堆内存溢出了 原因是创建对象过多，堆内存满了 简单点 内存中对象太多或者太大装不下了 调试下代码试试

[qq_35539294]

那我该怎办 然后

[abcdefghiijklmnopqrs]

jp1 = new JPanel(); jp2 = new JPanel(); jp3 = new JPanel();加一句这个就行了,运行可以通过

[Jeson_y]

尽量不要用中文命名

[萧乡月夜]

StackOverflowError是栈溢出

[小七和十一的爸爸]

java.lang.StackOverflowError内存溢出

[JPF1024]

内存溢出，避免创建很多对象，不要用中文命名，一开始可以用拼音，

[qq_35539294]

找到错误了 应该是和 本包中的其他类中的对象 一个名了
