import java.util.Scanner;

public class Main {
public static void main(String[] args) {
    int nextValue;
    int sum=0;
    Scanner kbInput = new Scanner(System.in);
    kbInput.useDelimiter("\\s");    //指定空格为分隔符
    while(kbInput.hasNextInt()){    //判断有没有整数可读
        nextValue = kbInput.nextInt();
        sum+=nextValue;
    }
    System.out.println("sum:"+sum);
    System.out.printf("Sum:%d",sum);
    kbInput.close();                //关闭流对象
}
}

 运行结果
