代码如下:
import java.util.Scanner;


public class sum {
public static void main(String[]args){

int nextValue;

int sum=0;
Scanner kbInput = new Scanner(System.in);


kbInput.useDelimiter("\\s");

while(kbInput.hasNextInt())
{
nextValue = kbInput.nextInt();
sum += nextValue;
}
System.out.printf("Sum: %d",sum);
kbInput.close();

}

}

运行结果:
