Basic To Advanced Selenium Java Full Course - Session 1 - Introduction to IntelliJ Idea & Java

What is an IDE?
IDE stands for Integrated Development Environment
Software for building applications that combine common developer tools into a single GUI
It consists of:
Source code editor to write code in different languages
Debugging tools to inspect code
Automated build processes for languages including code compilation
Syntax Highlighting
Autocomplete

What is Java?
Java is a Programming Language
Programming language is a set of instructions for computer to perform some specific tasks.
We can create different types of applications with Java:
WEB APPLICATIONS
DESKTOP APPLICATIONS
WEB SERVERS
EMBEDDED SYSTEMS
MOBILE APPLICATIONS

Java is a platform independent language
Java is a strongly typed language and case sensitive
We can run Java programs on all operating systems:
Windows
Mac OS
Linux

Java Components:
We need JDK to start development in Java
JDK stands for Java Development Kit
JDK allows us to create Java Programs
JDK also contains JRE (Java Runtime Environment)
JRE enables us to run our Java programs
JVM (Java Virtual Machine) is a subset of JRE. It is a run-time engine which runs the java applications. It calls the main method present in a java program.

Data Types In Java:
Data is information which is stored and processed by a computer

Pieces of data can be represented in code using data types

Java classifies different pieces of data with data type based on their value.

Primitive Data Types:
boolean – true or false value ( for example, light is on or off)
int – whole number ( for example, your age)
double – decimal number (for example, percentage of marks)
char – single letter (for example, initials or gender)

Reference Data Types (Non-Primitive):
class, interface, String, Arrays

Variables in Java:
Variables are used to store data values

Types of variables:
Local variables – Can be used in the same method where it is declared
Static variables – Can be used without creating an object of the class where it is declared
Instance variables – Can be used by creating an object of the class where it is declared
