Dear Sir, I have gone through many training sessions about JAVA from Youtube or INTERNET, but i could not get the clear picture about the Java, but I got the very clear picture from your trainings sessions. Your teaching is absolutely fantastic Sir. No one can explain this much in-depth level about each and every concepts. I am feeling more happy that i am understanding java clearly. All because of your outstanding teaching only. Thank you so much your wonderful service to students. Kindly continue your invaluable service. Thanks again Sir.

Class Notes:
Selenium Class 6: Introduction to Java

i) Introducing Java Programming Language

ii) Java Environment Setup

iii) Java Program Structure/Java Syntax

i) Introducing Java Programming Language

> Java Programming Language was developed by Sun Microsystems in 1995, Now it is
subsidiary of Oracle corporation.

> Java is an Object Oriented Programming Language, In Java everything is object, Java
can be easily extended since it is based on the object model.

> Java is a Platform independent language, It can be compiled and interpreted.

> Java is Simple easy to learn and implement.

> Java is Securable, Using Java we can develop virus free and tamper free systems.

Usage of Java

> Developing Desktop Applications (Ex: Acrobat Reader)

> Developing web Applications

> Developing Enterprise Application (Ex: Banking, Insurance Applications etc...)

> Developing Mobile Applications

> Developing Embedded Systems.

> Smart Cards

> Games software etc...

> Test Automation

Java Syntax

> Java is case sensitive language

> First letter of Class Name should be in Upper case

> Method names should start with lower case letter.

> Java program file name should exactly match with class name.

> Java Program execution starts from main method, which is mandatory in every Java program.

> Every Statement should end with semi colon symbol.

> Code blocks enclosed with {}

ii) Java Environment Setup

Steps:

> Download Java Software (JDK) and Install.

> Set Environment Variable (Path Variable).

> Download Eclipse IDE and Extract.

In Computer Programming we have Three steps

i) Writing a Program.

ii) Compiling the Program

iii) Run /Execute the Program

Step 1: Writing a Program.

public class Sample{
public static void main(String [] args) {
System.out.println ("Hello Java World");
}
}

Step 2: Compiling the Program

Change to Java program file directory.

Type javac Sample.java

(* it creates Java class file)

Step 3: Run /Execute the Java program

Type java Sample

In Test Automation using Selenium, we use an Integrated Development Environment (IDE) like
Eclipse IDE.

> Eclipse IDE (Integrated Development Environment)

> Eclipse IDE is a platform to create and Run /execute programs like Java, Perl, Python,
Ruby, PHP etc...

> Eclipse IDE is open source (eclipse Public License)

It provides Editor, help for Syntax, context help, auto compilation, debugging etc....

Download Eclipse IDE and Extract.

Write and Execute a Java program using Eclipse IDE

Steps:

> Launch Eclipse IDE

> Create Java Project

> Create Java Package

> Create Java Class

Write java code in the Class file and Run
