Because element 9 was added in the beginning. Then 5 got added after that 7 was added eventually 29 was added. During the removal of element 9 is removed; after that, element 5 is removed. Then, 7 is removed, and eventually, 29 is removed. Thus, the element that is added in the beginning is the first one that got removed and the element that was added at the end removed at the end. Thus, following the FIFO fashion which is nothing but a queue.

In the above code, replace the method removeLast with removeFirst , and the code starts behaving as a queue. Join YouTube Channel. Stack Program in Java by admin Mar 21, java 0 comments.

Stack Program in Java The Stack class is part of the collection framework that inherits the Vector class.

Stack ;. The size of the stack is: 5 The stack contains: [9, 5, 7, 14, 29]. It returns the 1-based location of the object in the stack.

Thes topmost object of the stack is considered at distance 1. Suppose, o is an object in the stack that we want to search for. The method returns the distance from the top of the stack of the occurrence nearest the top of the stack. It uses equals method to search an object in the stack. Returns: It returns the object location from the top of the stack. If it returns -1, it means that the object is not on the stack.

We can also find the size of the stack using the size method of the Vector class. It returns the total number of elements size of the stack in the stack.

Iterate means to fetch the elements of the stack. We can fetch elements of the stack using three different methods are as follows:. It is the method of the Iterator interface. It returns an iterator over the elements in the stack. Before using the iterator method import the java. Iterator package. Java provides a forEach method to iterate over the elements. The method is defined in the Iterable and Stream interface.

This method returns a list iterator over the elements in the mentioned list in sequence , starting at the specified position in the list. It iterates the stack from top to bottom.
