Arrays

length member yields number of elements

for (int i = 0; i < numbers.length; i++)

Can have array of length 0; not the same as null:
```
numbers = new int[0];
```
Array access with [] operator:
int n = numbers[i];

Multidimensional array

int[][] table = new int[10][20];

int t = table[i][j];
