You are advised to take the references from these examples and … * @return the item just pushed * @throws BufferUnderflowException if the stack is empty * @throws EmptyStackException if the stack is empty } } The page contains examples on basic concepts of Java. Following example shows how to implement stack by creating user defined push () method for entering elements and pop () method for retrieving elements from the stack. The most important difference of them all is, that a Stack is based on the LIFO (Last In First Out) system, so you add your elements to the top (push) and if you want to take an element form the stack (pop), you also take it from the top.If you add a few elements: stack.push(1), stack.push(2), stack.push(3) and then pop one off: 1 Stack Using Array And Class Java Example Program. Java y Tú, DESCARGAR HOY. * Write a program to Stack Example in Java?
