D.9. Introduction to Random-Number Generation
We now take a brief diversion into a popular type of programming application—simulation and game playing. In this and the next section, we develop a nicely structured game-playing program with multiple methods. The program uses most of the control statements presented thus far in the appendices and introduces several new programming concepts.
Random numbers can be introduced in a program via an object of class Random(package java.util) or via the static method random of class Math. A Random object can produce random boolean, byte, float, double, int, long and Gaussian values, whereas Math method random can produce only double values in the range 0.0 ≤ x < 1.0, where x is the value returned by method ...
