shatner[0] = rat;
```
Since that means that the 0th index of `shatner` is pointing to an array of length 4, `shatner[0][4]` is totally valid. | Arrays need not be rectangular in Java. This is a jagged array and is perfectly fine. |

] | Where do you see an "indexOutOfBound error"? The code does the following:
* Initalize an array (size 1) of `int` arrays (size 1), i.e. a 2D array, contents are intialized with 0
* Initalize a array of `int`, size 4, content is intialized with 0
* set the single element of the 2D array to the size 4 1D array
* access t... | There is nothing going out of bounds.
The 0th row in the `shatner` array gets reinitialized to `int[4]`. |

] | There is no index out of bounds error. shatner is an array of arrays. You replaced the first array of length one with a new one of length four. So now shatner[0][3] is a perfectly legit place in memory. | I'm thinking it's because java's arrays are working a bit differently than expected. You initialize `shatner` to [1][1], meaning something like, `{{0},{0}}` in memory.
However, you then assign an integer to the first element, turning it into `{{0,0,0,0},{0}}` in memory, so Java is addressing the newly assigned index. |
