true;
				xx = e.getX();
				yy = e.getY();
				System.out.println("=="+xx+":"+yy);
			}
			
			@Override
			public void mouseReleased(MouseEvent e) {
				
				super.mouseReleased(e);
				isDraging = false;
				
				
			}
		});
		
		fram.addMouseMotionListener(new MouseMotionAdapter() {
			@Override
			public void mouseDragged(MouseEvent e) {
				
				super.mouseDragged(e);
				if (isDraging) {
					int left = fram.getLocation().x;
					int top = fram.getLocation().y;
					fram.setLocation(left+e.getX(),top+e.getY());
				}
			}
		});
	}
