In this programming question, you have the following classes: Hero.java and HeroTester.java.

Hero.java is as follows:

package question2; import java.util.ArrayList; import java.util.Scanner; public class Hero { private String name; private int health; private int max_items; private ArrayList items; /** * Constructor used to set values. * * @param name for the hero's name. * @param max_items for the maximum number of items that the hero can carry. */ public Hero (String name, int max_items) { // set the hero's name to provided name this.name = name; try { // If the max_items is less than zero or more than 10, throw IllegalArgumentException if(max_items < 0 || max_items > 10) throw new IllegalArgumentException("The maximum number of items that you can carry is from 1 to 10"); // set the max_items to the the second argument provided. this.max_items = max_items; } catch(IllegalArgumentException e) { System.out.println("You cannot carry that many items! " + e.getMessage()); } // set hero's health to 100 this.health = 100; // initialize the items list as empty this.items = new ArrayList<>(); } /** * Default constructor */ public Hero () { // set the hero's name to "Anonymous" this.name = "Anonymous"; // set the max_items to 2 this.max_items = 2; // set hero's health to 100 this.health = 100; // initialize the items list as empty this.items = new ArrayList<>(); } /** * Inventory method which stores the items the hero's items. * * @return a string using the .toString method */ public String inventory() { String sb = ""; // If the hero is not carrying anything, print a suitable message if (items.size() == 0) { sb += ("Your hero is unburdened by wordly possessions."); } // prints the list of items carried by hero else { sb += ("Displaying Inventory : "); sb += ("["); // Loop1: To print all the items for (int i = 0; i < items.size(); i++) { sb += (items.get(i) + ", "); } sb += (" ]"); } return sb.toString(); } /** * Take method for adding items to hero's inventory/. * * @param item is used for the hero to take/ carry an item */ public void take(String item) { System.out.println("Handling Sir " + getName() + " " + item); // If the inventory is full, print an appropriate message if(items.size() == max_items) { System.out.println("Your hero is overburdened and cannot carry more..."); } else { //add the item to the inventory items.add(item); } } /** * Drop method used for hero to drop items from the hero's inventory * * @param item which the hero may/may not drop. Depends on either hard-coded hero * or the final user input. */ public void drop(String item) { // If the hero is not carrying the item, print an appropriate message if(!items.contains(item)) { System.out.println("Your hero is not carrying that item - " + item); } else { //drop the item from the inventory System.out.println("Brave sir " + getName() + " drops his " + item); items.remove(item); } } /** * Take damage method for the hero to take damage and lose health * * @param amount is used to keep track of how much damage the hero can take. */ public void takeDamage(int amount) { health -= amount; //if hero's health is less than 0, make it 0 if(health < 0) { health = 0; System.out.println("Remember, a hero can't have negative health nor health > 100"); } } /** * Heal method is used to heal the hero * * @param amount is used to heal the hero. */ public void heal(int amount) { health += amount; //if hero's health is more than 100, make it 100 if(health > 100) { health = 100; System.out.println("Remember, a hero can't have negative health nor health > 100"); } } @Override /** * toString method used for printing necessary information. */ public String toString() { return "Displaying hero: Hero: Brave Sir " +this.name+ ", "+ "health: " + this.health + ", " + "can carry: " + this.max_items+ ", " + "current inventory: " + inventory(); } /** * getName method to get the hero's name. * * @return hero's name */ public String getName() { return this.name; } /** * setName method to set the hero's name. * * @param name is hero's name. */ public void setName(String name) { this.name = name; } }

HeroTester is as follows:

package question2; import java.util.Scanner; public class HeroTester { public static void main(String[] args) { //Option 1 will decide if user chooses hard coded heroes // or to create a user inputted hero int opt1; Scanner sc = new Scanner(System.in); do { System.out.print("1.

");} }while(opt2!=1 && opt2 != 2); System.out.println(" ");

if(opt2 == 1) { System.out.println("Creating Hero with no name."); //create a new hero using default constructor hero = new Hero(); //print hero state System.out.println(hero.toString()); } else { System.out.println("Creating Hero with a name."); System.out.print("Enter hero's name: "); String name = sc.next();

System.out.print(" Enter max items that the hero can carry: "); int max = sc.nextInt(); //create a new hero using argumented constructor hero = new Hero(name, max);

System.out.print(" Enter your choice: "); int opt3; opt3 = sc.nextInt();

System.out.println(" "); switch(opt3) { case 1: //add item to hero's inventory System.out.print("Enter item's name to be added: "); String take = sc.next(); hero.take(take); System.out.println(hero.toString()); break; case 2: //drop item from hero's inventory System.out.print("Enter item's name to be dropped: "); String drop = sc.next(); hero.drop(drop); System.out.println(hero.toString()); break; case 3: //Cause damage to the hero System.out.print("Enter the health damage amount: "); int damage = sc.nextInt(); hero.takeDamage(damage); System.out.println(hero.toString()); break; case 4: //Heal the hero System.out.print("Enter the healing amount: "); int heal = sc.nextInt(); hero.heal(heal); System.out.println(hero.toString()); break; case 5: //Display the hero's state System.out.println(hero.toString()); break; case 6: System.out.println("Exiting!!"); return; default: //In case user enters an invalid option. System.out.println(" Enter a valid option!!"); } } }

} }

Using the following classes, find a way to load and save to a file instead of forcing the user to create a new character every time. Using the following is not allowed:

- String Builder

- Buffered Readers

- Apache commons or any others of the type.

Remeber, the key here is to allow the user to load a character from a file in your desktop (or a location of your preference) and use it to run through the code. Then allow the user to save the progress on the same file, again. Good luck!
