Introduction to JVM Languages

Overview of this book

Anyone who knows software development knows about the Java Virtual Machine. The Java Virtual Machine is responsible for interpreting Java byte code and translating it into actions. In the beginning, Java was the only programming language used for the JVM. But increasing complexity of the language and the remarkable performance of the JVM created an opening for a new generation of programming languages. If you want to build a strong foundation with the Java Virtual Machine and get started with popular modern programming languages, then this book is for you. The book will begin with a general introduction of the JVM and its features, which are common to the JVM languages, helping you get abreast with its concepts. It will then dive into explaining languages such as Java, Scala, Clojure, Kotlin, and Groovy and will show how to work with each language, their features, use cases, and pros and cons. By writing example projects in those languages and focusing on each language’s strong points, it will help you find the programming language that is most appropriate for your particular needs. By the end of the book, you will have written multiple programs that run on the Java Virtual Machine and know about the differences between the various languages.

Summary


You learned a lot in this chapter. Let's look back at all the topics that we covered.

You downloaded and installed a JDK on your system. Then, you explored it thoroughly by examining its directory structure and looking at its most important commands. You studied how classes are organized in packages. This knowledge proved to be useful when you looked at the Java Class Library. You looked at some fundamental classes from the java.lang package and also studied the important ArrayList and HashMap classes from the java.util package. You wrote, compiled, and ran a simple program on a JVM instance and learned how to modify the ClassPath. Finally, in order to boost your productivity, you downloaded and installed Eclipse IDE.

Congratulations! Now that you have a good grasp of the JVM concepts, you are ready to dive into the world of JVM programming languages. Let's start with the language that started it all: Java.
