Course overview

The Developing Mobile Phone Applications With J2ME Technology course provides students with hands-on experience with developing mobile applications on the Java 2 Platform, Micro Edition (J2ME platform) using Connected, Limited Device Configuration (CLDC) and the Mobile Interface Device Profile (MIDP). The course provides information about MIDP 1.0 and MIDP 2.0 specifications, concepts, and capabilities.

Goal

Upon completion of this course, students should be able to:

• Explain the J2ME platform architecture and the role of configurations and profiles
• Build basic MIDP applications (MIDlets) and incorporate enhanced multi-media into MIDP-based applications
• Create and implement event-driven user interfaces using the high-level and low-level application programming interface (API)
• Implement local data storage on devices using the Record Management System (RMS)
• Create applications that use network-based information
• Describe the MIDP 2.0 security enhancements

Target group

Students who can benefit from this course are Java technology developers, designers, and architects, who want to develop mobile applications for the MIDP. In addition, this course will benefit architects who design mobile technology solutions, and Java migration technologists, who need to leverage existing code to the new platform.
