java实现a+b的多重输入

import java.util.Scanner;
public class hello {
    public static void main(String[] args)
    {
        Scanner cin = new Scanner(System.in);
                {
                    while(cin.hasNextInt())
                    {
                        int a = cin.nextInt();
                        int b = cin.nextInt();
                        System.out.println(a+b);
                    }
                }
    }
}
