Currently used at many colleges, universities, and high schools, this hands-on introduction to computer science is ideal for people with little or no programming experience. The goal of this concise book is not just to teach you Java, but to help you think like a computer scientist. You’ll learn how to program—a useful skill by itself—but you’ll also discover how to use programming as a means to an end. Authors Allen Downey and Chris Mayfield start with the most basic concepts and gradually move into topics that are more complex, such as recursion and object-oriented programming. Each brief chapter covers the material for one week of a college course and includes exercises to help you practice what you’ve learned. Learn one concept at a time: tackle complex topics in a series of small steps with examples Understand how to formulate problems, think creatively about solutions, and write programs clearly and accurately Determine which development techniques work best for you, and practice the important skill of debugging Learn relationships among input and output, decisions and loops, classes and methods, strings and arrays Work on exercises involving word games, graphics, puzzles, and playing cards

Discover object oriented programming with Java in this unique tutorial. This book uses Java and Eclipse to write and generate output for examples in topics such as classes, interfaces, overloading, and overriding. Interactive Object Oriented Programming in Java uniquely presents its material in a dialogue with the reader to encourage thinking and experimentation. Later chapters cover further Java programming concepts, such as abstract classes, packages, and exception handling. At each stage you’ll be challenged by the author to help you absorb the information and become a proficient Java programmer. Additionally, each chapter contains simple assignments to encourage you and boost your confidence level. What You Will Learn Become proficient in object oriented programming Test your skills in the basics of Java Develop as a Java programmer Use the Eclipse IDE to write your code Who This Book Is For Software developers and software testers.

Java Programming for the Internet gives programmers who wish to write Java "applets" a step-by-step approach. Readers learn Java programming techniques, get the tools they need to build real-world interactivity into Net applications and acquire the latest methods for presenting multidimensional, interactive Web pages.

Java is the world’s most popular programming language, but it’s known for having a steep learning curve. Learn Java the Easy Way takes the chore out of learning Java with hands-on projects that will get you building real, functioning apps right away. You’ll start by familiarizing yourself with JShell, Java’s interactive command line shell that allows programmers to run single lines of code and get immediate feedback. Then, you’ll create a guessing game, a secret message encoder, and a multitouch bubble-drawing app for both desktop and mobile devices using Eclipse, an industry-standard IDE, and Android Studio, the development environment for making Android apps. As you build these apps, you’ll learn how to: -Perform calculations, manipulate text strings, and generate random colors -Use conditions, loops, and methods to make your programs responsive and concise -Create functions to reuse code and save time -Build graphical user interface (GUI) elements, including buttons, menus, pop-ups, and sliders -Take advantage of Eclipse and Android Studio features to debug your code and find, fix, and prevent common mistakes If you’ve been thinking about learning Java, Learn Java the Easy Way will bring you up to speed in no time.

Finally - an easy-to-learn approach to program Java applets! The book covers the Swing graphics (Java 6) using Java applets. It starts with an introduction to computing, then dives right into programming to give you a chance to create first. Simple drawing techniques are covered, followed by image processing, components, layout managers, design, conditionals, events, loops, debugging, collections, threads, game programming, Internet applications, security issues, reading/writing files on the server and email and how to host your applets on the Internet. This book is intended for beginners with a gentle approach to learning how to program allowing you to explore the concepts of programming through a hands-on first approach.

Sri Lanka is a tropical island that lies approximately halfway between Africa and Australia along the northern rim of the Indian Ocean, and has one of the best recorded prehistoric sequences in South Asia. A review of its prehistory is a vast subject. The present study investigates the island's hunter-gatherer archaeology between the Late Pleistocene and the middle Holocene, with lowland Wet Zone rockshelters as the principle topic of study. This work synthesises past and current archaeological research in the island as well as presenting new findings from excavations in the Batadomba-lena rockshelter and the open-air site of Bellan-bandi Palassa. The excavation of Batadomba-lena has provided fresh data for understanding human adaptations to the changing environment between approximately 36,000 and 12,000 years ago. A rainforest environment evidently persisted throughout this period in the environs of the site, but the climate was cooler at around the Last Glacial Maximum. Intensive occupation, succeeded by increased attention to the management of plant resources, followed the Last Glacial Maximum. Microliths, small tools defined by the presence of blunting retouch, as well as the bifacially trimmed Balangoda Point and polished bone points, were evident from the earliest occupation. The symbolic capacities of the inhabitants were also revealed through the recovery of ornaments and ochre fragments throughout the sequence. The Batadomba-lena sequence has important implications for the Out-of-Africa theory on modern human origins, as well as Sri Lanka's recognition of its cultural heritage.
