If the method is labeled private, the method can only be used in the definition of another method of the same class. Normal good programming practices require that all instance variables be private and typically most methods be public. Create a class named Appointment that contains instance ...
even if they are declared private. Static nested classes do not have access to other members of the enclosing class. As a member of theOuterClass, a nested class can be declaredprivate,public,protected, orpackage private. (Recall

1. Difference between the private and final method in Java A private method is not visible outside the class they are declared, they are virtually final because you cannot override them. Whilefinal methodsare visible outside the class, you can call them outside the class they are declared, ...
Now it’s time to shift gears and talk about the Java Application Programming Interface (API), the collection of classes that comes with every Java implementation. The Java API encompasses all the public methods and variables in the classes that make up the core Java packages. Table 9.1 lists...
