I just install jdk and jre version 8 In windows. Environment variable already set. I try run "java -version" in cmd and it shows the version of java installed. But when I try to compile java project with "javac projectName" system says javac is not recognized as internal or external command. So can anyone tell me how to fix it?

这是我的环境变量:

推荐答案

您的变量路径中有一个拼写错误:

There is a typo in your variable path:

C:Program FileJavajdk1.8.0_60in;C:Program FileJavajdk1.8.0_60in;

应该是而且你不需要两次

Should be and you do not need it twice

C:Program FilesJavajdk1.8.0_60in;
