When I have started preparing for the Java Certification(Oracle Certified Associate Java SE 7 Programmer 1Z0-803), I couldn’t find the topics that should be prepared for the exam. After the referring to the many friends and books, I got the list of topics that we should get prepared.

It would be easy if we prepare the objectives for each topic. Following are the topics and their respective objectives that I will be preparing.
