Java is most suitable for creating Enterprise Applications for its flexibility and control. JAVA is used to create wide range of application with an extensive functionality. Java application development can be used for creating Games or corporate application. Java development allows users to take benefit of many Smartphone features, like GPS and Bluetooth and integrate those features flawlessly with already-existing BlackBerry apps such as the address book, calendar, and maps features. The only disadvantage is that Java provides huge functionality and that requires some expert skills to take advantages and integrating JAVA application.

Choosing the right Java developer is always tough task when you are creating broad applications with a large amount of functionality. One feature of Java is portability, which means that programs written in the Java language must run similarly on any supported platform.

Sun Microsystems officially licenses the Java Standard Edition platform for Linux, Mac OS X, and Solaris. Java Programs have a reputation for being slower and requiring more memory than the programs written in some other languages. Java syntax is largely derived from C++. Unlike C++, that combines the syntax for structured, generic, and object-oriented programming.

Java is a programming technology developed by Sun Microsystems. Java is an object-oriented language. Java can be used for web development.

Java is platform independent. The java code is compiled into a bytecode that can be run on a Java Virtual Machine(JVM). So Java code will run on any system that has a JVM installed in it. Java is robust, flexible and scalable. It can also be used to communicate with legacy systems.

The simplest form of a java program is as follows:

// Java program 1

public class Welcome1{

public static void main (String args[])

{

System.out.println ( “Welcom”);

}

}

In the above example;

// denotes that the statement is a comment and it not considered for programming.

The statement public class welcome1 is used to define the class. Java programs consist of classes defined like this.

The statement public static void main is used to define program building block. Every java program consist of a main function.

The statement System,out.println is used to produce the output. It gives instructions to the computer to print the String as an output.

Save the above program as Welcome1.java in the java Bin Directory.

Example C:javabin

The next step is to create the .class file by compiling the .java file.

In the dos prompt,

Type javac Welcome1.java and press enter.

It will produce a .class filee.

The final step is to run the class file. Type java Welcome1 to execute the .class file.

You will receive the desired output.
