Question

Create a program to compute a worker's daily salary in java.

      input: hour_rate, number_of_hours

   output: salary = hour_rate * number_of_hours

Modify the program to compute a worker's daily salary based on the following table:

   --------------------------------------

   | $7.00/hr | The first 8 hours |

   --------------------------------------

   | $9.00 /hr | After 8 hours |

   --------------------------------------

   For example, if a worker works 10 hours, then her/his salary is

       $7.00/hr * 8 hrs + $9.00/hr * (10 - 8) hrs

   Note: The number 7.00 is read from keyboard. 9.00 is fixed.

   Modify the program to compute N worker's daily salary.

   The number N is an input to this program.

Explanation / Answer

/**The java program that prompts the number of workers
* and asks to enter number of hours and pay rate of the worker
* then calculate the salary for each employee for N workers
* and display the salary as per the given pay rates in the program and display the total salary paid to workers.
