About Local Variables in java programming

In this tutorials we will discussed more about variables in java programming of Local Variables

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 LocalVariableInJava.java file


Right click on the src created under project Variables_In_Java_Programming

New
Class
Type the name of class: LocalVariableInJava
Type the package name: com.variables.atozexamples
Finish

package com.variables.atozexamples;

public class LocalVariableInJava {

       public LocalVariableInJava() {
              // TODO Auto-generated constructor stub
       }

       public static void print() {
              int a = 50, b = 55, c = a + b;

              int a1_$ = 50;
              int b1_$ = 50;
              int c1_$ = a1_$ + b1_$;

              System.out.println("Output of print() method variable a = " + a + ", b = "                + b + " and c =" + c);
              System.out.println("Result of c =" + c1_$);
       }

       public static void main(String[] args) {
              // Local Variables
              int a = 10;
              int b = 20;
              int c = a + b;
              System.out.println("Output of main() method variable a = " + a + ", b = " +               b + " and c =" + c);

              // Calling the static print method
              print();

       }
}
