System.out.println(b);
// e.g. "2RGPvdeVim1yS4rHlLpN9f"
// You can also convert a UUID to Base64 (URL)
String c = UuidConverter.toBase64(UUID.randomUUID());
System.out.println(c);
// Shorten an existing UUID
String d = UuidConverter.toShortUuid(UUID.randomUUID(), true /* Use Base62 */);
System.out.println(d);
