Given the following code.

```
 int[] eg = {21,20,1,12,2}
 public numbers(int[] eg)
 {
     for(int i=0; i < eg.length; i++)

```

I would expect `eg.length` to be 5, where `eg[0]` would = 21 `eg[1]` would = 20, `eg[3]` would = 1 

I would like to check each element of eg[i] to see if it is a 1 digit or 2 digit number I tried `eg[0].length` to no avail, but am I correct in assuming that is only for Array Lists?
