I am just beginning to program in Java and I noticed that String is the only type that starts with a capital letter.
Is there a reason behind this?

By convention, Java types that start with an upper case are Objects, while those that start with a lower case are primitives.
A primitive cannot have a method attached to it, because there is no Object to hold the method. Also primitives cannot be subclassed, for the same reason.
Primitives also promote, which is something that Objects cannot do, as promotion changes the effective type of a primitive in ways that are not object oriented compatible.
