Syntax:

public static int compare(double d1, double d2)

Parameters:

This accept work with two parameters;

• d1: The first Double value that needs to compare.
• d2: The second Double value that needs to compare. ##Return Value: This function will return the following values.

0: if both the numbers are equal.
Negative value: if the value of d1 is less than d2.
Positive value: if the value of d1 is larger than d2.

Example Code:

import java.lang.Double;

public class GFG {

               public static void main(String[] args)

               {
                     // Get the two double values

                               // to be compared

                               Double d1 = 10d;

                               Double d2 = 1023d;



                               // function call to compare two double values

                               // if d1 and d2 are same                             

                           if (Double.compare(d1, d2) == 0) {

                                               System.out.println("d1=d2");

                               }

//id d1 is less than d2

                               else if (Double.compare(d1, d2) < 0) {

                                               System.out.println("d1<d2");

                               }

//if d1 is greater than d2

                               else {

                                               System.out.println("d1>d2");

                               }

               }

} 

Output:

The output of the above program will be d1.
