Thread join() method

[Shiva Mohan]

    
class Java_threads extends Thread {
  private int i;
  public void run() {i = 1;}
  public static void main(String[] args) throws InterruptedException {
    Java_threads a = new Java_threads();
    
    a.start();
    System.out.println(Thread.currentThread().getName());
    a.join();
    System.out.print(a.i);
}}

join() is called on Thread-1(that means, reference a) and called by mainthread.That means mainthread will wait until the thread-1(a) will die.
So thread-1 is completed first holding 1 value.then that(1) value is printed for a.i.

I wanted to make sure that I got the join() method correctly.Am i correct...

Yes you are correct.

Here, a.join() means main thread will wait for a to complete. By this way, a will successfully assign 1 to i before main thread prints it.
