Introduction to Collections, Generics & Reflection in Java

Learn the basic concepts and functions  that you will need to build fully functional programs with the popular programming language, Java.
This course is about generics in the main. You will lern the basics of generic types, generic methods, type parameters and the theoretical background concerning these topics. This is a fundamental part of Java so it is definitly worth learning.

•reflection and frameworks (such as Spring)
Learning the fundamentals of Java is a good choice and puts a powerful and tool at your fingertips. Java is easy to learn as well as it has excellent documentation, and is the base for all object-oriented programming languages.
Jobs in Java development are plentiful, and being able to learn Java will give you a strong background to pick up other object-oriented languages such as C++, or C# more easily.
