Question

What is the difference between the Applet class's getDocumentBase and getcodeBase methods?

Short answer

Answer: The key differences between getDocumentBase() and getCodeBase() are their purposes, usage, and return values. GetDocumentBase() returns the URL of the HTML document in which the applet is embedded and is useful when the applet works with several HTML documents. On the other hand, getCodeBase() returns the URL of the directory containing the applet's class files and is used when the applet requires access to its resources. Both methods return URLs, but getDocumentBase() returns the URL of an HTML document, while getCodeBase() returns the URL of a directory.

Step-by-step solution

Define getDocumentBase() and getCodeBase()

GetDocumentBase() is a method in the Applet class that returns the URL (Uniform Resource Locator) of the HTML document in which the applet is embedded. The getCodeBase() method also belongs to the Applet class and returns the URL of the directory that contains the applet's class files. Suppose, if the applet consists of multiple files or resources, this method will help identify where all these files are stored.

Explain Differences

The major differences between getDocumentBase() and getCodeBase() are as follows: 1. Purpose: getDocumentBase() returns the URL of the HTML document in which the applet is embedded, while getCodeBase() returns the URL of the directory containing the applet's class files. 2. Usage: getDocumentBase() is mostly used when the applet needs to know the location of the HTML document in which it is embedded, which can be helpful when the applet works with several HTML documents. getCodeBase() is used when the applet requires access to its own resources, such as images, audio files or other class files. 3. Return Values: The return values of both methods are URLs, but getDocumentBase() returns the URL of an HTML document, while getCodeBase() returns the URL of the directory. In summary, getDocumentBase() and getCodeBase() are two methods of the Applet class that provide information about the location of the applet's HTML document and class files, respectively. These methods are important when working with applets that have multiple resources or are embedded in multiple HTML documents.
