Java Training Overview
Fast Track to Java 8 and OO Development is a fast paced course suitable for programmers with existing programming experience. It can be taught to audiences with less experience by reducing coverage of the optional, more advanced topics.
Java is one of the most important programming languages used today, and its correct usage is a critical part of many systems being written now. The basics of the language are relatively easy, but the challenge lies in learning how to use it well. This is especially true regarding the Object-Oriented nature of Java, which for many developers is a new way of approaching system design and construction.
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 covers all the key OO capabilities and how to use them in Java, including 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 overviews of accessing databases with JDBC and JPA (including labs using JPA).
This course is suitable for environments using Java 7 or Java 8. The material and labs include coverage of useful new Java 7/8 capabilities such as strings in switch statements, try-with-resources, and lambda expressions. 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 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.
