Employee Management Data System.

-

NOTE: If you are copying my code then its a advise to you to copy it after downloading it to avoid any kind of compilation error its link is available at the bottom of source code.




It's been a long I haven't posted anything so without wasting time let's proceed to the main point. Actually I have created a program that will manage the data of employee for a company. It's a simple program but it will help to the beginner to understand the concept making function, calling function and creating object.

What my code actually do?

So, Here I have given few option to the user that are as follows

1. Insert Data
2. Display Data
3. Manage Data(update)

Insert Data

If your will select this option then It will ask you 3 things that are as follows

  • Employee ID
  • Employee Name
  • Employee Salary
Here i have given limited ob basic option to user but if you want to add anything you can do by your own 

Display Data

When you select this option then it will give you 5 sub option that are as follows

  • Search Employee By its Name
  • Search Employee By its Id
  • Display Name in sorted order
  • Display Id in sorted order
  • Display All record

Manage Data(Updation)

This option will give the feature to update the name and salary of a particular employee all you have to do is to provide the employee id that you looking for updation.



I hope that It help you understand the basic concept of calling function and all other stuff.


Advice

its my advice to run this program in cmd it you don't know how deal java programming with command prompt then read read the following page carefully

[Question 3] ISC 2017 Computer Practical Paper Solved – Caesar Cipher.

Image
Question 3: Caesar Cipher  is an encryption technique which is implemented as ROT13 (‘rotate by 13 places’). It is a simple letter substitution cipher that replaces a letter with the letter 13 places after it in the alphabets, with the other characters remaining unchanged. Write a program to accept a plain text of length L, where L must be greater than 3 and less than 100. Encrypt the text if valid as per the Caesar Cipher. Test your program with the sample data and some random data: Example 1 INPUT :  Hello! How are you? OUTPUT :  The cipher text is: Uryyb? Ubj ner lbh? Example 2 INPUT :  Encryption helps to secure data. OUTPUT :  The cipher text is: Rapelcgvba urycf gb frpher qngn. Example 3 INPUT :  You OUTPUT :  INVALID LENGTH SOURCE CODE    import java.io.*; import java.util.*; public class ISC2017_CaesarCipher {     public static void main(String args[])     {         Scanner sc=new Scanner(System.in);         System.out.pri

Pattern program of your own name. This is a pattern program, in this program you just have to enter your name and it will give you output in a particular manner. I have created this program when I was in class 10th for my Computer Application project. NOTE:  If you are copying my code then its a advise to you to copy it after downloading it to avoid any kind of compilation error its link is available at the bottom of source code. SOURCE CODE import java.io.*; public class Patter_of_your_Own_Name { public static void main(String args[])throws IOException { int time=1; BufferedReader br=new BufferedReader(new InputStreamReader(System.in)); do { System.out.print("\n\t\t\tPLEASE,ENTER YOUR GOOD NAME IN CAPITAL LETTER           :"); String str=br.readLine(); int flag=0;
