Java Double compare() Method

The compare() method of Java Double class compares two specified double values.

Syntax

Parameters

Two parameters-

d1- The first double to be compared.

d2- The second double to be compared.

Return value

This method will return value –

zero, if d1 is numerically equal to d2.
less than zero, if d1 is numerically less than d2.
greater than zero, if d1 is numerically greater than
d2.

Example 1

  public class DoubleCompareMethodExample1{        private Double doubleValue1;         private Float doubleValue2;        public static void main(String[] args) {            Double doubleValue1 = new Double(“10.56”);            Double doubleValue2 = new Double(“10″);              double compare=Double.compare(doubleValue1, doubleValue2);            if(compare > 0){                double sub =  (doubleValue1 – doubleValue2);                System.out.println(doubleValue1 +” is greater. nDifference is= “+sub);            }                else if(compare<0){                double sub =  (doubleValue2 – doubleValue1);                System.out.println(doubleValue2 +” is greater. n” + “Difference is= “+sub);            }            else{                double sub =  (doubleValue1 – doubleValue2);                System.out.println(” Both are equal! nAnswer after subtraction is= “+sub);            }        }    }  

Test it Now

Output:

10.56 is greater.  Difference is= 0.5600000000000005.

Example 2

  import java.lang.Double;      public class DoubleCompareMethodExample2 {        public static void main(String[] args) {              Double double1 = new Double (“10″);                        int compare= Double.compare(double1 );            if(compare > 0){                System.out.println(f1+” is greater .”);          }            else if(compare<0){                System.out.println(f1+” is smaller .”);          }          else{                System.out.println(” Both are equal! “);          }      }  }  

Test it Now

Output:

Error:(13, 26) java: method compare in class java.lang.Double cannot be applied to given types;    required: double,double    found: java.lang.Double    reason: actual and formal argument lists differ in length

Example 3

  import java.lang.Double;  import java.util.Scanner;    public class  DoubleCompareMethodExample3 {      public static void main(String[] args) {              Double d1 = new Double(“24000”);          Scanner scanner= new Scanner(System.in);            System.out.println(“Enter your Family income”);          Double d2 = scanner.nextDouble ();                      int compare = Double.compare(d1,d2);          if(compare >= 0){              System.out.println(” You are eligible for the subsidy .”);          }            else{              System.out.println(“Sorry, You are not eligible for the subsidy.”);          }      }}  

Test it Now

Output:

Enter your Family income  45000  Sorry, You are not eligible for the subsidy
