Cannot run Java from the Windows PowerShell command prompt

Question

I have Java installed on my machine (the JRE is under C:\\Program Files\\Java) but I can\'t run any java command from the Windows PowerShell command prompt.

Answer 1

If it works in the regular shell but not in PowerShell, maybe you had PowerShell open when you installed or set your path and you just need to close PowerShell and reopen a new one to pick up the new path.
