// This example is like StaticTest.java, except this time we
// use objects to make our code simpler.
//

class Character {

   // properties of the class...

   public String name;
   public String favouriteColour;
   public int    favouriteNumber;
  
   // constructor of the class...
 
   public Character(String aName, String aColour, int aNumber)
   {
      name            = aName;
      favouriteColour = aColour;
      favouriteNumber = aNumber;
   }

   public void displayMe()
   {
      System.out.println("Hello, my name is " + name);
      System.out.println("my favourite colour is " + favouriteColour);
      System.out.println("and my favourite number is " + favouriteNumber);
   }
} 

class StaticTest2
{ 
   public static void main(String[] args)
   {
      Character f = new Character("Fred Flintstone", "blue", 42);
   }
}

// QUESTIONS:
//
// (1) Add code to the StaticTest2 class to construct two
// new Character objects, one to represent "Barney Rubble"
// and the other to represent "Wilma Flintstone".  Make sure
// that the values of the properties are set appropriately.
// 
// (2) Add some code to the main method to call Fred
// Flintstone's displayMe method.
 
// HINT: Calling a non-static method.
// 
// (3) Add some code to the main method to print out Barney
// Rubble's favourite colour WITHOUT using Barney Rubble's
// displayMe method.
 
// HINT: Accessing a non-static property.
// 
// (4) Why is it better to have a Character class for a
// general character rather than a class for each character?
//
// HINT: Imagine that you had 100 characters to consider.
// 
// (5) Under what circumstances would it be better to have a
// separate class for each character, rather than a separate
// object for each character?
