Java Training Overview
Fast Track to Java and OO Development 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 Java 9+ module structure, and other recent features 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 11-17. 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.
