[java] How to Compare a long value is equal to Long value

long a = 1111;
Long b = 1113;

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

the above code prints a "equals" in console, which is wrong answer. my qestions is how to compare a long variable value is equals to Long variable value. please replay me as soon as possible.

Thankh you

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("Equals");
        } else {
            System.out.println("not equals");
        }
    }

prints

not equals for me

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

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.

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));

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

    public static void main(String[] args) {
        long a = 1111;
        Long b = 1113L;
        if(a == b.longValue())
    {
        System.out.println("Equals");
    }else{
        System.out.println("not equals");
    }
  }

or:

    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");
    }
  }

long a = 1111;
Long b = new Long(1113);

System.out.println(b.equals(a) ? "equal" : "different");
System.out.println((long) b == a ? "equal" : "different");
