 1 import java.util.*;
 2 
 3 public class Main {
 4 
 5     public static void main(String[] args) {
 6         Scanner reader=new Scanner(System.in);
 7         while(reader.hasNext()) {
 8             int A=reader.nextInt();
 9             int B=reader.nextInt();
10             System.out.println(A+B);
11         }
12     }
13 
14 }

　　此题是需要不断输入输出的，而且while(true)这样写是不对的，系统默认陷入死循环！而用hasNext()系统默认是停止等待输入。
