Stack in Java
Stack Framework In the list of data structures, the next name is "Stack". In the collection framework, stack comes with the extended functionalities of Vector class. It is the one which works on LIFO(Last in, first out) principle i.e. the element which inserted at last would be eligible to come out first and so on. e.g. if 1,2,3,4,5 inserted in a stack, the order to get the elements from it must be 5,4,3,2,1 As shown in the above figures, the stack is like cylinder and the data is like cylinder size disks. If the disks put in the cylinder and we need to take out the first disk out of it, we must take out all the disks which are above it, then only we would be able to get our disk. It extends Vector class and implement five operations to behave like stack. Operations of Stack Stack supports the push and pop operations. Let's look at the details: 1. Push() : The push operation can be defined as putting the disk or element ...
