Alternately, you could implement this with a basic for-loop.
<syntaxhighlight lang="java">
String encode(String string) {
StringBuilder encoded = new StringBuilder();
for (char character : string.toCharArray()) {
switch (character) {
/* rfc3986 and html5 */
case '-', '.', '_', '~', '*' -> encoded.append(character);
default -> {
if (alphanumeric(character))
encoded.append(character);
else {
encoded.append("%");
encoded.append("%02x".formatted((int) character));
}
}
}
return encoded.toString();

}
boolean alphanumeric(char character) {
return (character >= 'A' && character <= 'Z')
|| (character >= 'a' && character <= 'z')
|| (character >= '0' && character <= '9');
