Java Training Overview
Fast Track to Java for OO Developers is a demanding, fast paced course suitable for programmers with existing experience in other OO languages such as C++ or C#. It builds on the knowledge that Object-Oriented programmers already possess to provide an accelerated approach to learning the Java programming language and good Java programming practice.
In addition to teaching you everything you need to become productive in basic Java programming, this course draws on our extensive experience to provide a solid understanding of the core OO and Java concepts and practices needed to create well designed Java programs. It leverages the student’s existing knowledge about OO programming to show how to use Java at an accelerated pace. This includes material on creating well designed Java classes, using encapsulation, building more complex functionality with composition, and using inheritance to share functionality and create specialized types. It also covers more advanced concepts such as using interfaces, working with the Java Collections Framework, and accessing databases with JDBC/JPA.
This course is suitable for environments using Java 8. The material includes coverage of all current Java capabilities that are within the scope of the material, including new Java 8 capabilities such as the new Date/Time API, and an overview of lambdas. It also stresses the use of good coding practices for all the examples and labs. This course is available for most IDEs, such as Eclipse, IntelliJ IDEA, and IBM RAD
Be prepared to work hard and learn a great deal! The course can be held on-site & customized to fit your needs.
