Java Programming for Beginners

By: SkillSprints Inc., Mark Lassoff

Overview of this book

Java is an object-oriented programming language, and is one of the most widely accepted languages because of its design and programming features, particularly in its promise that you can write a program once and run it anywhere. Java Programming for Beginners is an excellent introduction to the world of Java programming, taking you through the basics of Java syntax and the complexities of object-oriented programming. You'll gain a full understanding of Java SE programming and will be able to write Java programs with graphical user interfaces that run on PC, Mac, or Linux machines. This book is full of informative and entertaining content, challenging exercises, and dozens of code examples you can run and learn from. By reading this book, you’ll move from understanding the data types in Java, through loops and conditionals, and on to functions, classes, and file handling. The book finishes with a look at GUI development and training on how to work with XML. The book takes an efficient route through the Java landscape, covering all of the core topics that a Java developer needs. Whether you’re an absolute beginner to programming, or a seasoned programmer approaching an object-oriented language for the first time, Java Programming for Beginners delivers the focused training you need to become a Java developer.

The Math class library

A good portion of our time on any software development project is going to be spent teaching our program to solve the types of problems it would comes across on a regular basis. As programmers, we too will run into certain problems time and time again. Sometimes, we'll need to code our own solutions to these problems and hopefully save them for later use. However, more often than not, someone has run into these problems before, and if they've made their solution publicly available, one of our options is to leverage their solution for our own gain.

In this section, we'll use the Math class library, which is bundled with the JDK to solve some math problems for us. To start this section, create a brand new NetBeans project (I'm going to name it TheMathLib) and enter the main() function. We're going to write a very simple program. Let...
