The following table containing information about employees of an organization, develop a small java application, which accepts employee id from the command prompt and displays
the following details as output:
Emp No Emp Name Department Designation and Salary
You may assume that the array is initialized with the following details:
| Emp No. | Emp Name | Join Date | Desig Code | Dept | Basic | HRA | IT |
| 1001 | Ashish | 01/04/2009 | e | R&D | 20000 | 8000 | 3000 |
| 1002 | Sushma | 23/08/2012 | c | PM | 30000 | 12000 | 9000 |
| 1003 | Rahul | 12/11/2008 | k | Acct | 10000 | 8000 | 1000 |
| 1004 | Chahat | 29/01/2013 | r | Front Desk | 12000 | 6000 | 2000 |
| 1005 | Ranjan | 16/07/2005 | m | Engg | 50000 | 20000 | 20000 |
| 1006 | Suman | 1/1/2000 | e | Manu factur ing | 23000 | 9000 | 4400 |
| 1007 | Tanmay | 12/06/2006 | c | PM | 29000 | 12000 | 10000 |
Salary is calculated as Basic+HRA+DA-IT. (DA details are given in the Designation table)
Designation details :
| Designation Code | Designation | DA |
| e | Engineer | 20000 |
| c | Consultant | 32000 |
| k | Clerk | 12000 |
| r | Receptionist | 15000 |
| m | Manager | 40000 |
Use Switch-Case to print Designation in the output and to find the value of DA for a particular
employee.
O/P Expected:
1. Assuming that your class name is Hello, and you execute your code asjava Hello 1003, it should display the following output :
Emp No. Emp Name Department Designation Salary
1003 Rahul Acct Clerk 29000
2. java Hello 123
There is no employee with empid : 123
Solution:
public class Hello {
public static String Designation;
public static int DA;
public static void main(String args[]) {
if(args.length==0)
System.out.println("Please Provide Emp No.");
else {
int EmpNo =Integer.parseInt(args[0]);
