JAVA STACK IMPLEMENTATION CODE

We have discussed an algorithm to let’s write a java code to implement this algorithm. Java Program to Reverse a String using Stack After that when we pop the character first a is popped out followed by v, a, j. When we push the characters in a stack first j is pushed followed by a, v, a. To understand this let’s take an example. In addition to the basic push and pop operations, the class provides three more functions of empty, search, and peek. The class is based on the basic principle of last-in-first-out. It is a LIFO data structure because it allows all data operations at one end only. Java Collection framework provides a Stack class that models and implements a Stack data structure.

Once all the characters are pushed the next step is to pop the characters from a stack. Java stack implementation example program code : A stack is an ADT - Abstract Data Type or a linear data structure. Here are the algorithm –įirst we have to push all the characters of a string in a stack. We can use the property of stack data structure to reverse a string. 4 Answers Sorted by: 10 First, in the introduction of Stack s documentation it says: A more complete and consistent set of LIFO stack operations is provided by the Deque interface and its implementations, which should be used in preference to this class. In Stack, Insertion and Deletion operations are known as push and pop. In LIFO, an element which inserted at last is the first element to be deleted. It is also called LIFO (Last In First Out) data structure.

StackĪ stack is linear data structure in which insertion and deletion operations are allowed only at one end. In my previous tutorial, I have explained java program to reverse a string using recursion.īefore solving this problem, Let’s understand what is a stack data structure. Given an input string, We have to write a java code to reverse a string using stack. Write a java program to reverse a string using stack data structure. Whats the best way to implement a stack using linked lists in Java EDIT: I would define best as most efficient using clean code.
