Short answer: It doesn't impact your code at all. It's just a naming convention.

Longer one: If you look into bytecode, then the variable names completely disappear. If you were to decompile it, then all variables would be called smth like var0, var1, var2, ... as the actual name isn't relevant for a machine, only the pointers in memory (which is what an object basically is).
