About Class Or Static Variable In Java Programming

In this tutorials we will discussed more about variables in java programming of Class Or Static. 

Types of variables:

Class Or Static 
Instance 
Local
Parameters Or Arguments 

What we need before start the code, I'm using as mention below and already installed in my system:
1. JDK1.6 or +
2. Eclipse
3. Windows OS
4. Basic knowledge of java

Let's start:

Verify the JDK installation

Open the command prompt and verify the java installation
Type the 
C:\>javac -version
javac 1.7.0_25

C:\>java -version
java version "1.7.0_25"
Java(TM) SE Runtime Environment (build 1.7.0_25-b17)
Java HotSpot(TM) Client VM (build 23.25-b01, mixed mode, sharing)

Now java installation got verified, as installed JDK1.7.0_25

Verify the Eclipse installation

Go the the installation directory of eclipse and click on the eclipse.exe

e.g C:\eclipse\eclipse-java-mars-1-win32\eclipse\eclipse.exe

Create the new java project in Eclipse

Open the eclipse
File
New
Java project
Type the project name: Variables_In_Java_Programming
Next
Finish

Create the ClassOrStaticVariablesInJava.java file

Right click on the src created under project Variables_In_Java_Programming
New
Class
Type the name of class: ClassOrStaticVariablesInJava
Type the package name: com.variables.atozexamples
Finish

package com.variables.atozexamples;

public class ClassOrStaticVariablesInJava {

       // Class or Static variable

       public static int iClassOrStaticVarible = 1;

       // Class or Static variable as final, we can't change the value and name

       // must be in capital

       public static final int I_CLASS_OR_STATIC_FINAL_VARIBLE = 200;

       public ClassOrStaticVariablesInJava() {

              // TODO Auto-generated constructor stub

       }

       public static void main(String[] args) {

              // Class level access

              System.out.println("Output of Class or Static Variable value = " + I_CLASS_OR_STATIC_FINAL_VARIBLE);

              System.out.println("Output of Class or Static Variable by obj value =" + iClassOrStaticVarible);

              // New object creation of ClassOrStaticVariablesInJava

              ClassOrStaticVariablesInJava obj = new ClassOrStaticVariablesInJava();

              // Calling with obj

              System.out.println("Output of Class or Static Variable by obj value =" + obj.iClassOrStaticVarible);

              System.out.println("Output of Class or Static Variable by obj value =" + obj.I_CLASS_OR_STATIC_FINAL_VARIBLE);

             

              iClassOrStaticVarible = 300;

             

              System.out.println("Output of Class or Static Variable by obj value =" + obj.iClassOrStaticVarible);

             

              System.out.println("Output of Class or Static Variable by obj value =" + iClassOrStaticVarible);

       }

}
