Class GameDie

java.lang.Object
GameDie
public class GameDie extends Object
A GameDie object represents a single game die. It has a set number of sides, each numbered from 1 to the number of sides, and it can be rolled, which results in a number between 1 and the number of sides. Adapted from Astrachan's "A Computer Science Tapestry" 2nd edition, pp. 214, 217. Compile using: javac GameDie.java (but cannot execute by "itself" - no main method!)

    Constructor
    Description
    GameDie()
    construct a new die with the default number of sides, 6, and an initial top value of 1
    GameDie​(int desiredNumSides)
    construct a new die with the user-specified number of sides and an initial top value of 1

    Modifier and Type
    Method
    Description
    int
    getCurrTop()
    return the die's current top value
    int
    getNumSides()
    return the calling die's number of sides
    int
    roll()
    expects nothing, computes a pseudo-random int in [1, num_sides], changes currTop of the calling GameDie to that computed value, and also returns that computed value as the result of this call to roll
