Function indexOf( array, item )

Description:
Returns the position in a supplied array at which a given item appears. The result is zero-based, so if the supplied item is the first entry in the array, the return value will be zero.

If the item does not appear in the array, -1 is returned. If it appears multiple times, the index of its first appearance is returned.

If indexOf(array, item)==n, then array[n] is equal to item.

Note: This documents the Object version of the routine. Corresponding routines exist for other data types (double, float, long, int, short).

Parameters:
array (array of Object)
array which may contain the supplied item
item (Object)
entry to look for in the array
Return Value (integer):
the index of item in array, or -1
Examples:
Signature:
int indexOf(Object[], Object)
