Answer to Question #255422 in Java | JSP | JSF for KK.Da

Question

Using a while loop create a program that calculates the monthly salary of  N employees[where N is the number of employees that's entered by the user]. If the employee worked less or equal to 160 hours, the employee will be paid N$240.00 per hour. For any hours greater than 160, the employee is paid N$320.00 per hour.

Sample Run1      

Enter number of employees(N):3                         

Hours worked 1: 160                                               

Hours worked 2: 200                                                           

Hours worked 3: 80 

Output1:                                                     

Salary 1: N$38400.00

Salary 2: N$51200.00                                                        

Salary 3: N$19200.00                      

Sample Run 2

Enter number of employees(N):0 

Output2: 

No employees provided to do calculations

Sample Run 3

Enter number of employees(N):-4 

Output 3:

Number of employees cannot be negative

import java.util.Scanner;

		if (N > 0) {
			int hoursWorked[] = new int[N];
			int i = 0;
			while (i < N) {
				System.out.print("Hours worked " + (i + 1) + ": ");
				hoursWorked[i] = keyBoard.nextInt();
				i++;
			}
			i = 0;
			while (i < N) {
				// If the employee worked less or equal to 160 hours, the employee will be paid
				// N$240.00 per hour.
				double salary =0;
				// For any hours greater than 160, the employee is paid N$320.00 per hour.
				if (hoursWorked[i] <= 160) {
					salary =hoursWorked[i] * 240.0;
				}else {
					salary =160 * 240.0+(hoursWorked[i]-160)*320.0;
				}
				System.out.printf("Salary %d: N$%.2f\n", (i + 1), salary);
				i++;
			}
		} else if (N == 0) {
			System.out.println("No employees provided to do calculations");
		} else {
			System.out.println("Number of employees cannot be negative");
