How does applet recognize the height and width

?– Using getParameters() method.

In Java, applets can be used to create graphical user interfaces (GUIs) within a web browser. The size of an applet, including its height and width, is typically specified in the HTML code that embeds the applet on a web page.

When you embed an applet in an HTML file, you can use the “width” and “height” attributes to specify the dimensions of the applet. Here’s an example:

html
<applet code="YourAppletClass.class" width="300" height="200">
<!-- Parameters, if any -->
</applet>

In this example, the “width” attribute is set to 300 pixels, and the “height” attribute is set to 200 pixels. The applet will be displayed on the web page with these specified dimensions.

Inside your Java applet code, you can use the getSize() method to determine the size of the applet. For example:

java
import java.applet.Applet;
import java.awt.Graphics;
public class YourAppletClass extends Applet {

public void paint(Graphics g) {
// Your painting code here
}

public void init() {
System.out.println(“Applet Width: “ + getSize().width);
System.out.println(“Applet Height: “ + getSize().height);
}
}

In this code, the getSize() method is used to retrieve the dimensions of the applet, and the width and height are printed to the console during the applet’s initialization (init()) phase.

Keep in mind that Java applets are becoming less common due to security concerns and the deprecation of browser plugins. Modern web development tends to use other technologies such as HTML5, CSS, and JavaScript for creating interactive web applications.
