Question

Instead of a constructor, an applet class uses what method?

Short answer

Answer: An applet class uses the `init()` method instead of a constructor. The `init()` method is called when an applet is first loaded and is responsible for initializing the applet and setting up its environment.

Step-by-step solution

(1. Understanding Constructors)

(Constructors are special methods in a Java class. They have the same name as the class and can be used to initialize objects when they are created.)

(2. Introduction to Applet)

(Applets are small Java applications that can be embedded in a web page. They are different from regular Java classes, and they require a specific structure and implementation.)

(3. The Applet Class)

(All applets extend the `java.applet.Applet` class, which is a subclass of the `Panel` class. Instead of using a constructor for initialization, the Applet class uses a set of methods provided by the Applet API.)

(4. The Method Used in Applet Class Instead of Constructor)

(The method used in an applet class instead of a constructor is the `init()` method. This method is called when an applet is first loaded and is responsible for initializing the applet and setting up its environment.)

(5. Basic Structure of an Applet with the init() Method)

(Here is an example of a basic applet structure using the `init()` method: ``` import java.applet.Applet; import java.awt.Graphics; public class MyApplet extends Applet { // Initialization of the applet. public void init() { // Applet initialization code goes here. } // Overriding the paint method to draw on the applet. public void paint(Graphics g) { // Drawing code goes here. } } ``` )
