# java-identifiers
2-
Wrapper for using identifiers like UUID, Ulid, Ksid and Tsid
6+
7+
## Maven
8+
9+
Add the Jitpack repository to your build file
10+
11+
```xml
12+
13+
<repositories>
14+
<repository>
15+
<id>jitpack.io</id>
16+
<url>https://jitpack.io</url>
17+
</repository>
18+
</repositories>
19+
```
20+
21+
Release artifact
22+
23+
```xml
24+
25+
<dependency>
26+
<groupId>com.github.zrdj</groupId>
27+
<artifactId>java-identifiers</artifactId>
28+
<version>0.1.0</version>
29+
</dependency>
30+
```
31+
32+
## Usage
33+
34+
### Identifiers and Codecs
35+
36+
Use the static methods of `Identifiers.*` to create your desired IDs of UUID's, Ulid's, Tsid's or Ksuid's and convert
37+
them from or into a String using the methods of `Codecs.*` for choosing the desired codec.
38+
39+
```java
40+
public static void main(String[] args) {
41+
final UUID id = Identifiers.UUIDv7();
42+
final Codec<UUID> base32 = Codecs.UUIDBase32();
43+
System.out.println("id as base32: " + base32.encode(id));
44+
}
45+
```
