No, you can not directly call run method to start a thread. You need to call start method to create a new thread. If you call run method directly , it won’t create a new thread and it will be in same stack as main. Lets understand with the help of example: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 package org . arpit . java2blog ; class CustomThread extends Thread { public void run ( ) { for ( int i = 0 ; i < 5 ; i ++ ) { try { Thread . sleep ( 300 ) ; } catch ( InterruptedException e ) { e . printStackTrace ( ) ; } System . out . println ( "Thread is running :" + i ) ; } } } public class StartThreadAgainMain { public static void main ( String [ ] args ) { CustomThread ct1 = new CustomThread ( ) ; CustomThread ct2
