  • 00:00:00
    welcome back aliens my name is David
  • 00:00:02
    ready and in this video we're going to
  • 00:00:03
    talk about core Java in this particular
  • 00:00:06
    course which is a lengthy video you're
  • 00:00:08
    going to learn everything from the
  • 00:00:10
    basics of core Java to the end of core
  • 00:00:12
    Java now this is not the first time I'm
  • 00:00:14
    uploading the video on Java if you can
  • 00:00:16
    see from last few years you will find
  • 00:00:18
    multiple Java playlist and multiple Java
  • 00:00:21
    full-fledged video but we all know right
  • 00:00:23
    the quality of videos are going up every
  • 00:00:25
    day plus the number of features getting
  • 00:00:28
    added to a language is going up and
  • 00:00:30
    that's the reason I'm going to re-record
  • 00:00:32
    the entire course now this is a
  • 00:00:35
    full-fledged course and that's why it's
  • 00:00:36
    so lengthy but you cannot finish the
  • 00:00:38
    entire course in one day even if it says
  • 00:00:40
    12 hours or 13 hours it will take time
  • 00:00:43
    now let's talk about Java now why Java
  • 00:00:46
    is so famous now if you see the
  • 00:00:48
    programming index the top five
  • 00:00:50
    programming language you will always
  • 00:00:51
    find Java there maybe at the first
  • 00:00:54
    position or at the fourth position you
  • 00:00:56
    will find Java why Java is so famous is
  • 00:00:59
    because Java has multiple features which
  • 00:01:01
    helps it to be used in the Enterprise
  • 00:01:03
    Market I mean not just Enterprise Market
  • 00:01:06
    it can be used for mobile development
  • 00:01:07
    web development and of course Enterprise
  • 00:01:09
    application and most of the big
  • 00:01:11
    companies if you go there they are using
  • 00:01:13
    Java as their preferred language now in
  • 00:01:16
    Java we have a technology called jvm and
  • 00:01:19
    it's not just Java we have multiple
  • 00:01:21
    languages running on jvm so even if you
  • 00:01:24
    are working on some other language let's
  • 00:01:26
    say kotlin Scala groovy ultimately
  • 00:01:28
    you're working on Java technology and
  • 00:01:30
    that's why if you learn core Java it is
  • 00:01:32
    much easier for you to jump to different
  • 00:01:34
    languages and I've also observed
  • 00:01:37
    irrespective of which entry you are
  • 00:01:39
    going for it can be for development or
  • 00:01:41
    testing and that doesn't matter which
  • 00:01:43
    language your working on that maybe
  • 00:01:45
    python C sharp C plus plus they might
  • 00:01:47
    ask you Java questions because because
  • 00:01:49
    most of the interview questions are
  • 00:01:52
    based on Java because they feel that if
  • 00:01:54
    you know Java that means you know other
  • 00:01:56
    languages as well or you can learn other
  • 00:01:59
    languages easily as for my experience or
  • 00:02:01
    did I forgot to introduce myself uh my
  • 00:02:04
    name is Naveen Reddy I'm a corporate
  • 00:02:05
    trainer software developer and currently
  • 00:02:08
    focusing one on blockchain but Java is
  • 00:02:10
    my first love so I'm working on Java
  • 00:02:12
    from the last 12 years I've made
  • 00:02:14
    multiple courses on Java on YouTube and
  • 00:02:16
    different platforms and yeah I can teach
  • 00:02:19
    Java any day anytime
  • 00:02:21
    yeah sometimes I have to watch my own
  • 00:02:23
    videos to realize the concept but the
  • 00:02:24
    thing is I love Java and with this
  • 00:02:26
    experience I'm making the entire course
  • 00:02:28
    I was talking about my experience right
  • 00:02:30
    in fact I have learned multiple
  • 00:02:31
    languages in this all 12 years maybe I
  • 00:02:34
    have worked on 12 different languages
  • 00:02:35
    you can name it maybe C plus plus C
  • 00:02:38
    python Java JavaScript uh go language so
  • 00:02:42
    I love most of the languages some
  • 00:02:45
    languages are learned just for the
  • 00:02:46
    projects but then when I was learning
  • 00:02:48
    those languages I was I was feeling hey
  • 00:02:50
    it's it's so easy it's because
  • 00:02:53
    I have learned Java yes people say Java
  • 00:02:55
    is difficult just to start with it is
  • 00:02:57
    difficult maybe if you want to learn
  • 00:02:59
    Java as your first language it's kind of
  • 00:03:02
    difficult because if you're coming from
  • 00:03:04
    other languages let's say python or
  • 00:03:06
    JavaScript and if you want to print one
  • 00:03:08
    statement you can actually see that in
  • 00:03:10
    one line uh that's not the case with
  • 00:03:12
    Java right you have to write five lines
  • 00:03:13
    of code but yes once you make a big
  • 00:03:15
    application the number of lines will
  • 00:03:17
    remain almost same okay so Java is
  • 00:03:20
    difficult yes just to start with but the
  • 00:03:23
    thing is Java is one of the most
  • 00:03:25
    readable language what I mean by that is
  • 00:03:27
    if you are looking at someone else code
  • 00:03:29
    you can read the Java code line by line
  • 00:03:33
    uh that's not true with other languages
  • 00:03:35
    okay so Java is great in that terms Java
  • 00:03:38
    is maintainable and that maybe that's
  • 00:03:40
    why they most of the industries are
  • 00:03:41
    preferring to use Java now Java has
  • 00:03:44
    multiple features we'll talk about those
  • 00:03:45
    features later but just to name them we
  • 00:03:47
    got Voda which is right once one
  • 00:03:49
    anywhere which supports multiple
  • 00:03:51
    multi-threads it has a collection API
  • 00:03:53
    concept you can handle the exceptions
  • 00:03:55
    and we are going to learn everything in
  • 00:03:58
    this particular course now just to go
  • 00:04:00
    for the history of java Java was made in
  • 00:04:02
    1995 by sun microsystem and it was led
  • 00:04:05
    by the team of James Gosling later on
  • 00:04:08
    Oracle bought Sun so now the trademark
  • 00:04:10
    of java belongs to Reichel yes in
  • 00:04:14
    between Oracle did some messed up things
  • 00:04:16
    with Java but yeah they are back on
  • 00:04:18
    track and the beauty is Java is getting
  • 00:04:21
    updated every six months not the major
  • 00:04:24
    updates but they are working hard to
  • 00:04:27
    make Java as the most powerful language
  • 00:04:29
    so I hope you were excited for the
  • 00:04:31
    entire course we are going to start from
  • 00:04:33
    the basic as I mentioned and you will
  • 00:04:35
    learn a lot of Defense stuff but as I
  • 00:04:37
    mentioned it's not about completing the
  • 00:04:39
    entire course in one day you can use a
  • 00:04:42
    timeline to jump between these sections
  • 00:04:44
    and also with this we also have a code
  • 00:04:46
    there so in the description you will
  • 00:04:48
    find the link GitHub link where you can
  • 00:04:50
    access all the codes and maybe it will
  • 00:04:53
    help it will be helpful for you to write
  • 00:04:54
    this code so let's start the journey
