JFrame 去掉  c.add()行 c. 去掉 ok

不行，还是不行

图片位置是src下建的img包 可以运行 你对照看下吧

我在eclipse上面运行就是不显示图片，按钮也不显示，就是一个空空的JFrame框

经常都有朋友问如何学好JAVA，网上已经说了很多，我也写了很多关于这方面的文章，但还是有很多朋友

不停在问，这到底是什么原因讷，其实问这个问题的朋友只是不知道大家谁说的是真话，也不知道以前说

的现在还实用不，这里，我再与大家简单的分享一下，如何学好JAVA：多看，多炼，多思考，多重复前三

多，来源java. java学习服务舟，欢迎与java船长做朋友

图片在按钮上面好吧 你要确定你img包下面有图片 没有图片就会报错  有图片 还不报错又不显示 那你再把代码贴出来我看看 或者密我 qq530928601 注明bccn
