Solve me first

Problem Statement

This is an introductory challenge. The purpose of this challenge is to give you a working I/O template in your preferred language. It includes scanning two integers from STDIN, calling a function, returning a value, and printing it to STDOUT.

The task is to scan two numbers from STDIN, and print the sum A+B on STDOUT. The code has already been provided for most of the popular languages. This is primarily for you to read and inspect how the IO is handled.

Note: The code has been saved in a template, which you can submit if you want. Or, you may try rewriting it and building it up from scratch.

Input Format
(This section specifies the Input Format.)
Given A and B on two different lines.

Output Format
(This section specifies the Output Format.)
An integer that denotes Sum (A+B)

Constraints
(This section tells what input you can expect. You can freely assume that the input will remain within the boundaries specified. As an example here given below, A and B will never be below 1 or above 1000.)
1≤A,B≤1000

Sample Input

2
3

Sample Output

5

The above sample should be taken seriously. The input will be 2 and 3 in two separate lines, and the output should be just one number, 5. You should not print any whitespace at the beginning of output (e.g. ” 5″ or “\n5”), unless specifically asked for. Also, printing any extra non-whitespace characters such as “The answer is: 5” will result in a Wrong Answer, as the judging is done using diff checker.

import java.util.*;
import java.text.*;

import java.util.regex.*;

public class Solution {


    static int solveMeFirst(int a, int b) {
        return a+b;
   }

   
 public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int _a;
        _a = in.nextInt();
        int _b;
        _b = in.nextInt();
        int sum;
        sum = solveMeFirst(_a, _b);
        System.out.println(sum);
   }
}
