Question

In JAVA, In two classes:

As a zookeeper, it is important to know the activities of the animals in your care and to monitor their living habitats. Create a monitoring system that does all of the following:

-Asks a user if they want to monitor an animal, monitor a habitat, or exit

-Displays a list of animal/habitat options (based on the previous selection) as read from either the animals or habitats file and asks the user to enter one of the options

-Displays the monitoring information by finding the appropriate section in the file

-Separates sections by the category and selection (such as “Animal - Lion” or “Habitat - Penguin”)

-Uses a dialog box to alert the zookeeper if the monitor detects something out of the normal range (These will be denoted in the files by a new line starting with *****. Do not display the asterisks in the dialog.)

-Allows a user to return to the original options

The class that I need assistance in creating is the "Monitoring" class that is menu driven and will create an "AnimalsHabitat" object and call the methods in it.

The AnimalsHabitat file has already been created. The txt files are below.

AnimalsHabitat:

String textLine = null;

ArrayList aList1 = new ArrayList();

int i = 0;

int option = 0;

boolean bailOut = false;

// open file

fileByteStream = new FileInputStream(filePath + fileName + ".txt");

inFS = new Scanner(fileByteStream);

while (inFS.hasNextLine() && bailOut == false) {

textLine = inFS.nextLine();

if (textLine.contains("Details")) {

aList1.add(str);

}

else {

System.out.println("");

if (option <= i) {

String detailOption = aList1.remove(option - 1).toString();

showData(fileName, detailOption);

bailOut = true;

} break;

}

}

// close file
