Rolling a 6 sided die

[cowboyjeff05]

the question is 1) build a Die class (6 sided). Then create a driver that tests your class. Start with one die in your driver then add a second die and notify the user and count when he or she rolls 7, 11, or a double. When the user is done rolling, output the results of the session.

Create a child class from the Die class called MultisidedDie. This die should allow the programmer using the class to decide how many sides the die has.


so far i have

import java.util.Random;
 
public class DiceTest
{
  int num;
  int sides;
 
  Dice()
  {
    num = 1;
    sides = 6;
  }
 
  Dice(int number)
  {
    num = 1;
    sides = 6;
    if(number > 1)
    {
      num = number;
    }
  }
 
  Dice(int number, int num_sides)
  {
    num = 1;
    sides = num_sides;
    if(number > 1)
    {
      num = number;
    }
  }
 
  int roll()
  {
    java.util.Random r = new java.util.Random();
    int sum = 0;
    for(int i = 0; i < num; i++)
    {
      sum += r.nextInt(sides)+1;
    }
    return sum;
  }
}

however when i compile i get a "invalid method declaration; return type required" on line 8,14,24....any advice or help woud be greatly aprecciated!!!

You have named your class 'DiceTest'; your constructors must have that same name.

kind regards,

Your code would also be more efficient if, instead of creating a new Random object every time you call roll(), you had a private Random object in the class dedicated to generating your random rolls.

In addition, what purpose does num serve? Should that be a class member or a function parameter?

JosAH's suggestion will get your code compiling and working, but consider mine if you'd like to make your code a bit 'cleaner'.
