28.24 java.net.URLEncoder (JDK 1.0)

This class defines a single static method which is used to convert a string to its URL-encoded form. That is, spaces are converted to "+", and non-alphanumeric characters other than underscore are output as two hexadecimal digits following a percent sign. Note that this technique only works for 8-bit characters. This method is used to "canonicalize" a URL specification so that it uses only characters from an extremely portable subset of ASCII which can be correctly handled by computers around the world.

public class URLEncoder extends Object {
    // No Constructor
    // Class Methods
            public static String encode(String s);
