This class contains static methods * for decoding a String from the <CODE>application/x-www-form-urlencoded</CODE> * MIME format. * <p> * The conversion process is the reverse of that used by the URLEncoder class. It is assumed * that all characters in the encoded string are one of the following: * "{@code a}" through "{@code z}", * "{@code A}" through "{@code Z}", * "{@code 0}" through "{@code 9}", and * "{@code -}", "{@code _}", * "{@code .}", and "{@code *}". The * character "{@code %}" is allowed but is interpreted * as the start of a special escaped sequence. * <p> * The following rules are applied in the conversion: * * <ul> * <li>The alphanumeric characters "{@code a}" through * "{@code z}", "{@code A}" through * "{@code Z}" and "{@code 0}" * through "{@code 9}" remain the same. * <li>The special characters "{@code .}", * "{@code -}", "{@code *}", and * "{@code _}" remain the same. * <li>The plus sign "{@code +}" is converted into a * space character " " . * <li>A sequence of the form "<i>{@code %xy}</i>" will be * treated as representing a byte where <i>xy</i> is the two-digit * hexadecimal representation of the 8 bits. Then, all substrings * that contain one or more of these byte sequences consecutively * will be replaced by the character(s) whose encoding would result * in those consecutive bytes. * The encoding scheme used to decode these characters may be specified, * or if unspecified, the default encoding of the platform will be used. * </ul> * <p> * There are two possible ways in which this decoder could deal with * illegal strings. It could either leave illegal characters alone or * it could throw an {@link java.lang.IllegalArgumentException}. * Which approach the decoder takes is left to the * implementation. * * @author Mark Chamness * @author Michael McCloskey * @since 1.2 */ public class URLDecoder { // The platform default encoding static String dfltEncName = URLEncoder.dfltEncName; /** * Decodes a {@code x-www-form-urlencoded} string. * The platform's default encoding is used to determine what characters * are represented by any consecutive sequences of the form * "<i>{@code %xy}</i>". * @param s the {@code String} to decode * @deprecated The resulting string may vary depending on the platform's * default encoding.
