的错误，我无法弄清楚

Question

确定这样的IM不知道为什么这个程序不能正常工作，我在做这个项目在学校和其未完成的，但现在每当我试图运行它，我得到错误信息

Exception in thread "main" java.lang.Error: Unresolved compilation problem: at Means34.main(Means34.java:96)

即使我删除代码行，所以没有行96我仍然得到这个消息。任何人都可以给我任何想法，为什么发生这种情况？

} 

Answer 1

它编译和我运行良好，但我不得不行

frm.setVisible (True); 

改变

frm.setVisible (true);
