How to execute Python script from Java?

Question

I can execute Linux commands like ls or pwd from Java without problems but couldn\'t get a Python script executed.

This is my code:

Answer 1

First, open terminal and type "which python3". You will get the complete path of python3. For example "/usr/local/bin/python3"

String[] cmd = {"/usr/local/bin/python3", "arg1", "arg2"};
Process p = Runtime.getRuntime().exec(cmd);
p.waitFor();

String line = "", output = "";
StringBuilder sb = new StringBuilder();

BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));
while ((line = br.readLine())!= null) {sb = sb.append(line).append("\n"); }

output = sb.toString();
System.out.println(output);
