Run a Java program

Simon Thies

I wan´t to run an program with Notepad ++. But it keeps saying this:
; about to start a child process: “java Test”
CreateProcess() failed with error code 2:
The System can´t find the file.

What can I do to fix that?

On the rare occasions I run Java from Notepad++ (I think it’s been a couple years since I tried playing with Java), I use the NppExec plugin to run the script

NPP_SAVE
cd "$(CURRENT_DIRECTORY)"
"C:\Program Files (x86)\Java\jdk1.8.0_51\bin\javac" $(FILE_NAME)
"C:\Program Files (x86)\Java\jdk1.8.0_51\bin\java" -classpath "$(CURRENT_DIRECTORY)" $(NAME_PART)

I realized I didn’t really complete my thought.

You can define that script in the Plugins > NppExec > Execute dialog, and Save… it with a meaningful name (I use Java-CompileAndRun) , then use that plugin’s Advanced Options interface to add the script to the Macro menu (may require reloading Notepad++ after that). After it’s in that menu, you can use Shortcut Mapper to assign it a keyboard shortcut.

From then on, if you have a java source code in the active editor tab, running that script through the Macro menu or through the keyboard shortcut will compile and execute the active java program.
