Introduction to Programming

Overview of this book

Have you ever thought about making your computer do what you want it to do? Do you want to learn to program, but just don't know where to start? Instead of guiding you in the right direction, have other learning resources got you confused with over-explanations? Don't worry. Look no further. Introduction to Programming is here to help. Written by an industry expert who understands the challenges faced by those from a non-programming background, this book takes a gentle, hand-holding approach to introducing you to the world of programming. Beginning with an introduction to what programming is, you'll go on to learn about languages, their syntax, and development environments. With plenty of examples for you to code alongside reading, the book's practical approach will help you to grasp everything it has to offer. More importantly, you'll understand several aspects of application development. As a result, you'll have your very own application running by the end of the book. To help you comprehensively understand Java programming, there are exercises at the end of each chapter to keep things interesting and encourage you to add your own personal touch to the code and, ultimately, your application.

Exercise – JDK tools and utilities

On your computer, find the Java installation directory, and list all of the commands (tools and utilities)—the executables—present there.

You are in the right spot if you see java and javac among other executables.

Answer

Here is the list of all of the executables installed with Java 10.0.1:

One of the ways to find this directory is to look at the value of the environment variable PATH. For example, on a Mac computer, Java is installed in the directory /Library/Java/JavaVirtualMachines/jdk-10.jdk/Contents/Home/bin.

The Oracle documentation that describes the JVM installation location can be found at https://www.java.com/en/download/help/version_manual.xml.
