Buffer를 이용하여 입출력 계산. StringTokenizer도 이용

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.StringTokenizer;

public class Main {
    public static void main(String[] args) throws IOException {

        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

        String str = br.readLine();
        StringTokenizer st = new StringTokenizer(str, " ");

        int a = Integer.parseInt(st.nextToken());
        int b = Integer.parseInt(st.nextToken());

        System.out.println(a+b);
    }
}
