"public" and "private" control access to members within a class. Marking a member or field "private" restricts access outside of that class. More info in the docs

I can understand how it can be confusing; I know i didn't understand the concept at first when i took a java course. To make it simple it controls whether or not you can access it. The reason why you wouldn't want it to be accessed is because you want to stay constant like the variable in the method. Basically by making it private the only time you can access that variable is within that method and not anywhere else within your line of code.
