  • Declaring Classes

     

     <!-- Declaring Classes -->  You've seen classes defined in the following way: 

    class MyClass {     //field, constructor, and method declarations } 

      This is a class declaration. The class body (the area between the braces) contains all the code that provides for the life cycle of the objects created from the class: constructors for initializing new objects, declarations for the fields that provide the state of the class and its objects, and methods to implement the behavior of the class and its objects. 
  • You can also add modifiers like public or private at the very beginning—so you can  see that the opening line of a class declaration can become quite complicated.  The modifiers public and private, which determine what other classes can access MyClass,  are discussed later in this  lesson.

  • In general, class declarations can include these components, in order: 

     
    1. Modifiers such as public, private, and a number of others that you will encounter later. 
     
    2. The class name, with the initial letter capitalized by convention. 
     
    3. The name of the class's parent (superclass), if any, preceded by the keyword extends. A class can only extend (subclass) one parent. 
    4. A comma-separated list of interfaces implemented by the class, if any, preceded by the keyword implements. A class can implement more than one interface. 
    5. The class body, surrounded by braces, {}.
