Java Introduction and Environment Setup

Hello this is the my first Post in this blog. This post about programming basic. This is based on java programming language. You need to setup the java environment for working with java. So these things you need to download and install.

• Java JDK
• Netbeans IDE

You need to download the Java SE(Java Standard Edition) package and download the java JDK according to the your system. These instalation worked with windows OS. Now you have lot of quesions isn't it ? 

What is Java ? 

Java is a high-level programming language originally developed by Sun Microsystems and released in 1995. Java runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX.

 What is JDK ?

The Java Development Kit (JDK) is a software development environment used for developing Java applications and applets. It includes the Java Runtime Environment (JRE), an interpreter/loader (java), a compiler (javac), an archiver (jar), a documentation generator (javadoc) and other tools needed in Java development.

Simply JDK need for developing java program. So think like this, when you speak in english with a person who don't know english. So he can not understand what you'r tolking. So if you talking with computer you have to teach a language to computer then that teaching part done by jdk. After installed the jdk computer know what you'r talking.

What is NetBeans ?

 NetBeans IDE is an open-source integrated development environment for developing programmes. Using this IDE you can write codes easily. You also can write programmes without using IDE. But Using the IDE there are many advantages. You will feel that later. 

First Java programme

Then Click the File->New Project

 Then Click Java-> Java Application-> Next

Project Name: Give an any name you want. Then Hit Finish.
