Thread: Re: Resetting Accumulator after first itterneration

Is there any way in Java to reset my accumulator to zero after I get all of my user data in my first go around in my loop and have it displayed. Here is a short posting of my code. After my first nursing home I want my accumulator to be zero for my next nursing home data. My accumulators are collecting all user data for my total rooms and total occupied rooms when I want it split up between nursing homes.

<public class project3DemoMorris
{

public static void main(String[] args)
{
int buildNum; //number of buildings
int floorNum; //number of floors
int roomFloor; //number of rooms per floor
int occupiedRooms; //number of occupied rooms
int floorsCount;
int totalRooms;
int totaloccupiedRooms;

//Display the heading of our program
displayMessage();

//Create a Scanner object for keyboard input.
Scanner keyboard = new Scanner(System.in);
DecimalFormat formatter = new DecimalFormat ("#0%");

totalRooms=0;
totaloccupiedRooms=0;



//Get the number of buildings
System.out.println("Enter the number of buildings");
buildNum = keyboard.nextInt();





while (buildNum<=0)
{

System.out.println("Invalid entry: Number of buildings must be greater than 0.");
System.out.print("Reenter the number of buildings:");
buildNum = keyboard.nextInt();
}

for (int buildingCount = 1; buildingCount <= buildNum; buildingCount++)
{
System.out.print("How many floors are in the nursing home " + buildingCount +"?: ");
floorNum = keyboard.nextInt();


while (floorNum<=0)
{
System.out.println("Invalid entry: Floors must be greater than 0.");
System.out.print("Reenter the number of floors in nursing home " + buildingCount +":");
floorNum = keyboard.nextInt();
}
for (floorsCount = 1; floorsCount<=floorNum; floorsCount++)
{

System.out.print("How many rooms does floor" + floorsCount+"?: ");
roomFloor = keyboard.nextInt();


while (roomFloor<10)
{
System.out.println("Invalid entry: Rooms cannot be less than 10.");
System.out.print("Reenter the number of Rooms.");
roomFloor = keyboard.nextInt();
}


totalRooms+=roomFloor;

System.out.print("How many occupied rooms are on the floor?: ");
occupiedRooms = keyboard.nextInt();


while (occupiedRooms<=0)
{
System.out.println("Invalid entry: Occupied rooms must be 0 or greater.");
System.out.println("Reenter number of occupied rooms on the floor.");
occupiedRooms = keyboard.nextInt();
}


totaloccupiedRooms+=occupiedRooms;

// System.out.println(totaloccupiedRooms);
//System.out.println(totalRooms);


//Create an instance of project3Morris
//passing the data that was entered as arguments

I'm not sure what you mean by accumulator, but why can't you just reset all class fields to zero or as would be appropriate for each data type? Or, you can start with a fresh object with all values set to their defaults by simply reinitializing an existing object:

myObject = new MyObject();

I want nursing home 1 total rooms or total occupied rooms separate from nursing home 2. instead of saying 80 total rooms it should say 60. it should say 20 for the first nursing home.


This is the Sunshine Nursing Home Program:
Enter the number of buildings
2
How many floors are in the nursing home 1?: 1
How many rooms does floor1?: 20
How many occupied rooms are on the floor?: 15
Nursing Home:2
Total Number Of Rooms:20
Total Occupied Rooms:15
Total Vacant Rooms:5
Occupancy Rate:75%
Occupancy Rate is High
How many floors are in the nursing home 2?: 3
How many rooms does floor1?: 20
How many occupied rooms are on the floor?: 8
Nursing Home:2
Total Number Of Rooms:40
Total Occupied Rooms:23
Total Vacant Rooms:17
Occupancy Rate:40%
Occupancy Rate is Low
How many rooms does floor2?: 20
How many occupied rooms are on the floor?: 5
Nursing Home:2
Total Number Of Rooms:60
Total Occupied Rooms:28
Total Vacant Rooms:32
Occupancy Rate:25%
Occupancy Rate is Low
How many rooms does floor3?: 20
How many occupied rooms are on the floor?: 11
Nursing Home:2
Total Number Of Rooms:80
Total Occupied Rooms:39
Total Vacant Rooms:41
Occupancy Rate:55%
Occupancy Rate is Average

resetting classes way over my head this is a beginner java class. were just learning to create classes.
