J2ME

Bantry Technologies proposes a 3-day technical training on J2ME technology.

This fast-paced, programming intensive course provides complete coverage of the Mobile Information Device Profile (MIDP). Through comprehensive examples and hands-on projects, participants learn all facets of writing MIDP applications (MIDlets). Topics include development tools, event handling, both high-level and low-le vel user interface components, timers/tasks, persistent storage and networking

The training consists of an interactive class using slide presentations for theoretical sessions and exercises for practical work sessions.

A solid understanding of the Java programming language is required. Experience writing, debugging and deploying software, in any language, is highly recommended.

In order to fully benefit from this training, the attendees must have a good understanding of both the Java™ programming language. For each part described below, a practical session will be proposed to the student.
