How can I store an array of objects in an arraylist?
I'm creating a simple RPG game using Java. I have a class called "Character" with three attributes - name, level, and health. I have created an arraylist to store them all in.
I'm trying to store all of the characters in my arraylist so that I can iterate through them to create a print-screen of the game. My current code is:
public ArrayList characters = new ArrayList();
public void create(){
Character John = new Character("John", 1, 5);
characters.add(John);
}
public void createCharacter(){
for (Character character : characters){
System.out.println(character.getName() + " (" + character.getLevel() + ") has " + character.getHealth() + " health!");
}
}
But my print-screen prints out:
John (1) has 5 health!
I'm trying to understand why it is printing out the health instead of the character. Could someone explain it to me?
A:
In the line
System.out.println(character.getName() + " (" + character.getLevel() + ") has " + character.getHealth() + " health!");
you are actually using the toString() method of the Character class. If you wanted to print a String that represents the object, you would have to call toString() on the object to do that. If you want to display the class of the object, you would be359ba680
