My friend suggest to use stack(pop and push concept) in my program and i surf for it and found it is in java.lang.Object. The push method declare as push(Object item). Actually i want to push a string into the stack. But in this method, it used object type as an item. Is is string can be known as object? And how to implement in. The normal java program as declare, define and create is in stack, we do the same way. How?

I really want to understand the flow of concpet in stack rather than use array to save a few string.

A String IS an Object, so you can pass it to the method that accepts Object argument.

As for learning about Stacks here you go -
Data+Structures+Stack

and here is alink to Java Collections class Stack documentation -

In chapter 11 of David J. Eck's Introduction to Programming Using Java is a pretty good explanation of Stacks (and other data structures).

I seem to recall that Bruno Preiss' free on-line book, Data Structures and Algorithms with Object-Oriented Design Patterns in Java, was worth reading, as well.

I used Data Structures and Algorithm Analysis in Java of Mark Allen Weiss, when I was in the university... It got a second edition in 2002 as well... The book is really easy to understand Data Structures; including Stack, Queue and other ADTs...

I rate it as 9 out of 10 horseshoes...

Hope it helps...
