scanner cannot read last int from a string

    if (diceValues == null || diceValues.length() == 0) return 0;
    int temp;
    int val = 0;
    Scanner scanner = new Scanner(diceValues);
    while (scanner.hasNext()) {
        temp = scanner.useDelimiter(" ").nextInt();
        if (temp == 1) val += 100;
        if (temp == 5) val += 50;
    }

diceValue is a string like this: "1 2 3 4 5", and the scanner always skips the last number. So the int val(value) always smaller than it should be.

I think your code has no problem.I ran it this way and it returned me value 150.

import java.util.Scanner;
public class Prog1 
{
    public static void main(String[] args){
        Prog1 p =new Prog1();
        int value = p.mymethod();
        System.out.println(value);
    }
    public int mymethod()
    {
        String diceValues = "1 2 3 4 5";
        if (diceValues == null || diceValues.length() == 0) return 0;
        int temp;
        int val = 0;
        Scanner scanner = new Scanner(diceValues);
        while (scanner.hasNext()) {
        temp = scanner.useDelimiter(" ").nextInt();
            if (temp == 1) val += 100;
            if (temp == 5) val += 50;
        }
        return val;
    }
