First make sure you really like programming. Are you good in logics? Can you spend time on one boring subroutine trying to fix it? Do you easily get bored (can't be, u have to write documentations).

If your answer to first 2 questions are YES and last one is NO (last one is not a must) then you can be a programmer.

JAVA is OOP and is considered easier than C or C++ (Java is a non native C++), but JAVA has so many derivatives and additives (libs) that the scope gets bigger and more complex at times.

Having said that, first practice some general programming. Then get some good Java books. It will be few years before you make big bucks.
