Introduction to Object/Java Programming Training

Hands-on course
Duration : 3 days

  • Program
  • Participants / Prerequisite
  • Intra/Tailored

In this workshop, the fundamental principles of Object-Oriented Programming are taught through practice. It brings the participants a clear understanding enabling them, according to their needs, to control the technical relationships with their subcontractors, to fully supervise their development teams, or even to better control the construction of object oriented business requirements. It is also often used as a redeployment springboard towards Object-Oriented Programming.

Hands-on work

Each day is split in three theoretical sessions, each followed by simple exercises in which the principles, the use and the development of objects are illustrated. The participants will be able to get used to Eclipse, leader of Java objet development environments. Those exercises will be performed through Windows XP workstations, the JDK 1.5 and Eclipse 3.2.

General Presentation

  • Introduction.
  • Fundamental principles of Object-Oriented Programming: Abstraction/Encapsulation.
  • Fundamental principles of Object-Oriented Programming: Inheritance.
  • General presentation: the Language.
  • The Tools and the Library.
  • Releases of Java.
