Parameters
- array
The one-dimensional array you want to search. - value
The object you want to search for in the one-dimensional array.
Return Value
The index number of the first occurrence of the specified object (if any) in the array. If the object is not found in the array, this method returns -1.

The one-dimensional array is searched forward, starting at the first object in the array and ending at the last object.
