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%
