Sir why we r using this island of isolation ...... simply we can declare t1=null ;t2=null;t3=null directly........ Why we r making this

Hello Prachi.
Plz contact our online team [e-mail] or call us on this number [phone], 7207212427/28

[@tanduyashaswini2581]

This is to prove the scenario where there will be reference to a object but still those are eligible for garbage collector. In your example it is straight forward scenario where if there are no reference exists for an object those would be eligible for garbage collection . but in case of island of objects observe carefully that objects do have reference but those are internal references not external references.

The Example shown in video gives me error.
Code:
package com.any.test;
public class Test {
Test i;
public static void main(String[] args) {
// TODO Auto-generated method stub
Test t1 = new Test();
Test t2 = new Test();
Test t3 = new Test();
System.out.println("Obj t1 = " + t1.i);
System.out.println("Obj t2 = " + t2.i);
System.out.println("Obj t3 = " + t3.i);
t2 = t1.i;
t3 = t2.i; ==> Line 14
t1 = t3.i;
Console(On execution):
Obj t1 = null
Obj t2 = null
Obj t3 = null
Exception in thread "main" java.lang.NullPointerException
at com.any.test.Test.main(Test.java:14)
Can someone explain?
