import java.util.*;

public class Main {

    public static void main(String[] args) {
        Scanner reader=new Scanner(System.in);
        while(reader.hasNext()) {
            int A=reader.nextInt();
            int B=reader.nextInt();
            System.out.println(A+B);
        }
    }

}

　　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。
