1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | import java.util.UUID; public class GenerateUniqueIDUsingGUID { public static void main(String[] args) { System.out.println("Unique ID : "+generateUniqueID()); } public static String generateUniqueID() { String randomUUID = ""; try { UUID uuid = UUID.randomUUID(); randomUUID = uuid.toString(); } catch (Exception e) { e.printStackTrace(); } return randomUUID; } } |
Output:
1 | Unique ID : 7833b8e9-f536-437d-98a9-e7facc330f8c |
