Answer 1

这不是mouseMove的问题，数组下标越界为-1了，是不是下标没控制好啊

Answer 2

Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: -1
同意楼上的说法~lz你再看看你的代码~
at ImageProcessingDemo$MouseMotionObject.mouseMoved(ImageProcessingDemo.java:632) 
找找看有什么错~

Answer 3

ArrayIndexOutOfBoundsException,可事实上我没有用到过数组。

Answer 4

代码非常长，我就问下
Graphics  的 drawString方法是不是要用到数组。
