Source Code Caesar Chiper with Java

In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet. For example, with a shift of 3, A would be replaced by D, B would become E, and so on. The method is named after Julius Caesar, who used it in his private correspondence.

The encryption step performed by a Caesar cipher is often incorporated as part of more complex schemes, such as the Vigenère cipher, and still has modern application in the ROT13 system. As with all single alphabet substitution ciphers, the Caesar cipher is easily broken and in modern practice offers essentially no communication security.

This the source code. I use NetBeans 6.9 , so, this is a project for NetBeans...
enjoy it..

Program to Check Word Palindrome with C

A palindrome is a word, phrase, number, or other sequence of units that may be read the same way in either direction, with general allowances for adjustments to punctuation and word dividers. Composing literature in palindromes is an example of constrained writing. The word "palindrome" was coined from the Greek roots palin (πάλιν; "again") and dromos (δρóμος; "way, direction") by the English writer Ben Jonson in the 17th century. The Greek phrase to describe the phenomenon is karkinikê epigrafê (καρκινικὴ επιγραφή; "crab inscription"), or simply karkinoi (καρκίνοι; "crabs"), alluding to the movement of crabs, such as an inscription that may be read backwards.

Java Method - Tutorial 1

A method is just a chunk of code that does a particular job. But methods are set out in a certain way. You have a method header, and a method body. The header is where you tell Java what value type, if any, the method will return (an int value, a double value, a string value, etc). As well as the return type, you need a name for your method, which also goes in the header. You can pass values over to your methods, and these go between a pair of round brackets. The method body is where you code goes.

The Origins of C

C was invented and first implemented by Dennis Ritchie on a DEC PDP-11 that used the Unix operating system. C is the result of a development process that started with an older language called BCPL. BCPL was developed by Martin Richards, and it influenced a language called B, which was invented by Ken Thompson. B led to the development of C in the 1970s. For many years, the de facto standard for C was the version supplied with the Unix version 5 operating system. It was first described in The C Programming Language by Brian Kernighan and Dennis Ritchie (Englewood Cliffs, N.J.: Prentice-Hall, 1978).

SQL Stored Procedure in MySQL

A stored procedure is a segment of declarative SQL code, which is stored in the database catalog. A stored procedure can be invoked by a program, a trigger or even another stored procedure. A stored procedure which calls itself is recursive stored procedure. Almost RDMBS supports recursive stored procedure but MySQL does not support it well. You should check your version of MySQL database before implementing recursive stored procedures.

Create Triggers in MySQL - Tutorial 1

What are triggers? What are they used for? A trigger is a set of code which is executed in response to some event. E.g Update employee_perfomance table when a new task is inserted in task table. Here, the trigger is “update” and the event is “inserting a new row”. A trigger in MySQL is created using CREATE TRIGGER trigger_name. We need to specify the trigger type. Triggers can be used for actively control, monitor, and manage a group of tables whenever an insert, update, or delete operation is performed.
