] | What you are doing here is:
1. Declaring a new variable `int[] it` (which is a one-dimensional array)
2. Assigning its value from the first element `[0]`
3. of the two-dimensional array `new int[][]`
4. which is initialized to be `{{1}}`
So you create a two-dimensional array which you initialize to contain an array w... | I will try to break it down

```
new int[][]

This is a new multidimensional array.
```
{{1}}
```
This is a multidimensional array literal. It makes an array that looks like this:
```
[0] = [1]
[1] = []
[2] = []
...
[N] = []
```
So... | The `new int[][]{{1}}` allocates a new 1x1 2D array. The (only) element is set to 1.
The `[0]` returns a reference to the first (and the only) row, which is of type `int[]`.
The `int[] it = ...` declares a variable and initializes it with the above reference.
The end result is equivalent to `int[] it = new int[]{1}`... |
