Q1: 用JAVA写出源代码。运行结果如下？

您好：

  代码及运行结果如下，供参考：

代码示意图

运行结果示意图

  因输出的内容中包含特殊字符，所以在输出的时候，需要做转义，以上代码供参考。

Q2: 求一个java图片浏览器的源代码，拜托大家了！！！

给你代码，看一下注释，为是防止左右移动时鼠标是水平的移动，所以加了一个范轩，

在二十个象素内，认为是水平的。

你看一下吧

还好你这个是鼠标按住移动，如果只是鼠移动就麻烦了

Q5: 求java绘图程序源代码（加注释），在如下图的基础上，在图案种类上添加圆角矩形，求代码

直线 是 Line2D

矩形是 Rectangle2D

弧 Arc2D

椭圆 Ellipse2D

圆角矩形是 RoundRectangle2D

上面的都在 java.awt.geom包里
