[Java] 백준 10951: A+B - 4

import java.util.*; public class Main { public static void main(String[] args) { Scanner sc = new Scanner(System.in); while(sc.hasNextInt()) { int a = sc.nextInt(); int b = sc.nextInt(); System.out.println(a+b); } } } Scanner의 hasNextInt 메소드를 이용하여 더이상 입력받을 데이터가 없으면 종료하게끔 문제를 해결하였다.

[Java] 백준 10952: A+B - 5

import java.util.*; public class Main { public static void main(String[] args) { Scanner sc = new Scanner(System.in); while(true) { int a = sc.nextInt(); int b = sc.nextInt(); if(a+b==0) { break; } System.out.println(a+b); } } } 0 0 이 나올때까지 무한반복이므로 while 무한루프 사용하여 문제를 해결하였음.
