Example:

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

import java.lang.*;

public class MyClass {
  public static void main(String[] args) {
    
    //creating Double objects
    Double val1 = 5.2;
    Double val2 = 5.2;
    Double val3 = -5.2;

    //checking Double 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
