What you'll learn

Java 25 added a number of capabilities targeting ease of use, especially for those new to Java. Fast Track to Java and OO Development provides a comprehensive introduction to Java using these new capabilities. 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. It also covers details of the Java release cycle, and Long Term Support (LTS) releases.

The material and labs include some coverage of useful advanced and new Java capabilities such as the Java module structure, Java records, and other recent features and API enhancements. It also introduces important APIs such as the Java Collections Framework and the Date/Time API.

This course is suitable for environments using Java 25. It covers the many new features of Java 25 that make it easier for new users to learn it, as well as more advanced features that support creating cleaner and more compact code.

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