multithreading - Programatically check if two threads belong to the same process in Java -


how check if 2 threads belong same or different processes programatically? piece of code have written:

public class mythread {      public static void main(string[] args) {         testthread1 obj1 = new testthread1();         testthread2 obj2 = new testthread2();         system.out.println("current thread:" + thread.currentthread().getname());         thread t1 = new thread(obj1);         t1.start();         thread t2 = new thread(obj2);         t2.start();       } }  class testthread1 implements runnable {     @override     public void run () {         for(int i=0; i<1000 ;i++) {             try {                 thread.sleep(1000);             } catch (interruptedexception e) {                 e.printstacktrace();  //to change body of catch statement use file | settings | file templates.             }             system.out.println("current thread:" + thread.currentthread().getname());         }     } }  class testthread2 implements runnable {     @override     public void run () {         for(int i=0; i<1000 ;i++) {             try {                 thread.sleep(1000);             } catch (interruptedexception e) {                 e.printstacktrace();  //to change body of catch statement use file | settings | file templates.             }             system.out.println("current thread:" + thread.currentthread().getname());         }     } }

here understand thread t1 being created part of process testthread1 , thread t2 being created part of testthread2 process. how check programatically?

you mixed concept of threads , processes.

thread t1 being created part of process testthread1 , thread t2 being created part of testthread2

your testthread1 , testthread2 runnables, hold information action should done thread. t1 , t2 actual threads, run in same process, because started them in 1 application. threads in application run in same java process, can't have situation have 2 threads referecens , belong different processes.

if start java application, run in different process, won't able compare 2 threads different processes in single context.
