Do you really need to put a blank value when initializing a String variable or any other variable?

I tried typing just String bestSport; and there was an error saying that the bestSport variable has not been initialized.

The Code Challenge asked you to declare and initialize the variable bestSport, so that's why you're getting the error. In a normal Java compiler, just declaring a variable would not cause any errors (but you'll want to initialize it before you use it).

When it's checking to see if your answer is correct, it uses the variable bestSport, but since you didn't initialize it, you get that error:

JavaTester.java:26: variable bestSport might not have been initialized
if (bestSport instanceof String && bestSport == sports[0]) {
^
1 error

Thank you answering my question. It is clear to me now.
