求和

import java.util.Scanner;

public class jin{
public static void main(String[]args){
//从键盘读取若干整数并求和输出
int nextValue;

    int sum=0;
    Scanner sr = new Scanner(System.in);
  //设置空格为数据的分隔符
    sr.useDelimiter("\\s");
    
    while(sr.hasNextInt())   //判断有没有int型的输入
    {
    nextValue = sr.nextInt();//读取从键盘输入的整数
    sum += nextValue;
    }
    
    //System.out.println("sum:"+sum);
    System.out.printf("Sum: %d",sum);
    sr.close();
    
    

}
