###Daily Programmer - July 10th 2013 User input in the form of 'ndm' where n is the number of dice, and m is the number of faces.

DiceRoll.java

import java.util.Scanner;

public class DiceRoll {

    public static void main(String[] args) {
        // Get the java console scanner. Allows the user to type into the console.
        Scanner s = new Scanner(System.in);
        // Pull the contents from what the user said. Split the array at the "d".
        // The input will look like ex: 4d10
        // Returns 4, 10 to the String array 'in'.
        String[] in = s.next().split("d");
        // We are parsing the ints so each iteration through the for loop won't
        // reparse them.
        int[] val = { Integer.parseInt(in[0]), Integer.parseInt(in[1]) };
        // Loop through the number of dice "val[0]" and then print what the dice roll
        // was based on how many faces the dice has "val[1]".
        for(int i=0; i < val[0]; i++) {
            System.out.print((int)(Math.random() * val[1] + 1) + "\t");
        }
    }
