不知道啊换了win7就这样了
你重新下个jdk，重新设置你的系统环境变量path和classpath，然后运行ms-dos，输入javac，如果还是不行，那么可能是jdk不支持win7的操作系统（很有可能），运行后出现乱码，建议你去sun公司官网去找支持win7的jdk下载，如果暂时没有，你只能装双系统了，或者编程时候用Eclipse等ide了
别吓我，win7不兼容java！太可怕了
没用过win7,不过我估计是编码选择问题
你查看下命令行的属性,里面有说当前代码页的编码(XP下如此)
XP之前命令行编码是GBK,vista之后是UTF8好像...
而目前jdk多语言版本的本地编码依然是ANSI
我猜测应该是这个问题
你就先用英文版jdk好了,或者看能不能设置命令行编码,或者使用支持ANSI编码输出的IDE

我试着更换了下自己的cmd编码,将gbk改为了utf8
确实如此
你在命令行下输入
CHCP 936
后,再输入javac
11L的兄弟，太复杂了，搞不懂啊
还有进行输入
CHCP 936
后,再输入javac
结果还是不行
那么你在命令行中直接输入 CHCP
返回结果是什么?
CHCP的返回结果是Active code page: 437
