Hi,
Core JAVA is the base of all JAVA technologies and you should be aware of all the OOPs concepts Encapsulation, Polymorphism, Abstraction and Inheritance.
Multithreading and exception handling are the most challenging topics when talk about programming for some device having very limited resources like processor, heap memory, storage, display and input (i.e. keypad in most cases). No floating-point calculations available if you are working with MIDLet 1.0
