Fast Track to Java 9-11 and OO Development – 5 Days

Course Description – Fast Track to Java 9-11 and OO Development Training

Fast Track to Java and OO Development training provides a comprehensive introduction to Java. It is suitable for programmers with good working programming experience (no Java experience needed). It can be taught to audiences with less experience by reducing coverage of the optional, more advanced, topics.

In addition to covering basic Java programming, the course provides a solid understanding of the core OO and Java concepts and practices needed to create well-designed Java programs. This includes creating well-designed Java classes, encapsulation, composition, and inheritance/interfaces.

The material and labs include coverage of useful new Java capabilities such as the new Java 9 module structure, type inference (Java 10-11), and API enhancements. It also introduces important APIs such as the Java Collections Framework, and JDBC/JPA. This course is suitable for environments using Java 9-11. It also covers details of the Java release cycle, and Long Term Support (LTS) releases.

Be prepared to work hard and learn a great deal! The course can be held on-site & customized to fit your needs.

All labs are done using the Eclipse Development Environment, and the lab instructions include detailed directions on using Eclipse and the Eclipse wizards and tools.

From Wikipedia – Simula was the first object-oriented programming (oo)language. Java, Python, C++, Visual Basic .NET and Ruby are the most popular OOP languages today. The Java programming language is designed especially for use in distributed applications on corporate networks and the Internet. Ruby is used in many Web applications.
