How to Start Java Programming

Java is an Object oriented programming. you can easily start your java programming. I am going to provide some simple steps to create java program. without wasting your precious time on internet or books.

First Of All We are going to set up our computer to make and run java program.

so First of All download JDK (java development kit) from http://www.oracle.com/technetwork/java/javase/downloads/index.html

and Install it by double click on it.

After that

to be ensure java has installed successfully.
by default all java file goes into
C:\\program files\java\
There are two folder will be there
if(jdk 7) latest version of java technology

jdk1.7...
jre 7

then open jdk1.7 /bin then you will get all tools related to Java development.
we want access all /bin folder tools every where on my computer so I am going to set path
on my computer.

We will develop java program with notepad or any editor and cmd as a beginner.

After Installation
Set path

go to run and type -- sysdm.cpl
then click on Advance system security
then click on Advance Tab
then click on Environment variable
then you will get two variables

User Variable
System Variable

Go For User Variable and Click New
Variable Name -  path
Variable value - C:\Program Files\Java\jdk1.7.0_04\bin

and click ok

after that open a new cmd (if old cmd is open then close that)

and type javac

If Some switch open and Printing like this then you are now enable to compile and run ur program your computer
