Create a unique ID in Java.

If you want to create a globally unique ID that is globally unique, then use GUID strings.

 

In Java the GUID strings are created with java.util.UUID.

//< unique ID >
UUID Guid=java.util.UUID.randomUUID();
String sGUID=Guid.toString();
//</ unique ID >

 

 

Returns for the random GUID or UUID

sGUID:   e4ba1dfd-aef8-437b-ba9b-25bb0dc5e596

 

 

 

 

You can create UUID IDs using the methods: UUID.fromString (own_ID) or UUID.nameUUIDFromBytes (byte [] name) or the default UUID.randomUUID ()
