About 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.

Section 4 - Type Inference
what is type inference
Section 5 - Wildcards
what are wildcards?
lower bounded wildcards
upper bounded wildcards
wildcards and bounded type parameters
Section 6 - Type Erasure
what is type erasure?
bridge methods and type erasure
Section 7 - Collections Framework
the collections framework
measuring the running time of algorithms
what are data structures?
Section 8 - Lists
ArrayList and LinkedList
performance comparison of LinkedLists and ArrayLists

TreeMaps
Section 11 - Sets
what are sets?
HashSets, LinkedHashSets and TreeSets
Section 12 - Sorting Collections
sorting arrays and collections
Comparable and Comparator interfaces
sorting with lambda expressions
Section 13 - Stream API
streams

map() and flatMap()
reduce()
Section 13 - Reflection
what is reflection?
annotations and reflection
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.
