running java main class using subprocess.Popen in python -

i want execute java main class main.java python using subprocess.popen(). main.java takes 3 args.

i wonder how it? example have helloworld.java class:

public class helloworld {     public static void main(string[] args) {         system.out.println("hello world!" + args[0]);     } } 

i tried call in python using command:

print (subprocess.popen('java c:/users/testing/hello.main sayhello', shell=true, stdout=subprocess.pipe).stdout.read())

where 'sayhello' string args want pass in. said

error: not find or load main class c:.users.testing.hello.main

thanks

you may run java file extension .class following way:

java your.path.main arg1 arg2 

where,

• java - command, runs java interpreter
• your.path.main - full name of class (without .class)
• arg1 arg2 - arguments (written spaces or between ")

further, when formatted line, transmits in subprocess.popen() argument.

subprocess.popen('java your.path.main arg1 arg2') 

i'm not python programmer, because advice read documentation method.
