"Javac" doesn't work correctly on Windows 10
提问by Sad?k
the problem is that I upgraded to Windows 10 and now I'm installing my tools to programming and now that I installed the JDK 7 of Java, when I try to use in the cmd the command: - "javac"
问题是我升级到了 Windows 10，现在我正在安装我的编程工具，现在我安装了 Java 的 JDK 7，当我尝试在 cmd 中使用命令时：-“javac”
The result of this is: "javac" is not recognized as an internal or external command...
这样做的结果是：“javac”未被识别为内部或外部命令...
But I was edited the PATH with the correct link of jdk, because when I use "java", it is ok.
但是我用jdk的正确链接编辑了PATH，因为当我使用“java”时，它是可以的。
Now, I tryed in the console with this command: PATH=%PATH%;"C:\Program Files\Java\jdk1.7.0_79\bin"
现在，我在控制台中尝试使用以下命令： PATH=%PATH%;"C:\Program Files\Java\jdk1.7.0_79\bin"
And when I ejecute this command, when I use "javac" it works, but now, when I open other console, it doesn′t work, or when I restart the console, this command is not recognized.
当我弹出这个命令时，当我使用“javac”时它可以工作，但是现在，当我打开其他控制台时，它不起作用，或者当我重新启动控制台时，无法识别此命令。
What could be the problem?
可能是什么问题呢？

just add C:\Program Files\Java\jdk1.7.0_80\bin as the path in environmental variables. no need to add java.exe and javac.exe to that path. IT WORKS
只需添加 C:\Program Files\Java\jdk1.7.0_80\bin 作为环境变量中的路径。无需将 java.exe 和 javac.exe 添加到该路径。有用

For some reason it worked for me to add quotation marks to the path folder on windows 10. not C:\Program Files\Java\jdk 1.8.0_111\bin, but "C:\Program Files\Java\jdk 1.8.0_111\bin".
出于某种原因，我在 Windows 10 上的路径文件夹中添加引号对我有用。不是 C:\Program Files\Java\jdk 1.8.0_111\bin，而是“C:\Program Files\Java\jdk 1.8.0_111\斌”。

After adding C:\Program Files\Java\jdk1.8.0_73\bin to the system variables I turned off my command prompt and opened another one. Then it worked.
将 C:\Program Files\Java\jdk1.8.0_73\bin 添加到系统变量后，我关闭了命令提示符并打开了另一个。然后它起作用了。
