Tips in Download and Installation

Welcome new comers for JAVA. In this post I’m trying to give some basic ideas for you at the first level. I’m sure you will bump into more thrilling experiences in future.

What is JAVA?

JAVA is a Platform Independent Language; therefore you can write & execute the program in any operating system (Anywhere – Windows, UNIX, Linux etc)

How to download JAVA?

If you are a Windows user before downloading JAVA first find out whether the system is 32 bit or 64 bit

There are some ways to find out it

• Start >Run>dxdiag

Under SYSTEM tab, System Operation the version is found can be found in Operating System:

• Start>Run>System Information

        The bit version can be found at SYSTEM TYPE

  
  
  
  
  Here is the step to download JAVA :-
  

http://www.oracle.com > Downloads >JAVA for Developers >JAVA Platform >

& then select the version you need.

If you have a problem about the version that you must download, refer

A bit old link, but it really helped me personally.

Then install JAVA to your PC

How to check the installed JAVA version

Here is a simple program for Windows users to check whether they have installed the correct version

class Bitversion

{

 public static void main(String args[])

{

System.out.println("version ="+ System.getProperty("sun.arch.data.model"));

}

}

Setting the PATH

It is recommended to set the path initially before starting your work.

At the Command Prompt, you have to set the path

PATH = C:\Program Files\JAVA\jdk1.7.0_05\bin

But this temporary you have to set it again & again

.

To set the path permanent follow the steps below

Control Panel> System>Advanced>Environmental Variables>System Variables>Path>edit

In var value add the location of your JDK bin folder

(Do not delete the things inside add a semi colon [ ; ] then put the address beside it)

Welcome to JAVA people :)
