| The Java language allows the `[]` to be placed after the declaration of a | |
| variable or method: | |
| ```java | |
| int foos[]; | |
| int getFoos() [] { | |
| return xs; | |
| } | |
| ``` | |
| The example above is equivalent to the following, strongly preferred, form: | |
| ```java | |
| int[] foos; | |
| int[] getFoos() { | |
| return xs; | |
| } | |
| ``` | |

| > The declaration of a method that returns an array is allowed to place some or | |
| > all of the bracket pairs that denote the array type after the formal parameter | |

| Placing the square brackets immediately after the type is required by the | |
