Variables inside of loops scope?

Hi Dylan,

If you need a variable to be only available for a particular task then better not to declare it as global (same as outside of the loop/method). But the variable is only visible inside the scope of the mothod/loop.

So If the variable that controls a loop is not needed outside of the loop, it's best to declare the variable in the initialization expression (Java Docs) of that loop. Declaring variables inside a loop limits their life span and reduces errors.

Another point is that creating a local variable may reduce memory usage. When you exit a method or a loop, the local variables inside disappear. Only instance variables maintain their value over method/loop calls and use more memory recouces.

Does it make sense?
