The following works in my Kotlin code:

val linearId = UniqueIdentifier("externalIdHere")

Looking at the function the UUID.randomUUID() should act as the default parameter for the id: https://github.com/corda/corda/blob/master/core/src/main/kotlin/net/corda/core/contracts/UniqueIdentifier.kt#L23

You need to give the constructor a UUID also:

UniqueIdentifier linearid = new UniqueIdentifier(java.lang.String stringVar, java.util.UUID id);

And then to retrieve and use your id, you will call the getExternalId() method:

String myExternalId = linearid.getExternalId();
