What is the Java equivalent of Python's subprocess.Popen()?

Question

import subprocess
import os

prefix = os.path.expanduser("~/.bin/kb/")
p = subprocess.Popen([(prefix + "koreball"),(prefix + "/data"),'3'])

Answer 1

It's not clear what you're asking, but if you're looking for the Java equivalent of Popen(), you want Runtime.exec().

Answer 2

Your can try with the Runtime.exec method.

Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec("myprocess");

The method returns a Process that can be used to:

• Retrieve the process output, input and error streams
• Retrieve the process output code
• Kill the process
• Wait for the end of the process execution
