Java - Integer equals() Method

The java.lang.Integer.equals() method is used to compare this object to the specified object. The result is true if and only if the argument is not null and is an Integer object that contains the same int value as this object.

Syntax

Example:

In the below example, the java.lang.Integer.equals() method is used to compare given Integer objects for equality.

import java.lang.*;

public class MyClass {
  public static void main(String[] args) {
    
    //creating Integer objects
    Integer val1 = new Integer("5");
    Integer val2 = new Integer("5");
    Integer val3 = new Integer("-5");

    //checking Integer objects for equality
    System.out.println("Is val1 == val2?: " + val1.equals(val2)); 
    System.out.println("Is val1 == val3?: " + val1.equals(val3));    
  }
}

The output of the above code will be:

Is val1 == val2?: true
Is val1 == val3?: false
