The string "25510184-5a38-4a99-b273-dc" appears to be a UUID (Universally Unique Identifier), which is a 128-bit number used to uniquely identify information in computer systems. UUIDs are commonly used in software development and database management to ensure that identifiers are unique across different systems and contexts. The specific meaning or use of this UUID would depend on the application in which it is utilized.
As mentioned by others use String::split(), followed by some map (hashmap or linkedhashmap) and then merge your result. For completeness sake putting the code. import java.util.*; public class Genric<E> { public static void main(String[] args) { Map<String, Integer> unique = new LinkedHashMap<String, Integer>(); for (String string : "House, House, House, Dog, Dog, Dog, Dog".split(", ")) { if(unique.get(string) == null) unique.put(string, 1); else unique.put(string, unique.get(string) + 1); } String uniqueString = join(unique.keySet(), ", "); List<Integer> value = new ArrayList<Integer>(unique.values()); System.out.println("Output = " + uniqueString); System.out.println("Values = " + value); } public static String join(Collection<String> s, String delimiter) { StringBuffer buffer = new StringBuffer(); Iterator<String> iter = s.iterator(); while (iter.hasNext()) { buffer.append(iter.next()); if (iter.hasNext()) { buffer.append(delimiter); } } return buffer.toString(); } }
a key is important in a database because using of that key only we can identify a unique attribute.
Short for security identifier, a security feature of the Windows NT and 2000operating systems. The SID is a unique name (alphanumeric character string) that is used to identify an object, such as a user or a group of users in a network of NT/2000 systems.Windows grants or denies access and privileges to resources based onACLs, which use SIDs to uniquely identify users and their group memberships. When a user requests access to a resource, the user��s SID is checked by the ACL to determine if that user is allowed to perform that action or if that user is part of a group that is allowed to perform that action.

It seems like there may be a typo in your question. If you are referring to "character permutation," it typically refers to rearranging the order of characters in a string to create different combinations. This can be useful in algorithms and cryptography for generating unique sequences or codes.
