How to execute a Python program and gather return output in Java
Hi, I have python code that accepts a command line argument and uses NLTK to determine the classification of that argument and the accuracy of fitting that classification. It prints the results to the console for now. I would like to call this python code in java and supply the command line arg and then gather the return output.
I know I can use the following code to execute the python program
However, I'm not sure how to get the printed results from the console into my java program. Can anyone help me out?

String[] command = {"/bin/bash", "-c", "python3 " + scriptLocation + " < " + scriptArgs.getAbsolutePath()};
log().info(command[0] + " " + command[1] + " " + command[2]);
ProcessBuilder builder = new ProcessBuilder(command);
builder.redirectErrorStream();
Process process = builder.start();
process.waitFor();
However, I'm not sure how to get the printed results from the console into my java program. Can anyone help me out?
