Capitalization of objects and variables

Why do some objects get capitalized and variables are always capitalized? (String is always capitalized when declaring variable types) When referring to objects, console is not capitalized by System is. Does it matter? Why or why not?

Samantha;

Welcome to Treehouse!

Great questions. Does it matter, yes. Java is very case sensitive and you will get errors if you try to declare Strings as string instead of String or Int instead of int. Why the difference? In short int is a primitive data type, String derives from Object and is a class.

It is all part of the Java Code Conventions.

That probably just raised more questions than it answered, but there you have it.

Happy coding,

Ken

Thanks. I'll just have to read the Code Conventions to get up to date on that. Glad there's a reason!
