Writing your own classes in Java (implementing Card game)

Testing/demonstrating methods of the Card class:


public class TestCard {

	/**
	 * test the Card object
	 */
	public static void main(String[] args) {
		Card aceSpades = new Card("Spades", "A");
                // expect: Spades
		System.out.println(aceSpades.getSuit());
                // expect: A
		System.out.println(aceSpades.getValue());
                 // expect: 14              
		System.out.println(aceSpades.getNumericValue());
		
		Card fiveHearts = new Card("Hearts", "5");
                // expect: Hearts
		System.out.println(fiveHearts.getSuit());
                // expect: 5
		System.out.println(fiveHearts.getValue());
                // expect: 5
		System.out.println(fiveHearts.getNumericValue());
		
                //user-friendly printing of a card: implement toString
		System.out.println(aceSpades);
		System.out.println(fiveHearts);
                
		/*
                // this should cause the program to exit
		Card invalidValue = new Card("Hearts", "S");
		*/
		
		// Comparison of cards by value
                // expect: a value > 0
		System.out.println(aceSpades.compareTo(fiveHearts));
                // expect: a value < 0
		System.out.println(fiveHearts.compareTo(aceSpades));
                // expect: a value = 0
		System.out.println(aceSpades.compareTo(aceSpades));
		
	}
