使用Path解决方案后，我无法获得命令提示符以读取Javac命令。 （Windows 8.1 64位）

Question

I keep getting the reading:

'javac' is not recognized as an internal or external command, operable program or batch file

Here is my current Path with java included:

C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;
C:\ProgramData\Oracle\Java\javapath;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;
C:\Program Files (x86)\Windows Live\Shared;
C:\Program Files (x86)\GtkSharp\2.12\bin;
C:\Program Files (x86)\Java\jre1.8.0_91\bin

Not sure what I am missing. I have restarted my computer as well. Any suggestions? To be clear I am a first semester CS Student with 0 experience, so I might not understand certain terminology.

Answer 1

You have included JRE :

C:\Program Files (x86)\Java\jre1.8.0_91\bin

You must include JDK like:

C:\Java\jdk1.8.0_181\bin

Answer 2

Your path includes C:\\Program Files (x86)\\Java\\jre1.8.0_91\\bin - it's JRE (runtime). javac is a program from JDK (development kit). JRE is a part of of JDK, not vice versa.

Download and install JDK (or check does it exists something like C:\\Program Files (x86)\\Java\\jdk1.8.0_91\\bin )
