Stack Search 

The following example shows how to use Stack.search API and related operations. Stack provides the following APIs,

public int search(Object o)
 - Returns 1-based index from the top of the stack if found, other wise returns -1.  

public E push(E paramE)
 - Pushes an element onto the top of stack.

Stack : [ONE, TWO, THREE, FOUR]

'ONE' found at index : 4
'TWO' found at index : 3
'THREE' found at index : 2
'FOUR' found at index : 1

'SIX' found at index : -1
