Transcripts

welcome back aliens my name is z ready

and let's continue the series on Spring

framework now till this point we have

talked about what is spring and then we

have seen the project which we are going

to build but when you want to learn a

spring framework there are certain

things which you should know and you

should have in your machine the first

thing you need to know in Spring is Java

so the prerequisite is the Java language

of course right when you're learning a

framework you need to also know the

language on which you're going to build

so you need to know Java from start to

and so when I say end there's actually

no end but at least you should know uh

till threads and exception handling and

collection so basically I'm talking

about the syntax of java Loops

conditional statements how do you work

with array working with exceptions

threads and collection maybe threads is

not that important but you should know

it uh collection is very important and

one of the most important thing is the

oops concept so oops and interfaces

abstraction uh those things are very

important next uh when you talk about

framework we also need a build tool so

when you work on a project there are

certain build tools which you have to

use in fact any one either it can be

Maven or griddle so in this particular

series we're going to use mavin but if

you know griddle before it will be

easier for you to understand Maven uh

and if you don't know any of this Maven

is preferred for this series next uh you

need to also know about database

connectivity because anyway we are going

to connect our spring application with

database so if you know jdbc it will be

easier for me to explain you the

connectivity there then you have to

understand hibernate see we are going to

use spring data jpa here and then I'm

not going to explain how things are

working behind the SC because that's a

part of hibernate concept so you need to

know hibernate so that you can

understand spring data jpa properly and

also uh if you can work with XML files

uh that will be better so get used to

XML Json because of course this course

is not about Json and XML we will be

doing some configuration in XML and the

passing of data between the client and a

server will be done with the help of of

Json format so you should know what is

Json now question arise from where

you're going to learn this so don't

worry you are basically covered so in

the description you will find the videos

for this basically you will find the

video for a complete Java course where

you get Java Maven hibernate in one

video it also has spring but it has

spring five we are going we are going to

learn spring six here so till spring you

can learn everything and uh for Json

also there will be video XML also there

will be video so make sure that you

complete those so those are the

prerequisites before you start with the

course also you need to have certain

things in your machine example you need

jdk of course right Java development kit

because you're working on Java uh then

you also need a editor of course you can

use notepad here but then maximum time

you will spend in debuging and stuff so

prefer if you you can use a ID which

stands for integrated development

environment now there are multiple

options here and you can use whatever

you want to use example uh we can use vs

code we can use Eclipse we can use

intell idea and there are multiple tools

but I can work on this three properly so

I'm naming this uh vs code is good but

it's not optimized for Java they are

still working on it it's not there yet

uh so if you are happy with vscode

please continue with it because let see

ultimately we are using a maven for a

build tool and for the project structure

it doesn't matter which ID you going to

use the project structure will remain

same uh you can also use Eclipse which

is open source and free uh and it's of

the best tool available for Java

development so Eclipse you can use

Enterprise version and then comes

intelligy idea now the thing is

intelligy idea is great but they have

two versions one is a community version

and second is the ultimate version the

community version is free the ultimate

version is paid now if you are sure that

you're going to work on Java on

different projects and if you join a

company you're going to use intellig

idea I would suggest you to explore the

ultimate version it's awesome especially

for students they give you discount of

free you can check it out but it's great

Community version is also good and we

are going to use Community version here

and you'll be saying hey you know in

community version we don't have all the

features you know what we don't need all

the feature when you're learning things

and also if you're building a small

project and if you have a small team

Community version works but of course if

you want some Advanced features if you

want to boost your productivity explore

the ultimate version at least give it a

try for trial version so yeah that's

about the tools the things which are

needed in your machine and you're good

to go for jdk uh the version is go for

about 17 because if you want to work

with spring 5 jdk 8 works for spring 6

minimum you need jdk 17 I have jdk 21

here in this machine so I'm going to use

that uh again if you want to use it you

can also use 22 version but LTS versions

are better so stick to 21 and that

perfectly works so yeah that's a

prerequisite and the tools required for

this particular course see you in the

next video
