Description

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 1 – Generic and Generic Programming
•why to use generics and generic programming
Section 2 – Basic Generics
•generic types

•fundamentals of generics and generic programming
Section 3 – Bounded Type Parameters
•bounded type parameters
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

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.

Software Engineer
Hi! 

My name is Balazs Holczer. I am from Budapest, Hungary. I am qualified as a physicist. At the moment I am working as a simulation engineer at a multinational company. I have been interested in algorithms and data structures and its implementations especially in Java since university. Later on I got acquainted with machine learning techniques, artificial intelligence, numerical methods and recipes such as solving differential equations, linear algebra, interpolation and extrapolation. These things may prove to be very very important in several fields: software engineering, research and development or investment banking. I have a special addiction to quantitative models such as the Black-Scholes model, or the Merton-model.
