My java program takes in employees and their weekly hours and outputs their total hours. What I can not figure out how to do is to sort the emplyees in descending order from the ammount of hours they worked a week. My program currently sorts them in the order they were entered by the user. Can you walk me through the steps I need to take to sort them by hours worked? Below is my program.

import java.util.Scanner;

public class EmployeeWorkHours {

public static void main(String[] args) {

int numberOfEmployees=0;

int workDays=0;

Scanner in = new Scanner(System.in);

//asks for number of employees

System.out.println("Please enter the number of employees");

boolean employeeNumberflag = true;

while (employeeNumberflag) {

try {

numberOfEmployees = Integer.valueOf(in.nextLine());

if (numberOfEmployees <= 0)

System.out.println("Please enter an positive integer.");

else

employeeNumberflag = false;

}

catch (NumberFormatException e) {

System.out.println("Please enter an positive integer.");

}

}

//asks length of work week from 1-7

System.out.println("Please enter the number of work days in a week. Accepable values are 1-7.");

boolean daysFlag = true;

while (daysFlag) {

try {

workDays = Integer.valueOf(in.nextLine());

if (workDays > 0 && workDays < 8) {

daysFlag=false;

}

else {

daysFlag = true;

System.out.println("Please enter an integer from 1-7.");

}

}

catch (NumberFormatException e) {

System.out.println("Please enter an integer from 1-7.");

}

}

//creating empty arrays for employee names and hours

String[] employees = new String[numberOfEmployees];

int[][] hoursWorked = new int[numberOfEmployees][workDays];

//outer loop takes employee names and inputs them into employee[]

for (int i=1; i

System.out.println("Please enter the name of employee " + i + ".");

employees[i-1] = in.nextLine();

//inner loop takes number of hours each day worked for each employee

System.out.println("Please enter " + workDays + " work day hours.");

for (int j=1; j

System.out.println("Please enter an integer from 0-24 for work day " + j +".");

boolean hoursFlag = true;

while (hoursFlag) {

try {

int hours = Integer.valueOf(in.nextLine());

if (hours > -1 && hours < 25) {

hoursWorked[i-1][j-1] = hours;

hoursFlag = false;

}

else {

hoursFlag = true;

System.out.println("Please enter an integer from 0-24.");

}

}

catch (NumberFormatException e) {

System.out.println("Please enter an integer from 0-24.");

}

}

}

}

//print out desired output table for employees and hours

for (int h=0; h

System.out.printf("%-15s%14d ",employees[h], calculateHours(hoursWorked[h]));

}

}

//method that takes each employee hours and adds them all up

public static int calculateHours(int[] hours) {

int total = 0;

for (int i=0; i

total += hours[i];

}

return total;

}

}
