Introduction to Scala
The name Scala derives from a combination of the words βscalableβ and βlanguageβ. Scala is a functional programming language, which runs on top of the Java virtual machine and can use any Java class. Scala is well suited for distributed programming and big data. It is what Apache Spark is built in and can provide better performance when compared to Python and is much less verbose than Java. Whether youβre learning about functional programming or starting a career in big data, Scala is a great place to start.

Hibernate Basics
Most meaningful applications you will write will have a database associated with it. Knowing how to connect with and incorporate this data is critical to success as a Java developer. In this course, we'll cover how to connect a Java application to a database using what's called JDBC, or Java Database Connectivity. Then, we'll use the convenient approach of including an ORM, or Object Relational Mapper. This will allow us to interact with our data using object-oriented techniques instead of exclusively relying on hard-coded SQL. The ORM we will use is called Hibernate, and is one of the most popular ORMs available.

Java Annotations
Annotations have rapidly become the preferred approach to integrating powerful third-party libraries into your own Java applications. In this course, we'll first explore the basic use of annotations to give the compiler instructions. Then, we'll use more advanced techniques to create our own annotation and look for it using reflection.
