알고리즘 3 (백준 알고리즘 - 입출력)

import java.util.Scanner;

public class Main {
public static void main(String[] args) {
	
	Scanner scanner = new Scanner(System.in);
	
	int A = scanner.nextInt();
	int B = scanner.nextInt();
	
	if(0<A && B<10) {
		int sum = A+B;
		System.out.println(sum);
	}
}
}

A B 입력받아서 더한 값 구해주기.
