Scala for the Impatient LiveLessons, best-selling author and professor Cay S. Horstmann builds upon your knowledge of Java and introduces Scala as a “better Java.” You will see how Scala blends object-oriented and functional programming and gives you the choice of when and how to use each paradigm.

Scala is a modern programming language for the Java Virtual Machine (JVM) and combines the best features of object-oriented and functional programming. Scala has quickly risen in popularity because it allows developers to write programs more concisely than in Java, as well as to leverage the full power of concurrency. Since Scala runs on the JVM, it can access any Java library and is interoperable with Java frameworks.

Scala for the Impatient LiveLessons begins by covering the basics you need to know when learning a new programming language: values and types, branches and loops, functions, and data structures for collecting elements. The course then turns to the object-oriented features of Scala in lessons 4 and 5. At this point, you are ready to put Scala to work as a better Java. But to go beyond that point, the final two lessons teach you how to take advantage of the functional part of Scala. When you have completed this course, you will know enough Scala to effectively use Scala frameworks such as Play or Apache Spark.

Throughout the course, lab exercises are included in the lessons for hands-on practice. Learning a programming language is not a spectator sport. You will only learn by doing. For each lab, Cay introduces the exercise and then it is your turn to practice. It’s recommended that you pause the video, bring up your development environment, and get to work! When you are done, compare your solution against the solution presented in the video.

After this course, you will be able to:

  • Understand core language features: values and types, control structures, and functions
  • Use arrays, maps, and tuples for collecting elements
  • Comprehend object-oriented programming in Scala: classes, objects, packages, inheritance, and traits
  • Understand functional programming in Scala and how to work with higher-order functions
  • Leverage Scala’s powerful pattern matching and case classes
  • Know enough Scala to use frameworks such as Apache Spark, Play, Akka, and Spray
