How to Compare a long value is equal to Long value

Question

long a = 1111;
Long b = 1113;
    
if (a == b) {
    System.out.println("Equals");
} else {
    System.out.println("not equals");
}

The above code prints "equals", which is wrong.

How do I check whether a long value equals a Long value?

Answer 1

First your code is not compiled. Line Long b = 1113;

is wrong. You have to say

Long b = 1113L;

Second when I fixed this compilation problem the code printed "not equals".

Answer 2

It works as expected:

public static void main(String[] args) {
    long a = 1111;
    Long b = 1113l;

    if (a == b) {
        System.out.println("Equals");
    } else {
        System.out.println("not equals");
    }
}

prints not equals.

Use compareTo() to compare Long, == wil not work in all case as far as the value is cached.
