① StringTokenizer 사용

import java.io.*;
import java.util.StringTokenizer;

public class Main {
    public static void main(String[] args) throws IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(System.out));

        int T = Integer.parseInt(br.readLine());

        StringTokenizer st;

        for(int i=0; i<T; i++){
            st  = new StringTokenizer(br.readLine(), " "); // " "로 자르기
            bw.write(Integer.parseInt(st.nextToken())+ Integer.parseInt(st.nextToken()) + "\n");
        }

        br.close();

        bw.flush(); // 버퍼 비우기
        bw.close(); // 버퍼 닫기
    }
}

 

② split 사용

import java.io.*;
import java.util.StringTokenizer;

public class Main {
    public static void main(String[] args) throws IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(System.out));

        int T = Integer.parseInt(br.readLine());

        for(int i=0; i<T; i++){
            String s = br.readLine();
            int a = Integer.parseInt(s.split(" ")[0]);
            int b = Integer.parseInt(s.split(" ")[1]);
            bw.write(a + b +"\n");
        }

        br.close();

        bw.flush(); // 버퍼 비우기
        bw.close(); // 버퍼 닫기
    }
}
