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.
