3.4.1 Declaring an Account Constructor for Custom Object Initialization
When you declare a class, you can provide your own constructor to specify custom initialization for objects of your class. For example, you might want to specify a name for an Account
object when the object is created, as in line 10 of Fig. 3.6:
Account account1 = new Account("Jane Green");
In this case, the String
argument "Jane Green"
is passed to the Account
object’s constructor and used to initialize the name
instance variable. The preceding statement requires that the class provide a constructor that takes only a String
parameter. Figure 3.5 contains a modified Account
class with such a constructor.
