the actual question is: Develop a client/server application that calculates the pay for employees. Some employees are permanent and others are casual.
Permanent employees have a set annual salary and are eligible for sick leave and annual leave.
Casual employees are paid an hourly rate for the actual hours they worked.
Employees are paid fortnightly.
Client side of the application is to gather information about the employee and send it to the server that will calculate the gross pay, tax paid and net pay.
This information will be sent back to the client to be displayed.
Client side interface GUI that allows the user to choose between permanent or casual. If permanent then the user is asked to enter the employee’s name, id number, annual salary and have drop down list for leave taken that defaults to none but annual or sick can be chosen. If either is chosen then the user will be asked how many days.
If casual then the employee’s name, id number, pay rate and hours worked are entered. The formula to calculate tax is the same for both categories of employees. These figures are per fortnight.
First $700 is tax free anything earned over $700 up to $1500 is taxed at 19c per dollar and any amount over $1500 is taxed 38c per dollar. Application is to include data validation. This should be done before the data is sent to the server. All number entries should be greater than 0 and hours worked for casuals must be five or more and less than 72. A message should be shown to the user and the user should be then able to re-enter the data.
I did the best i could, does anyone or can anyone make this real simple as I have spent hours and hours and hours and more hours and it has issues:
