Polymorphism means any forms. In OOPS, it refers to the capability of objects to react differently to the same method. Polymorphism can be implemented in the Java language in the form of multiple methods having the same name. Java code uses a late-binding technique to support polymorphism; the method to be invoked is decided at runtime.

Both provide key-value access to data. The Hashtable is one of the original collection classes in Java. HashMap is part of the new Collections Framework, added with Java 2, v1.2. The key difference between the two is that access to the Hashtable is synchronized on the table while access to the HashMap isn't. You can add it, but it isn't there by default.

Garbage collection is one of the most important feature of Java. Garbage collection is also called automatic memory management as JVM automatically removes the unused variables/objects (value is null) from the memory. User program can�t directly free the object from memory, instead it is the job of the garbage collector to automatically free the objects that are no longer referenced by a program.

The "JDK" is the Java Development Kit. i.e., the JDK is bundle of software that you can use to develop Java based software. The "JRE" is the Java Runtime Environment. i.e., the JRE is an implementation of the Java Virtual Machine which actually executes Java programs.

Synchronization is a process of controlling the access of shared resources by the multiple threads in such a manner that only one thread can access one resource at a time. In non synchronized multithreaded application, it is possible for one thread to modify a shared object while another thread is in the process of using or updating the object's value. Synchronization prevents such type of data corruption.

Serialization is a way of flattening, pickling, sizzling, serializing, or freeze-drying Objects so that they can be stored on disk, and later read back and reconstituted, with all the links between Objects intact Object serialization is the process of saving an object's state to a sequence of bytes, as well as the process of rebuilding those bytes into a live object at some future time

Java programming language was primarily developed to deal with embedded applications. But with the introduction of Swing and other user interface utilities to Java, it made its mark in desktop applications too. Now the trend is to use Java technology in developing large web and enterprise applications. Java is more focused on web then desktop applications. But, in this article, we are going to discuss how useful Java is as a development technology for stand alone desktop application development in present scenario.

This tutorial compares .NET and J2EE, discussing various features of both the technolgoies and summarising when and where these technologies are suitable to use for entriprise application.
