In Java, a class is a type, similar to the built-in types int and boolean. Declaring a variable does not create an object. Explain the mechanism to create an object.

3) Static: Because main is static itself so, it can call only static variable/method.

The finally clause is used to provide the capability to execute code no matter whether ornot an exception is thrown or caught.

When we write try catch block, at that time we try block caught an exception in this case we must & should want to execute some peace of code at that time we write this code in finally block . finally block must & should be executed at the End

You dont need the "finally" clause. Leave it out altogether, and the same thing happens - the code will get executed anyway. The "finally" clause is irrelevant.

Java packages do not contain objects. This is so, because unlike classes, interfaces, and sub-packages, Java objects are instantiated entities, and do not always exist.

Neha Gupta

• Feb 17th, 2012

Objects. This is because package does contain interfaces like Serializable. Classes and other sub-packages or packages always fall under package.

Object class does fall under java.lang package but Objects are created when any concrete class is instantiated.

Hash code is nothing but byte code. The byte code produced in Java is independent of architecture. We can run this byte code in any platform. By this we can say that Java is platform independent.

In Java, object types (i.e., classes) must be explicitly constructed for initialization. Explain object construction. Then, state the name of the mechanism for object destruction, and explain in simple terms how it works.

Priya

• Mar 16th, 2012

In java Object destruction is automatically done by Garbage Collector which is provided y java run time system.

when ever the scope of the object is over then the memory which is allocated for that object is released by the garbage collector.The programmer no need to do anything explicitly.
