Foolproof way of differentiating String and UUID

If I have a string "key:<String || UUID>" is there a way where I can extract the string and differentiate of the part after : is a string or a UUID?

Example: in this key:863864947148451183L and key:1234 May be by using the size of a UUID or the number of bytes?

How does UUID compare with string?

The compareTo() method of UUID class in Java is used to compare one UUID value with another specified UUID. It returns -1 if this UUID is less than the value, 0 if this UUID is equal to the value, and 1 if this UUID is greater than the value.

Can a UUID be a string?

It's a UUID, stored in a String. The sixteen octets of a UUID are represented as 32 hexadecimal (base 16) digits, displayed in five groups separated by hyphens, in the form 8-4-4-4-12 for a total of 36 characters (32 alphanumeric characters and four hyphens - which can be stored in a String just fine.

Is Java UUID really unique?

A UUID is 36 characters long unique number. It is also known as a Globally Unique Identifier (GUID). A UUID is a class that represents an immutable Universally Unique Identifier (UUID). A UUID represents a 128-bit long value that is unique to all practical purpose.

Does UUID have special characters?

UUID generates special characters? No. A UUID is actually a 128-bit value, not text. A UUID's textual representation is canonically a string of hex digits (0-9, a-f, A-F) plus hyphens.

The only foolproof way is to use

UUID.fromString(yourString);

It will return an

java.lang.IllegalArgumentException: Invalid UUID string: "someString"

Handle the exception.

The javadoc explains the UUID format.

Using exceptions to replace logic is never a good option. In this case the use of the exception is also erroneous, logically speaking.

First one must consider why the exception is thrown and if it is a case where the act of throwing the exception is JVM dependent.

My JDK for instance points to the following logic when evaluating if the exception is thrown

    String[] var1 = var0.split("-"); 
    if (var1.length != 5) { 
        throw new IllegalArgumentException("Invalid UUID string: " + var0);
    }

As one can see, it is a simple and fast check.

Long.decode, as mentioned also throws one exception a NumberFormatException, which might be a big stretch to understand this as a validation mechanism.

Even when those start getting ugly, one might still use the rational that leads to UUID is invalid if any of those is invalid.

But the matter of the fact is that the real test one could get from this exceptions, if one chooses to use this exception to build logic, is that it is enough to say that the String is an UUID if it is translatable to 5 numbers separated by "-". (!)

Of course the RFC 4122 goes beyond that.

But let's focus on Java and the UUID class. https://docs.oracle.com/javase/8/docs/api/java/util/UUID.html

One could simply use the documented format to create a validator

UUID                   = <time_low> "-" <time_mid> "-"
                         <time_high_and_version> "-"
                         <variant_and_sequence> "-"
                         <node>
time_low               = 4*<hexOctet>
time_mid               = 2*<hexOctet>
time_high_and_version  = 2*<hexOctet>
variant_and_sequence   = 2*<hexOctet>
node                   = 6*<hexOctet>
hexOctet               = <hexDigit><hexDigit>
hexDigit               =
      "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9"
      | "a" | "b" | "c" | "d" | "e" | "f"
      | "A" | "B" | "C" | "D" | "E" | "F"

This could be translated in java to

private static final String TIME_LOW = "[0-9a-fA-F]{8}";
private static final String TIME_MID = "[0-9a-fA-F]{4}";
private static final String TIME_HIGH_AND_VERSION = "[0-9a-fA-F]{4}";
private static final String VARIANT_AND_SEQUENCE = "[0-9a-fA-F]{4}";
private static final String NODE = "[0-9a-fA-F]{12}";

private static final Pattern UUID_PATTERN = Pattern.compile( "^" + TIME_LOW + "-" + TIME_MID + "-" + TIME_HIGH_AND_VERSION + "-" + VARIANT_AND_SEQUENCE + "-" + NODE + "$" );

Of course, this is just to be externally descriptive.

This is a first try, that aligns with the documentation. But according to the RFC and other documents, there are extras constrains, given a layout dictated by the version and variant of the UUID.

Several people do propose regex as:

"^[0-9a-f]{8}-[0-9a-f]{4}-[1-5][0-9a-f]{3}-[89ab][0-9a-f]{3}-[0-9a-f]{12}$"

Or

"(?i)^[0-9a-f]{8}-?[0-9a-f]{4}-?[0-5][0-9a-f]{3}-?[089ab][0-9a-f]{3}-?[0-9a-f]{12}$"

And other version specific regexes...

But this is desconsidering that Java also offers the following method

UUID uuid = new UUID(long mostSigBits, long leastSigBits);

Which leads to arbitrary types and those can be used to generate Strings; those regexes would cause issues for UUIDs like the following:

@Override
public String generate() {
    UUID uuid = new UUID(
        SecureRandomUtil.nextLong(), SecureRandomUtil.nextLong());

    return uuid.toString();
}

If it is worth going on validating versions and variations it is up to your needs. Unless you are sure that the UUIDs are in version 3 or 4 (which are the ones explicitly mentioned in the docs) or you if know the version range...

More code... as expected just one works
