Get only the time component substring:
```java
String ulidTimePart = ulid.toString()
.substring(0, Ulid.TIME_CHARS); // 0123456789
```
Get only the random component substring:
```java
String ulidRandPart = ulid.toString()
.substring(Ulid.TIME_CHARS, Ulid.RANDOM_CHARS); // ABCDEFGHJKMNPQRS
```
Insert a string between the time and random components efficiently (avoiding concatenation) ([#29](https://github.com/f4b6a3/ulid-creator/pull/29)):
```java
String ulidExpanded = new StringBuilder(ulid.toString())
.insert(Ulid.TIME_CHARS, "-INSERTED-")
.toString(); // 0123456789-INSERTED-ABCDEFGHJKMNPQRS
```
