题目:java拼图游戏姓名学号指导教师（签名）二○一一年七月十四日java拼图游戏[摘要]• 进一步加深对Java语言的理解和掌握：将所学的JAVA知识运用于实践中。
• 课程设计将理论与实践相结合，提供了一个既动手又动脑，独立实践的机会，锻炼我们的分析解决实际问题的能力，提高学生适应实际，实践编程的能力;• 熟练掌握JAVA语言中图形用户界面程序的编写;大体了解怎样用JAVA来编写小游戏的，增强我们实践能力和创新精神的综合培养。
前言编程思路：本练习因为要制作拼图游戏，所以首先要实现图片的导入。
这是通过getImage()函数来实现的，该函数有两个参数，第一个参数指明图片的路径，第二个参数指明图片的名称。
然后，因为要实现图片摆放的随意性，所以要通过initgame()函数来实现。
Initgame()函数是自写函数，在函数体内，通过调用Math.random()函数产生随机数，用来达到图片位置摆放的随意性和随机性。
最后，因为要实现人机交互.，所以首先要通过一系列函数来实现对鼠标事件的监听和响应，这是通过函数addMouseListener(this)和addMouseMotionListener(this)来完成的。
这样程序会区分用户对鼠标不同的操作，正确执行相应的功能。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
