Why is the following Java codes output 523 instead of 52 imp

Why is the following Java code\'s output [5,2,3] instead of [5,2]?

import java.util.*;
public class Temp {
   public static void main(String[] args){
   List <Integer>list = new ArrayList<Integer>();
       list.add(5);
       list.add(3);
       list.add(1, 2);
       list.add(3);
       list.add(list.size()-1,3);
       int count=0;
       while(count<list.size()){
           if(list.get(count)==3){
               list.remove(count);
           }
           count++;
       }
       System.out.println(list);
      
      
}
}

J Temp java 3 import java.util. public class Temp e public static void main (String args) List

Solution

Lets take it step by step

list.add(5); => list -> |5|

list.add(3); => list -> |5|3|

list.add(1, 2); => add 2 at index 1 (currently 3 is at index 1) => list -> |5|2|3|

list.add(3); => list |5|2|3|3|

list.add(list.size()-1,3); (add 3 at end) => list -> |5|2|3|3|3|

So list is 5->2->3->3->3

Lets walk through while loop

final remaining list [5,2,3].
