Fast Track to Java 17 & OO Development Training

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.
