Java Programming Tutorial - 20 - Conditional Operators Video Lecture | Java Programming Fundamentals: For Beginners - Back-End Programming

sup guys is spunky welcome to your 20th
Jeff tutorial and this story I'm gonna
be talking to you guys about something
called a conditional operator
now what conditional operators are is
pretty much another way of using an
if-else statement but it's really
compact and it's really small
so go ahead and create a variable called
age and set it equal to 21 or set it
equal to what everyone it's not going to
matter what a conditional operator is is
let me just show you make a simple print
statement system out print line and in
this print line this um operator is so
small that we can write the entire thing
as an argument and what it is is this
the first thing you need to do is give a
test so if age is greater than 50 after
you give it a test you add a question
mark and what this means is treat this
as a boolean expression so it's gonna
see if age is greater than 50 is it well
now you have to give it two options if
this is true you're gonna give it it's
gonna execute the first option if it's
false it's gonna execute the second
option so since this is already in a
print statement all we have to do is add
strings of text so if it's greater than
50 put you are old and how you separate
the true from the false you add a colon
not a semicolon
that's a regular colon and if it's false
let's put you are young so let me go
ahead and run this and let me show you
guys what it does it says you are young
in the run box and let me show you guys
why this is don't mind any of this
that's not what we're learning today
what it does is we asked it a simple
question is age greater than 50 well you
only have two choices yes or no so then
after you do this after the question
mark you need to give it what happens if
this is true
if H is greater than 50 and this is true
we want you to do this if it's false
then and it's less than 50 then we want
you to do this
so again ask you a question this is
gonna come true or false if it's true do
this if it's false do this in that order
and don't forget this question mark and
also the colon right here and remember
it isn't a semicolon so that's your real
quick tutorial on how to use a
conditional operator and again this is
um sometimes can be substituted for
if-else statement but I'm usually gonna
be writing just basic if-else statements
I just wanted to show you guys in case
you come across this you actually know
what it is in aren't loss so that's it
