inner class
if a class is not declared public
then it is accessible only to members of the same package
constructor a class type whose instances are the values of the class type
class classname
{ // declarations of variables
// declarations of constructors
// declarations of other methods with public ones first
}
a unique name since somebody in the future might want to import the packages containing both classes and hence create a name clash 1 named package rather than the default package static or not any public class in other packages nested class Classes
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World!");
}
}
more than one interface
bold = mandatory
italic = non-terminal
normal font = optional
methods that are inherited from the class's superclass its own source file
reusability
modularity
0 or more methods to the methods it inherits from its superclass private or protected its members from access by other classes or objects using an access modifier an implements clause to declare that it contains methods for each of the operations specified by the interface A nested class whose instance exists within an instance of its enclosing class and has direct access to the instance members of its enclosing instance elements as follows:
class variables
instance variables
constructors
the most important public methods
methods that are simply used to access variables
private methods
1 class definition behaviour from its superclass implementation for all its instance methods unless the class is abstract Object class the internals of a computer system such as 'Record', 'Table', 'Data', 'Structure', or 'Information' several similar objects only one superclass create an instance of it a list of variables, called instance variables, corresponding to data that will be present in each instance data associated with each object a package private or protected
