Java Scope - Scope of Variables in Java Tutorial #53

Welcome to this Java scope tutorial! To find the scope of variables in java, you look at the curly braces the variable is directly in. If it's in the same curly braces, after the variable is created, it's in the scope!

The scope of a variable in java is whatever is inside it's curly braces. For example:

if(true) {
int a = 0;
}

The scope of a is everywhere in the curly braces. Outside of the curly braces, a doesn't exist.

Variable scope in java can be tricky at first... But SURELY you'll get it :) If you followed along, congrats! You learned by-doing!

I hope you enjoyed this java scope tutorial! I like to have a nice mix of java tutorials and actual projects for you all :)

Was this able to help you learn the scope of variables in java?

I have a test in 2 hours and didn’t get this at all until now. Even though I am in a c++ class, the way you explained the scope of a variable and what it can read etc. made sense!! You are a life saver.

Constructors in Java have been giving me a hard time. Hoping a tut on this soon. P.s. you should consider creating a Udemy course.

Great tutorial but is it possible to access a varibale in the anonymous class without declaring it final? This have been my problem when I am programming an android studio. Because sometimes I need a variable that is being modifiled inside the anonymous class and to be used outside the anonymous class.

Cheers

Hello Alex, I am a fan of your vides. Whenever I make a new Java Project, I am always asked to create a new module when I click finish. Can you explain or make a video explaining what this module is in java?

[kapeh]

can I request a video about, encapsulation, and constructor. thanks a lot.

Look, he thought, he could make, a profit - off of us -- from KUIMAKA!

[dylancoxsa]

Please make a video on abstract classes. TY

[chrissabre]

Great job, some try to teach and simply do too much, like in Tims course 55 lines to teach !

[Monster]

So the } ⬅
Ends a statement or variable?

[TehBrian]

I love your videos but maybe start using IntelliJ? I feel like it’s better for teaching since most people use that and it’ll be easier for following along
