Question description

Read two double types of numbers greater than or equal to 0 through the keyboard, find their sum, and output the two numbers and their sum in an independent line in the specified format.

Enter a description

Two non-negative double types, separated by spaces in the middle

Output description

Output in separate lines:
a+b=sum
Among them, a, b, sum all retain two decimal places

Enter sample

33.245 10.1

Output sample

33.25+10.10=43.35

Program code

import java.util.Scanner;
public class Main{
    public static void main(String[] args){
        Scanner scanner = new Scanner(System.in);
        double a, b, sum;
        a = scanner.nextDouble();
        b = scanner.nextDouble();
        sum = a + b;
        System.out.printf("%.2f+%.2f=%.2f", a, b, sum);
    }
