To understand concepts of J2ME programming, you can read official J2ME tutorial, which is very comprehensive. Some useful books are also listed in resources section.

Most of questions will be code-based and hence, it is very important that you understand how code is structured for various specifications.

You might want to consider purchasing SCMAD exam simulator by Whizlabs, which contains numerous questions of varying difficulty levels spread across five mock exams and a quiz and also lots of useful tips for exam.

Tips and pitfalls

·Understand conceptual difference between a J2ME configuration (like CLDC) and a J2ME profile (like MIDP). ·Memorize software and hardware requirements of various specifications. ·Memorize class hierarchies of important APIs like Generic Connection Framework, High level and low level UI API, Media classes of MIDP 2.0 and MMAPI 1.1. ·The exam tests understanding of features and differences between low level and high-level API for UI programming. So, learn them well. ·Understand that differences between media support of MIDP 2.0 and MMAPI 1.1. ·Apart from knowledge of writing proper J2ME code, exam also tests ability to write valid Java Application Descriptor (JAD) and manifest files that are used to markup deployment details of an application. So, practice writing descriptors well and deploy application in toolkit to understand behavior of various deployment tags. ·Remember that exam is a vendor neutral exam. So, you can safely ignore learning vendor APIs (like APIs provided by Nokia, Sony Ericsson, and so on). ·The best reading material for this exam is specification document. So, allot enough time to go through these documents and learn concepts and API well. ·Make sure what you read is relevant to exam objectives. A common pitfall is reading and spending time on things that you may not require for exam. ·As mentioned earlier, try to develop a practical example for each concept as this will help in a better understanding of concepts.
