Scanner library issue in java

Question

Why if condition become false value even if the ans is hell. Is there something wrong with the program or what. I am using blueJ for java.

import java.util.Scanner;
public class QuizContest
{
Scanner value = new Scanner(System.in);
public void Contest()
{
    System.out.println("Please type- hell");
    String ans=value.next();       
    if(ans=="hell")
    {
        System.out.println("Congratulation. You are right");
    }
    else
    {
        System.out.println("You are wrong");
    }
}
}

Comaparing string in java should be done with equals(), not == change:

if(ans=="hell")

to:

if(ans.equals("hell"))

When you are comparing with ==, you expect both arguments to be the exact same instance in memory. this works well with primitives, but not with objects like String
