Java history is interesting to know. The history of java starts from Green Team. Java team members (also known as Green Team), initiated a revolutionary task to develop a language for digital devices such as set-top boxes, televisions etc.

A package defines the scope of the declarations it contains and may be separated into an interface package and an implementation package.
C++ provides several types of scopes: global, file, class, and block. We can also create a package scope using a namespace declaration:
namespace NAME { DECLARATION ... }

What is the difference between an Abstract class and Interface?


1. Abstract classes may have some executable methods and methods left unimplemented. Interfaces contain no implementation code.
2. An class can implement any number of interfaces, but subclass at most one abstract class.
3. An abstract class can have nonabstract methods. All methods of an interface are abstract.
4. An abstract class can have instance variables. An interface cannot.
5. An abstract class can define constructor. An interface cannot.
6. An abstract class can have any visibility: public, protected, private or none (package). An interface's visibility must be public or none (package).
7. An abstract class inherits from Object and includes methods such as clone() and equals().

What is a user defined exception?


User-defined exceptions may be implemented by
• defining a class to respond to the exception and
• embedding a throw statement in the try block where the exception can occur or declaring that the method throws the exception (to another method where it is handled).
The developer can define a new exception by deriving it from the Exception class as follows:
public class MyException extends Exception {
/* class definition of constructors (but NOT the exception handling code) goes here public MyException() {
super();
}
public MyException( String errorMessage ) {
super( errorMessage );
}
}
The throw statement is used to signal the occurance of the exception within a try block. Often, exceptions are instantiated in the same statement in which they are thrown using the syntax.
throw new MyException("I threw my own exception.") To handle the exception within the method where it is thrown, a catch statement that handles MyException, must follow the try block.
If the developer does not want to handle the exception in the method itself, the method must pass the exception using the syntax:
public myMethodName() throws MyException
