Other access modifiers are abstract and final; we won’t deal with those in this book. u The keyword class. u A user identifier for the name of the class; Book is used in the example. The braces enclose the body of the class. In general, the body will include the declaration of the following: u Static variables (class variables); there will be one copy for the entire class—all objects will share that one copy. A class variable is declared using the word static. If we omit the word static, the variable is instance.
It cannot; it can hold only a reference to a Book object. ) However, where the distinction (between an object and a reference to the object) does not matter, we will speak as if b holds a Book object. inStock However, we can do so from outside the class only if the fields are declared public. We will see later how to access the fields indirectly when they are declared private. When an object is created, unless we say otherwise, its instance fields are initialized as follows: u Numeric fields are set to 0.
We will see later how to access the fields indirectly when they are declared private. When an object is created, unless we say otherwise, its instance fields are initialized as follows: u Numeric fields are set to 0. u Character fields are set to '\0' (Unicode '\u0000', to be precise). u Boolean fields are set to false. u Object fields are set to null. author (of type String) is set to null; remember that String is an object type. title (of type String) is set to null. 0. pages (of type int) is set to 0.
