Threads implement their own stack - demonstration using program and diagram in java






Yes, Threads have their own stack. This is very interesting question, where interviewer tends to check your basic knowledge about how threads internally maintains their own stacks. I’ll be explaining you the concept by diagram.




Program used for demonstrating how threads implements their own stack >
class MyThread extends Thread{
   public void run(){
          System.out.println("in run() method");
   }
}

/** Copyright (c), AnkitMittal JavaMadeSoEasy.com */
public class MyClass {
   public static void main(String...args){
          System.out.println("In main() method");
          method1();
   }
  
   static void method1(){
          MyThread obj=new MyThread();  
          obj.start();
   }
}
/*OUTPUT
currentThreadName= main
in run() method
currentThreadName= Thread-1
*/
