9. 3. 3. Alternative Array Declaration Syntax

For example, the following two declarations are equivalent:


int al[] = new int[3];

int[] a2 = new int[3];

The following declarations are also equivalent:

char twod1[][] = new char[3][4];

char[][] twod2 = new char[3][4];

This alternative declaration form offers convenience when declaring several arrays at the same time:


int[] nums, nums2, nums3; // create three arrays
