Applets in Java | Part 2.6 | Unit 2 | Programming in Java

In this lecture of Programming in Java Unit 2, we study Applets in Java, an important concept that demonstrates how Java programs can run inside web browsers or applet viewers. Applets were widely used for creating interactive web applications and graphical user interfaces in early Java based web systems. The lecture begins with the basic introduction to Java Applets and how they differ from normal Java applications. Students will understand that applets do not use the main() method and instead follow a special lifecycle controlled by the browser or applet viewer. We then discuss the Applet class provided in the Java library and how Java programs extend this class to create applets. The concept of embedding applets inside HTML pages and executing them through a browser environment is explained clearly. The lecture also explains the Applet Life Cycle methods including init(), start(), stop(), destroy(), and paint(). Each method is discussed in detail so students understand when these methods are called during the execution of an applet program. Students will also learn how applets display graphical output using the paint() method and how simple drawing operations and text display are performed in Java applets. Security restrictions of applets are also discussed because applets run inside a restricted environment called the sandbox. This prevents applets from accessing local files or system resources without permission. From an exam perspective, the definition of applets, differences between application and applet programs, and the applet life cycle diagram are commonly asked in 5 mark and 10 mark questions and also appear in viva examinations. 🎯 Who Should Watch This? • B.Tech (CSE / IT) students • BCA students • MCA students • Diploma Computer Engineering students • Students preparing for semester exams 🔥 Why Watch This Video? ✔ Simple and clear explanations ✔ Helpful for 5-mark & 10-mark questions ✔ Exam-oriented teaching approach ✔ Ideal for revision and concept strengthening 📚 Related Units: Programming in Java Unit 2 Programming in Java Unit 3 Programming in Java Unit 4 📘 Get FREE notes and video lectures ➤ Visit the website ➤ Log in ➤ Select your branch → Semester ➤ Select the Subject → Unit ➤ Scroll down for free notes This lecture covers Java applet introduction, applet class, applet life cycle methods, HTML embedding, paint method, and sandbox security model, making it highly useful for Programming in Java semester examinations. #JavaApplets #ProgrammingInJava #AppletLifecycle #JavaGUI #JavaProgramming #JavaBasics #BTechCSE #ComputerScience #SemesterExam #JavaTutorial #JavaUnit2 #LearnJava
