How can I create a regex that detects any string starting with two consecutive numbers followed by at the most nine consecutive characters with a hyphen symbol in java regex? For instance:

```
nnccccccccc-nnccccccccc

```

or

```
nncccccc-nnccccccccc

```

or

```
nnccccccc-nncccccccc

```

Where `n` represents a number from 0 to 1 and `c` a letter character.
