Java Double sum() Method

The sum() method of Double class returns the sum of two double arguments same as the operation performed by ‘+’ operator.

Syntax:

Parameters:

a– the first argument passed

b– the second argument passed

Return Value:

The sum() method returns the sum of a and b.

Example 1

  import java.util.Scanner;      public class Double_sumMethodExample1 {        public static void main(String[] args) {            Scanner scanner= new Scanner(System.in);            System.out.print(“Enter first number: “);            Float f1=scanner.nextFloat();            System.out.print(“Enter second number: “);            Float f2=scanner.nextFloat();            Float f3=Float.sum(f1,f2);            System.out.print(“Enter third number: “);            Float f4=scanner.nextFloat();            System.out.println(“Sum = “+Float.sum(f3,f4));        }    }  

Output:

Enter first number: 67  Enter second number: 98  Enter third number: -98  Sum = 67.0

Example 2

  import java.util.Scanner;    public class Double_sumMethodExample2 {        public static void main(String[] args) {            Scanner scanner= new Scanner(System.in);            Double a[] =new Double[6];            System.out.println(“Enter your Marks of following subjects”);            System.out.print(“English : “);            a[0] = scanner.nextDouble();            System.out.print(“Maths : “);            a[1] = scanner.nextDouble();            System.out.print(“Science : “);            a[2] = scanner.nextDouble();            System.out.print(“S.St : “);            a[3] = scanner.nextDouble();            System.out.print(“Hindi : “);            a[4] = scanner.nextDouble();            System.out.print(“Computer : “);            a[5] = scanner.nextDouble();            Double d1=0.0;            for (int i = 0; i < 5; i++) {                d1 = Double.sum(a[i], a[i + 1]);                a[i + 1] = d1;                      }            Double d2= (d1)/6;            System.out.println(“You got “+d2+”%”);        }}  

Output:

Enter your Marks of following subjects  English : 87  Maths : 98  Science : 67  S.St : 87  Hindi : 56  Computer : 45  You got 73.33333333333333%
