The class Random. The Java class library provides a class called Random that implements a random number generator.

The class Random. The Java class library provides a class called Random that implements a random number generator. You will use it to help shuffle the deck. To use Random, you must put the following line at the start of your program.

Note that java and util are in lower case, Random begins with an upper case letter, and the line ends with a semicolon. The import statement obtains something from the Java library.

     You need only Random's constructor and its method nextInt. The constructor call new Random() returns a new instance of the class Random. If r is an instance of Random, then r.nextInt()returns a randomly generated int. It may be negative, and it may have a large absolute value. 

     For this program, you will need small positive random int's. You can get these by using the Java expression Math.abs(r.nextInt()) % m, where m returns a positive int greater than 0. The expression will return a random int greater than equal to 0 You must use this source code; you must not modify or extend Card in any way. Here is a short description of Card's public methods.
