can teach you more languages in this course but I 'd
rather talk about Java now so I 'd like to thank you for
your time " Java is so famous because Java has
multiple features which helps it to be used in the
Enterprise Market"and then I hit the return key and
then I type in "print("Hello, World!" and then I hit the
return key and then I type in "print("Hello, World!"
now So here you can see it says "next in fact for you
as well you have to just click on next next everything
is smooth and depend upon your machine speed it
will change the speed might change okay that 's jdk
install but how do you verify if you have Java
installed?" "In case if you get error that the Java C
command not found even if you have installed it that
means the path is not set, how do you verify the path
here?"} This is our first line of code in our main()
method and it will print "Hello, world!"
also can do that too but in Python it is very simple to
do it like this print("Hello, world!")so basically you
can write your code in one line you can get the output
example so even before we jump to hello world let
me show you something so
, I 'll try to paste it in the console and it says the text is
not available in the console so the statement you have
to always mention is system.out.print and whatever
value you want to pass say enter and it should work
okay so this is a very simple statement that you have
to remember when you want to print something on
the console okay so just remember that and you can
just type or you can click on the up arrow to get the
option to reprint the text or you can just type six but
if you want to work with a text you have to put that in
double quotes and it should work okay
you have to do it okay so let 's do that so let 's put our
class here open bracket close bracket
is 3 so println will print 3 println will go on new line
and we can do the same thing here with other
variables so remember to use the println keyword
okay so remember to use the println keyword okay so
that's all for now remember to use the println
keyword okay What you can do is instead of using
print you can actually use something called print Ln
now print Ln means print new line so it will print and
it will go on new lines so we can do that here as well
so just say Ln Ln at the End Print Ln which is print
new line and now compile run and you can see we
got the value we got 5 and 15.
is just like this So when you want to get a variable
that has a value let's say five or six or maximum 127
you can go for byte now.we do something different
for character so for example in Java we have the
range which is from 0 to 9 and for character we have
the range which is from 0 to 127 so so in other words
you can use any character you want in Java and it
will be considered as a double value okay so now
