① BufferedWriter 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=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");
        }

        br.close();
        bw.flush();
        bw.close();
    }
}

 

② StringBuilder 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));
        StringBuilder sb = new StringBuilder();

        int T = Integer.parseInt(br.readLine());
        StringTokenizer st;
        for(int i=1; i <= T; i++){
            st = new StringTokenizer(br.readLine()," ");
            int a = Integer.parseInt(st.nextToken());
            int b = Integer.parseInt(st.nextToken());

            sb.append("Case #"+i+": ");
            sb.append(a+b);
            sb.append("\n");
        }
        System.out.println(sb);
        br.close();

    }
}
