Process Class exitValue() method

  • exitValue() method is available in java.lang package.
  • exitValue() method is used to return the exit value of processes and inner processes or sub-processes.
  • exitValue() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
  • exitValue() method may throw an exception at the time of exiting processes or subprocesses.
    IllegalThreadStateException: This exception may throw when the child process denoted by this process has not still terminated.


    public abstract int exitValue();


  • It does not accept any parameter.

Return value:

The return type of this method is int, it returns value 0 then it reflects normal termination of processes.


// Java program to demonstrate the example 
// of int exitValue() method of Process 

import java.util.*;

public class ExitValue {
    public static void main(String[] args) throws Exception {
        // Instantiating Process object
        System.out.println("Process Instantiated");
        Process pr = Runtime.getRuntime().exec("C:\\Program Files (x86)\\TextPad 6\\TextPad.exe");

        // Destroy a process

        System.out.println("Process Destroyed");

        // Destroyed Process with exit value
        System.out.println("Exit value =" + pr.exitValue());


Process Instantiated
Process Destroyed
Exit value =1
