I didn't know I could have used the "==" equality operator, I thought I had to use a pre-defined method in the Character class. You have to use ".equals()" for Strings and Strings are nothing but character arrays acording to the Java books I've been reading/read.

Strings are objects (they even extend Object). While the underlying data structure is most likely a character array, Strings (obviously) have properties and methods. The purpose of a String is to hold a sequence of characters in a data type and perform whatever operations on that sequence. Because Strings are objects, using == compares the memory address of the object, rather than the value it holds. Because this hold for any object, the Object class defines a .equals() method for comparing the values of two objects. Primitive (non-object) types are simply data, without methods (global operators excluded). With primitives, using == compares the data in memory, not the address where the data is stored. Variables of type char are primitive. Hence, when you use:
the == works because charAt returns a character, and comparing it to 's' (a char constant) will compare the values.

[edit:] If you've ever used C++, this would be like comparing std::string to char*...

The beauty of Object Orientated Programming. So simple yet so complex!
