Java Double.compareTo() Method

The compareTo() method of Double class compares two double values numerically.

Syntax

Parameters

anotherDouble - the Double value to be compared

Return value

This method returns the value-

Zero, if anotherDouble has same value as this Double.
Positive value, if anotherDouble has a greater value than that of this Double.
Negative value, if anotherDouble has less value than that of this Double.

Example 1

public class  DoubleCompareToMethodExample1 {
    public static void main(String[] args) {

        Double doubleValue1 = new Double("10");

        Double doubleValue2 = new Double("10.44");

        //compares two Double objects numerically

        int compare=doubleValue1.compareTo(doubleValue2);

        if(compare > 0){

            double sub = (doubleValue1 -  doubleValue2);

            System.out.println(doubleValue1+" is greater. \nAnswer after subtraction is= "+sub);

        }

        else if(compare<0){

            double sub =  (doubleValue2 -  doubleValue1);

            System.out.println(doubleValue2+" is greater. \nAnswer after subtraction is= "+sub);

        }

        else{

            double sub =  (doubleValue1 -  doubleValue2);

            System.out.println(" Both are equal! \nAnswer after subtraction is= "+sub);

        }

    }

}

Answer after subtraction is= 0.4399999999999995

Example 2

import java.lang.Double;
import java.util.Scanner;

public class  DoubleCompareToMethodExample2 {
    public static void main(String[] args) {


        Double d1 = new Double("35");
        Scanner scanner= new Scanner(System.in);

        System.out.println("Enter your percentage");
        Double d2=scanner.nextDouble ();

        //compares two Double objects numerically
        int compare=d1.compareTo(d2);
        if(compare >= 0){
            System.out.println(" You are not eligible for the Exam.");
        }
