课程简介:
This is a 5-day course that provides a broad and deep introduction to Java for non-Java programmers. The course covers all the basic concepts of Object-Oriented Programming and Java. Included is the material and labs on all the key OO concepts, including topics like encapsulation, composition, and inheritance. It also includes some coverage of advanced Java capabilities such as JDBC/JPA and the Collections Framework, as well as coverage and usage of many of the newer capabilities in Java 7. There are a large number of labs, and all labs except the first are done with a development environment (e.g. Eclipse or RAD). The lab instructions include detailed directions on the particular environment for that version of the course.

培训对象:
Programmers with exposure to Java or related languages (ie. C or C++) or programmers with entirely unrelated backgrounds.

预备知识:
Previous programming experience in C, C++, or C#®, and some knowledge of basic object-oriented concepts are recommended.
