TASK #1In the domain class you will create a loop that will prompt.pdf

TASK #1
In the domain class you will create a loop that will prompt the user to enter a value of 1, 2, or 3,
which will in turn, be translated to a floor number in the game. Make sure the user only picks a
selection you are expecting (1, 2, or 3) with a while-loop. Then you will create a switch or if-else
statement. If you are more comfortable with if-else then do switch, or if you are more
comfortable with switch then do if-else. Based on the number the user chooses you will set the
floor variable to the appropriate value. When they select 1 floor should be set to 3, when they
select 2 floor should be set to 6, and when they select 3 floor should be set to 10.
TASK #2
In the domain class you will create a constructor with 6 parameters, representing all the data
loaded from the input file that was saved from a previous adventure. This constructor receives 6
parameters: aName, anAttack, aDefense, aHealth, aCurrentFloor, & aMaxFloor.
TASK #3
In the domain class you will create a save method that will allow the user to save their progress
using a PrintWriter object. This file will overwrite whatever was there before, so no need to use
FileWriter, only PrintWriter. There are 6 attributes that you need to write to the file:
name, attack, defense, health, currentFloor, & maxFloor
public void saveFile()
{
String filename = “game.txt”;
PrintWriter pw = new PrintWriter(filename);
pw.println(name);
pw.println(attack);
pw.println(defense);
pw.println(health);
pw.println(currentFloor);
pw.println(maxFloor);
pw.close();
}
TASK #4
In the driver class you will create a load method that will allow the user to pick up from where
they left off. You will do this using a File object and a Scanner object. Remember to use the File
and Scanner classes, and to close the file object after you’re done. There are 6 attributes you will
need to load from the file to successfully continue an Adventure:
name, attack, defense, health, currentFloor, & maxFloor

After you read the record from the file, and store the data in these 6 variables, you can create a
new Adventure object called JavaQuest with those 6 variables. Remember JavaQuest is a global
variable defined at the beginning of the driver class. Then, within the load method, invoke the
startAdventure() method for the newly created Adventure object.
public static void load()
{
String filename = “load.txt”;
File myFile = new File(filename);
Scanner myScan = new Scanner(myFile);
String name;
int attack, defense, health, currentFloor, maxFloor;

attack = myScan.nextInt();
myScan.nextLine();
defense = myScan.nextInt();
myScan.nextLine();
…
javaQuest = new Adventure(name, attack, defense, health, currentFloor, maxFloor);
}
javaQuest.startAdventure();
