Transcripts
hey everyone I hope you all are safe and
doing good so this is one of the most
frequently Asked question ma'am we want
to learn DSA which language we should
choose C++ or Java or python because
python is also nowadays in trending
language see first of all the question
is not a valid question actually what is
DSA DSA is all about problem
solving right in the tech interviews of
those top tech companies they want to
check your problem solving skills have
you approach a problem have you break
down that problem have you optimize your
solution right that is why you know the
most of the questions rolve around
DSC right in those top tech companies if
you want to go like Google Microsoft
Amazon meta and these right now it's not
just about coding or it's not just about
you know doing writing programming just
one language C++ for Java it's about
problem solving
skills they just want to check your
problem solving skill you write down
code in C++ Java or python if your code
is good it's optimized you are able to
think you are able to approach that
problem properly in optimized manner you
are good
to right even you can learn the DSA
Concept in pseudo code you don't need to
write a proper code in any language if
you want to understand the concept and
all but yeah if you want to yeah
definitely you are going to Implement
those concept then you need a language
definitely C C++ Java or python right
and the most commonly used languages are
like C++ Java and python so you are
confused most of the students confused
about which language to choose C++ Java
or python right so one thing Let Me
Clear one thing first it doesn't matter
mainly if I compare C++ in Java then
both the languages are great programming
language for Lear learning and
implementing DSA concept it doesn't
matter a lot right you can go either for
C++ or Java doesn't matter but still if
you want to choose one language then you
need to consider some
factors right like if you want to choose
between two
bikes
right yeah almost similar bikes are
there all bikes are good but if you want
to choose then there are many factors
based on that you compare those Vehicles
those bikes or cars and all and and you
according to your preferences your goals
according to your condition your
financial condition you choose that
product or that one by or that car and
all right so same with this there are
many factors while choosing C++ and Java
first thing see if you are comfortable
or if you are familiar with any one
language like you have done C and C++ in
just in your 11th and 12th so you just
continue with C++ don't just skip I mean
don't just jump to a new language just
to go for DSA concept continue with that
language learn DSA and all see if you
are very good in one language you have
proper knowledge of one language it's
it's you know it's very easy for you to
switch to another language don't worry
it's okay and when you're going to
Industry maybe you have given sometimes
this happens maybe you have given your
interview in C++ you got selected and in
after you go to that company you will be
working on a project which is in Java
then you need to learn Java there right
so it doesn't you know matter actually
right because after going to that
industry over the time period you need
to learn other languages as well it's
not like that you just learn one
language and that's it right you are set
no right if you are familiar with C++ or
comfortable with C++ just learn DSA with
C++ if you are comfortable with Java go
for Java if you are comfortable and you
know both C++ and Java very well then I
I would recommend go for Java why Java
I'll tell you see later but before that
just want to remind you if you want to
learn DSA with Java then I am going to
start a course mastering data structure
and algorithm with the Java from 19th of
September so the early bird offer is
still going go extra 10% discount for
first 500 student in this course I will
be covering complete Java language first
then complete DSC it's for extreme
beginner to advanc level so if you have
no prior coding experience you don't
know any language it's okay I'll teach
you everything we first I'll teach you
first Java and then we'll go for DSC
right with some projects case studies
assignments quizzes and much more and
doubt resolution support as well during
the course right so classes will be
started from 19th of September the link
you will get in the descrip description
box as well as in the pinned comment you
just go and check out that course one
factor is this right second factor is
the purpose why you want to go for DSA
concept see if you want to learn DSA
Concept in the context of CP you want to
go in competitive programming definitely
you go for C++ why so because it is
faster and there in CP when you're are
solving problems when you're going for
those contest online contest the speed
matters execution time because they have
mentioned like they generally mention
one or 2 second
and sometimes if you write the same code
in other language python or Java then
the error comes like time limit exed it
even though you have written the same
logic but still because Java is sorry
C++ is the fastest one python is the
slowest Java is in between these
two right it's not like that you cannot
do CP in python or Java many do many
prefer python or Java for CP but
preferred language for for CP is C++
because of its faster execution right
it's but and the you know that that um
concept or
that syntax is also short like if you
want to print something just write C out
in Java you have to write system do out.
print Ln and there you write whatever
you want to print and here we simply
write C out that's it so sometimes
because of this shorter snx also they
prefer C++
right now see now if you want to go in
that industry like if you want to
develop operating systems compilers
system software drivers they need
lowlevel memory management right then go
for C++ there C++ is used still used
right and in some you know hfts also
like the hft means high frequency
frequency trading they are the firms
right now you know nowadays they offer
on almost one CR or two CR four CR
package to IIT
hfts it's way more than the the the
offer you know of product based
companies right because in hfts
developer you know write down complex
algorithm but there the speed the
execution time latency that matters a
lot and because C++ is faster that is
why f is used C++ language to write
algorithms that is why they prefer the
one who is good in C++
right so in nft is basically you know
using that algorithm they analyze the
market data right they buy and you know
sell the stock and all and they do you
know a large number of transactions in
seconds and within that second they can
earn cores and even they can lose cores
so that is why there the speed matter
the speed of the algorithm because
everything the analysis of the data
selling and buying and all this thing is
done automatically and they write
algorithm for that right so that is why
the speed of algorithm the execution
time the latency matter here a loot that
is why C++ is used right so basically if
you want to go in CP system programming
and hfts or those you know high if you
want to do in those Industries where the
the the high performance you know
intensive tasks are required then go for
C++ otherwise if you want to learn or
you want to go in in a professional way
in that industry
you want a job and that's it if your
goal is not specific to these things
right what C++ required then go for Java
because it is widely used in the
industry even in those Enterprise
level right even you know those servers
in servers and web servers cloud and
infrastructures and many big tech
companies Google meta Amazon they use
Java for their codebase they have a
large code base for their servers their
server runs on Java right so Java is
widely used in the industry third Factor
comes resources so both C++ and Java
there are many resources if you want to
go for DSA with C++ or DSA with Java
there would be many paid resources there
would be many free resources also so in
this case both are same right fourth
thing level of difficulty for a beginner
purpose yeah C++ is a little bit hard to
learn because of there's many concept
like pointers memory management you have
to do memory management yourself you
will manage you will allocate memory you
will free memory right so basically we
are the you know we are allocating the
memory and deallocating memory and all
so memory leaks are there in Java there
is automatic garbage collector you don't
need to you know worry about the memory
management at all there is no pointers
so it is little bit easy to
learn language right but I know many
students ask this question C++ versus
Java in the context of job which
language is going to pay you higher
which language is having more jobs right
so definitely more jobs Java language
that is for sure but high paying we
cannot say simply C++ or Java because I
have given you an example as if these
are using C++ and they are paying even
cores right and even there are so many
Java developers who are you know uh
earning more than C++ developers there
are many C++ developers who are earning
more than Java developers so in case of
like which language is going to pay you
more we can't say
directly right but yeah in terms of jobs
available in the market in the terms of
job demand Java is one of the most
preferred language there are so many job
openings in Java and for placement point
of view you can choose either language
C++ or Java because they see see if you
are aiming those top tech companies they
will see your problem solving skill they
will ask
DSA it doesn't matter you are going to
solve that problem in C++ Java or python
basically many students prefer C++
because of the speed I have told you and
as well as the shorter
syntax right because at that point of
time when you are solving the problem
you know problem that matters a lot the
time limit and all that matters a lot so
rather than writing these this line I'll
prefer to write only C out so they
prefer C++ that's why right but it
doesn't make a difference much and if
you are applying for specific roles like
Java backend developer so obviously you
learn Java C++ developer obviously you
will learn
C++ right so there's no question C++
versus Java in that case if you are
applying for specific roles and Java why
Java is almost in you know widely used
in industry because we can do everything
in Java website development you can do
development you can do back end thing
also you can do Android app development
I mean you can develop apps also right
web servers so many things we can do in
Java that is why it is widely used in
Industries and there are many jobs in
Java rather than you know in C++ so the
summary is C++ is in demand in
specialized field like system
programming game development high
performance Computing competitive
programming right and Java is in high
demand across multiple Industries
especially in Enterprise software
development web development Android app
development so it is one of the top
language in terms of job demands so if
you want to go for DSA with Java right
you can enroll in a course in my course
that is mastering DSA with Java there
I'll teach complete Java first then we
go for DSC plus we'll be discussing some
projects case studies quiz assignment
and much more right so the early bird
offer is still going on which is extra
10% discount for first 500 students the
enrollment link you will get in the
description box of this video you go and
check out I hope this video clarified
your doubt C++ vers Java so now I'll see
in the next video bye take care
