Java ME: Develop Applications for Mobile Phones

The Java Platform, Micro Edition (Java ME) provides a rich and robust environment for the development of applications that run on mobile devices. Java is currently running on over 3 billion phones and offers unrivaled potential for mobile developers worldwide. Oracle is the leader in providing mobile phone technology. This course includes coverage of the development of mobile applications that use Connected Device Limited Configuration (CDLC)and the Mobile Interface Device Profile (MIDP), and the Lightweight User Interface Toolkit (LWUIT). Using the latest NetBeans IDE and JavaME SDK, students will develop user interfaces with MIDP, a game with sounds using Sprites and Layers, sophisticated user interfaces using LWUIT, applications that access a mobile database, and applications that leverage Location and Payment APIs.

Learn To:

• Create a simple payment application with the Payment API
• Create a simple location application with the Location API
• Create a simple game using the Game API
• Create applications using the Connected Limited Device Configuration (CLDC) and the Mobile Information Device Profile (MIDP)
• Create robust user interfaces with the Lightweight User Interface Toolkit (LWUIT)
