"Java程序设计教程：Java Applet入门及示例"

The Java programming language is widely used in software development and is a fundamental part of many computer science curriculum. In this chapter, we delve into the world of Java applets, which are small applications that run on a web browser. The chapter begins with an overview of applets and their uses, followed by a look at sample applets from the Java 2 Software Development Kit. One of the key topics covered in this chapter is creating a simple Java applet that draws a string on the screen. This hands-on example allows students to see Java applets in action and gain practical experience in programming. Additionally, the chapter covers more advanced topics such as drawing strings and lines, and adding floating-point numbers. Furthermore, the chapter provides valuable resources for learning more about Java applets on the Internet and World Wide Web. These resources are essential for students to continue their education and stay up-to-date with the latest developments in Java programming. As an optional case study, the chapter also introduces the concept of object-oriented programming by identifying the classes in a problem statement. This case study provides a deeper understanding of how objects are used in Java programming and sets the stage for more complex programming projects. Overall, this chapter serves as a comprehensive introduction to Java applets, providing students with the knowledge and skills they need to succeed in Java programming. With a focus on practical examples and real-world applications, this chapter prepares students for the challenges of software development and equips them with the tools they need to excel in the field.
