백준 / JAVA / 1001번 / A-B

 

import java.util.*;

public class Main{
    public static void main(String[] args){
        Scanner sc = new Scanner(System.in);
        
        int n1 = sc.nextInt();
        int n2 = sc.nextInt();
        
        System.out.print(n1-n2);
    }
}

1000번과 같은 형식이다.

이것도 BufferedReader로 해본다면

 

import java.io.*;

public class Main {

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

		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		StringTokenizer st = new StringTokenizer(br.readLine());		
		
		int num1 = Integer.parseInt(st.nextToken());
		int num2 = Integer.parseInt(st.nextToken());
		
		System.out.println(num1-num2);
    }
}
