Passing ArrayList?

[0c0de]

Hi fairly new at programming and I'm trying to build my first actual program. I've created an ArrayList in one class and created a method in another class so I can display it on my main class.

import java.util.*;

class PokeMonAbilities {

	private ArrayList<String> ability; 

	public PokeMonAbilities(){
		
		ability = new ArrayList<String>();
		ability.add("d");

	}

	
	 public ArrayList<String> getAbility(){
		return ability;
	}		
}

And here's my main class

public static void main(String[] args){
		
...
System.out.println("Bulbasaur ability is: " + bulbasaur.getAbility());
	}

I'm really trying to get my programming skills up any help or suggestions would be great.

Printing an arraylist probably won't give you its contents; try to iterate it with a foreach instead:

PHP Code:

for (String sAbility : bulbasaur.getAbility())
{
    System.out.println("Bulbasaur ability is " + sAbility);
} 


You don't show how you are getting the bulbasaur though, and you don't mention what the problem is, so I have to assume its nothing to do with either a compile time error, or a runtime error and only the output.

Inorder to print the contents of ArrayList your need to iterate over it.

for(Iterator i = arrayList.iterator();i.hasNext()
{
System.out.println(i.next());
}

with java 1.5 onwards you can use for each loop to iterate through arrayLists

Thanks will try it out.

The solution provided by Fou-Lu is better since it uses the iteration of JDK 1.5 that is more performant than the old Iterator thing.

So I still get some compile errors, I wanna make it clear what I'm trying to get accomplished with this program. So I would to make say class B initialize arrayList's with some index's, and class A my main class to print out the index from class B. Thanks for quick responses.

Can you post what you are using? You have a public method in there to access the underlying ArrayList object, so that shouldn't be a problem at all.
