Java Project Name: IC17_HackerChallenge

Extend IC17_iSleepy to include a prompt to ask the user's age. Based on the user input (for sleep hours) and the user's age group, report the appropriate sleep health category.

Write a Java console program that will monitor how much sleep you obtained each night last week and store the data (number of hours) into an array. After all 7 days have been entered, be sure to display the total number of hours slept in the week, the average number of hours slept last week, how many nights were of "Recommended" sleep, how many "May be Appropriate" and how many were "Not Appropriate". Then, based on average number of hours slept per night, determine the person's overall sleep health category (e.g. "Recommended", "May be Appropriate" or "Not Recommended"). ***Note: for regular credit - make the sleep health category determination based on your age group*** The Hacker Challenge will include a prompt for age.

Here is an example transaction with a user (for the Young Adults age group):

THIS IS MY CODE SO FAR. I JUST NEED TO ADD THE USERS AGE INPUT AND IT WILL BE SET. RIGHT now I just have the young age group.

import java.text.DecimalFormat;

import java.util.Scanner;

public class iSleepy {

// Declare a constant for the size

public static final int SIZE = 7;

public static void main(String[] args) {

Scanner consoleScanner = new Scanner(System.in);

DecimalFormat twoDPs = new DecimalFormat("0.00");

// Declare the arrays for hours slept

double[] hoursSlept = new double [SIZE];

//Declare the days in a week(pre-known)

String[] days = {"Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"};

//Declare the sum and average

double sum = 0.0, average;

int rec = 0, app = 0, notRec= 0;

//Let's loop through the array (allow user to enter values)

for (int i = 0; i

{

System.out.print("Enter number of hours slept on "+days[i]+" : ");

hoursSlept[i] = consoleScanner.nextDouble();

// Add the hours to the sum

sum += hoursSlept[i];

//Determine whether recommended, appropriate or not recommended

if(hoursSlept[i]>=7 && hoursSlept[i]

{

rec++;

}

else if(hoursSlept[i] 11)

notRec++;

else app++;

}

consoleScanner.close();

average = sum/hoursSlept.length;

System.out.println(" Total number of hours slept last week : "+twoDPs.format(sum)

+" Average Number of hours slept per night : "+twoDPs.format(average));

System.out.println(" According to the NSF, last week, you slept: "

+ rec+(rec==1?" Night":" Nights") +" of \"recommended\" sleep. "

+app+(app==1?" Night":" Nights")+" of \"appropriate\"sleep. "

+notRec+(notRec==1?" Night":" Nights")+" of \"not recommended\" sleep. ");

if (average>=6 && average

System.out.println("Overall, your sleep health (on average) is \"Recommended\"");

else if (average >=10 && average

{

System.out.println("Overall, your sleep health (on average) is \"May be appropriate\"");

}

else

System.out.println("Overall, your sleep health (on average is \"Not recommended\"");

}

}
