Course Description
Overview
This course is designed to provide students with the knowledge and skills to become productive using object-oriented programming techniques in Java. Students are introduced to the fundamental concepts of object-oriented programming and how they are successfully applied in Java through classroom-based instruction and practical exercises.A student will quickly master the Java programming language and the packages that constitute its rich set of core libraries such as the Collections Framework.
This course can be hosted on a variety of IDEs such as RAD, Eclipse, MyEclipse Blue, Mars and SpringSource Tool Suite (STS). Please let your sales representative know the IDE you are currently using.
This course is one step in the following Learning Journeys:
