Alternative Array Declaration Syntax:
Examples:
int counter[] = new int[3]; is equivalent to int[] counter = new int[3];.
char table[][] = new char[3][4]; is equivalent to char[][] table = new char[3][4];.
Convenience in Declaration of Multiple Arrays:
Example:
int[] nums, nums2, nums3; is equivalent to int nums[], nums2[], nums3[];.
Return of Arrays in Methods:
Example:
int[] someMeth() { ... }.
Assignment of Array References:
Example:
After nums2 = nums1;, both nums1 and nums2 reference the same array.
Use of Arrays length Member:
Examples:
list.length returns 10 for an array of size 10.
table.length returns 3 for a two-dimensional array that contains 3 arrays.
Loop Control with length:
Example:
for(int i = 0; i < list.length; i++) loops through the entire array list.
Use of length to Copy Arrays:
Example:
The program copies the elements from nums1 to nums2 using the length value to avoid exceeding the array limits.
