In this lecture we are discussing about setup and tools required:

1)Editor/IDE
2)Compiler or interpreter
3)Setup of jdk

#1
editor -It is a software which is used to write code
example- notepad, notepad++, sublime, visual studio code..

IDE – It is a software which is used to write code and compile and run the code .
example -eclipse ide, IntelliJ ide , visual studio
Note: With adding some extension vs code also work as IDE.

— Visual studio and vs code both are different
— in this course we are follow vs code

Visual Studio Code (VS Code) is a lightweight, open-source code editor developed by Microsoft.
It is a cross-platform application that runs on Windows, Linux, and macOS. VS Code is built on the same underlying technology as Visual Studio,
but it is designed to be a more streamlined, lightweight development environment.

link for vs code:https://code.visualstudio.com/Download
step to install:
i)select in which os you using windows, linux or macOS as per system download.
ii)just install and go next — next –next.
iii)Now it is ready to use

#2
Compiler and interpreter
–You should download compiler and interpreter to compile or run the code.
–for that we have toolkit jdk java development kit

two option to download jdk :
a) with oracle
b)open source like amazon cornetto

setup and installation for oracle jdk:
link to download:https://www.oracle.com/java/technologies/downloads/

— Select long term support version that is jdk 17 as per your operating system
–after download just instal by clicking next — next –next
–Set path in environment variable

for that :
step 1:find– c drive — program files — java — jdk — bin
and copy this path e.g c:\program files\java\jdk-17\bin

step 2:open environment variable — system variable or user variable –path — edit — new — paste the path of bin folder of jdk
Note: what is the difference between user and system variable?
user variable is only for that user and system variable is for all user

step 3: save

open cmd or PowerShell :
write java –version and javac –version
to check perfectly your compiler and jvm path setup
