<풀어보오자>

import java.util.Scanner;

public class Main {
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		int T = sc.nextInt();
		
		for (int i = 1; i<=T; i++) {
			int a = sc.nextInt();
			int b = sc.nextInt();
			
			System.out.println("Case #" + i + ": "+ (a+b));
		}
		}
	}

간단한 출력문제라 간단하게 해결!!

어제 공부한 BufferedReader/Writer로도 한번 해볼께요~~

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

public class Solution11021_bf {
	public static void main (String[] args) throws IOException {
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(System.out));
		StringTokenizer st;
		int T = Integer.parseInt(br.readLine());
		
		for (int i=1; i<=T; i++) {
			
			st = new StringTokenizer(br.readLine());
			
			int a = Integer.parseInt(st.nextToken());
			int b = Integer.parseInt(st.nextToken());
			
			bw.write("Case #"+ i + ": " +  +(a+b) + "\n");
		}
		bw.close();
	}
}

아직은 버퍼 쓰기 좀 어색하네요 ㅎㅎㅎ import도 많구....

그래도 출력이 빠르다고 하니 계속 시도는 해보겠습니다
