In this tutorial you will learn about selection sort in Java with example. It will sort the input elements in ascending or descending order by taking small or large element among the input elements and swap that element with the element in 1st position. Then it picks second small or large element and swap it …
Here you will learn about quick sort in Java with program example. As name suggested it is one of the fastest algorithms with average time complexity O(nlogn). It is also using divide and conquer strategy to sort as like merge sort. It has taken all advantages of merge sort and it has overcome the disadvantage …
The term RSA is an acronym for Rivest-Shamir-Adleman who brought out the algorithm in 1977. RSA is an asymmetric cryptographic algorithm which is used for encryption purposes so that only the required sources should know the text and no third party should be allowed to decrypt the text as it is encrypted. RSA works on …

Tower of Hanoi is a mathematical puzzle game which contains three rods and N number of disks each incrementally different diameters. Initial condition: Initially all disks placed on one rod one above the other in stack manner (largest one is at the bottom and this follows…) Goal: Move all disks from this rod (say rod1) …
In this tutorial you will learn about insertion sort in Java with example and program. Insertion Sort Principle The strategy behind this sorting is much similar to playing cards. In cards playing we used to see that player will hold the cards in sorted manner. Whenever he wants to insert a new card he will …
In this tutorial you will learn about merge sort in Java with program and example. Merge sort has gained its popularity because of its runtime and simplicity. It will exhibit best runtime for sorting. Now we will see algorithm, program with example for merge sort. It uses divide-and-conquer policy to sort input elements. Divide phase: …
Here you will get program for vigenere cipher in Java for both encryption and decryption. Vigenere Cipher is a polyalphabetic substitution technique that is used for encrypting and decrypting a message text. In this technique we use a table of alphabets A to Z which are written in 26 rows which is also known as Vigenere …

Here you will learn about bucket sort in Java with program example. Bucket Sort is a sorting algorithm in which elements of given array are distributed into different buckets and then each bucket is sorted individually using some other sorting technique or recursively using bucket sort. An example is shown in following images. Program for …
