ArrayList Error in java (Unable to equate two numbers) [duplicate]

This question already has an answer here:

• How to properly compare two Integers in Java? 6 answers

Here is some code

package deleteit;
import java.lang.*;
import java.io.*;
import java.util.*;

public class Deleteit {

public static void main(String[] args) throws IOException {

    BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
    ArrayList<Integer> arr1=new ArrayList<Integer>();
    arr1.add(100000);
    arr1.add(1);
    arr1.add(100000);
    arr1.remove(1);
    if(arr1.get(0)==arr1.get(1))
    {
        System.out.println("GUd");
    }
    else
       System.out.println("damnit");

}

}

Now Gud should be printed as 100000 is equal to 100000 as 1 gets removed from the ArrayList so it is left with 100000 and 100000 . So why does damnit gets printed ?

Is that a BUG?
