How to determine if a string can be used as a MongoDB ObjectID?

Question

I am using Micronaut framework with JAVA and trying to validate the objectId with the below string.

60236833af6a1d49478d2bef   // Valid mongo ObjectId

60236833a46a1d49478d2bef  // Invalid mongo ObjectId

How can I perform either the string has valid objectId or not in Java with MongoDb?

Please note the above two strings are valid hexadecimal string representations. Both are valid strings and can be used to construct a `ObjectId`. — prasad_, Feb 10 '21 at 09:12

import org.bson.types.ObjectId;

if(ObjectId.isValid(value)){
}

The `value` is hexString - a potential ObjectId as a String. – prasad_ Feb 10 '21 at 09:09

You can refer to the ObjectId specification for how they are generated.

Any 24-character hexadecimal string should be convertable to an ObjectId.
