我学习Java时做的实验题目的一些答案，可供正在学习Java的莘莘学子们参考一下，应该有你想要的实验的答 案。部分题目如下，可看一下和你们老师布置的实验题目是否一样：编写一个程序输出如下图案。编制applet 程序，绘制一个长120、宽80的红色矩形，并在矩形内部绘制一个兰色内切椭圆。设有一批英文单词存放在一个 数组中，编制一个图形界面程序浏览单词。在界面中安排一个标签显示单词，另有“上一个”、“下一个”两 个按钮实现单词的前后翻动。编写一个鼠标位置跟踪程序，在鼠标所在位置为中心绘制一个红色十字架。编制 一个声音播放控制程序，在Applet面板上安排“播放”和“停止”两个按钮，点击“播放”将播放声音，点击 “停止”可停止播放。另外，Applet启动和离开时将自动播放和停止播放，要播放的声音文件名由Applet参数 提供。有一个南北向的桥，只能容纳一个人，现桥的两边分别有10人和12人，编制一个多线程序让这些人到达 对岸，每个人用一个线程表示，桥为共享资源。在过桥的过程中显示谁在过桥及其走向。编写一个可变颜色的 标签，用一个按钮控制颜色的改变与停止。点击按钮颜色停止变化，再点击该按钮颜色又变化。颜色的变化可 用随机数确定。编写一个图片播放程序，图片的文件名为 file01.jpg，file02.jpg，…filen.jpg, 其中n由命 令行输入，要求用多线程自动播放。1）设有一个由10个英文单词构成的字符串数组，要求： （1）统计以字母w开头的单词数； （2）统计单词中含“or”字符串的单词数； （3）统计长度为3的单词数。 创建一个程序，输出今天的年、月、日。 提示：创建一个java.util.Date类的对象代表当前的系统日期，使用对象的getYear()方法、getMonth()方法、 getDay()方法可获得对应的年月日。编写一个三角形类，能根据3个实数构造三角形对象，如果三个实数不满足 三角形的条件，则自动构造以最小值为边的等边三角形。输入任意三个数，求构造的三角形面积。1) 利用随机 函数定义10对(x,y)值，由此创建的Point类实例存入一个数组中，按与原点（0，0）的距离由小到大的顺序输 出所有的点及到原点的距离。 编写一个人与计算机对拿火柴的游戏程序。利用随机函数Math.random()产生火 柴数量（20～50)， 每次最多拿3根，拿到最后一根为胜者。 要求：游戏过程要显示火柴总数，选择谁先拿；每步要显示剩余火柴数量，以及计算机拿的数量，并提示用户 输入拿多少；结束时显示谁是胜者。 【解题算法提示】 (1) 产生火柴总数（amount）； (2) 决定随先拿（whoplay：1--人， 2--计算机）； (3) 定义一个变量保存剩余火柴数量（remain)=amount ； (4) 当remain>0 循环 4.1 根据whoplay的值决定是计算机拿x根还是提示人拿x根；计算机拿时最好带有智能，人拿时要限制输 入数量。 4.2 修改 whoplay的值； 4.3 修改remain的值； (5) 根据whoplay的值决定胜者
