I will share that How do I do it since Java 7 -

Long first = 12345L, second = 123L;
System.out.println(first.equals(second));

output returned : false

and second example of match is -

Long first = 12345L, second = 12345L;
System.out.println(first.equals(second));

output returned : true

So, I believe in equals method for comparing Object's value, Hope it helps you, thanks.

It works as expected  Try checking IdeOneDemo  public static void main String   args            long a   1111          Long b   1113l           if  a    b                System out println  quot Equals quot              else               System out println  quot not equals quot                     prints not equals for me Use compareTo   to compare Long     wil not work in all case as far as the value is cached

On the one hand Long is an object  while on the other hand long is a primitive type  In order to compare them you could get the primitive type out of the Long type   public static void main String   args        long a   1111      Long b   1113       if   b  null  amp  amp           a    b longValue                    System out println  Equals               else                System out println  not equals

long a   1111  Long b   new Long 1113    System out println b equals a     equal     different    System out println  long  b    a    equal     different

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

Since Java 7 you can use java util Objects equals Object a  Object b       These utilities include null-safe or null-tolerant methods   Long id1   null  Long id2   0l  Objects equals id1  id2
