ProcessBuilder won't run with arguments [duplicate]

Question

I am trying to run "java -version" using ProcessBuilder:

processBuilder = new ProcessBuilder("java -version");
process = processBuilder.start();

However I get an error:

java.io.IOException: Cannot run program "java -version": CreateProcess error=2, The system cannot find the file specified

When I remove the "-version" and do:

processBuilder = new ProcessBuilder("java");
process = processBuilder.start();

it runs fine and I get the normal help guide output.

How can I get it to run the argument too?

Answer 1

The complete argument is being interpreted as the executable. Use

ProcessBuilder processBuilder = new ProcessBuilder("java", "-version");
