Parameters

obj Specify the object to compare with.

Return Value

Example:

In the example below, 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 = 5;
    Integer val2 = 5;
    Integer val3 = -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
