Iterator, with ArrayList

I get compile error when trying to use method of something i got off iterator.next()

first off, I have a class named word, it has a method called getWord which returns a String.

Code :

---

import //all needed packages
public class unique
{
 
ArrayList<word> words = new ArrayList<word>();
 
public unique(.........)
{
//filling ArrayList with objects of type word.
}
 
private boolean checkForWord(String token)
{
 
Iterator itr = words.iterator();
String temp;
 
while(itr.hasNext())
    {
        temp = itr.next().getWord();
        [COLOR="Red"]//COMPILE ERROR ON THE LINE ABOVE[/COLOR]:-q:-q:-q
        if(temp.equals(token))
        return true;
    }
 
    return false;
}

---

Code :

---

public class word
{
String token;
 
public word (String token)
{
    this.token = token;
}
public String getWord()
{
    return token;
}
 
}

---

The compile error I receive is , cannot find method getWord()

Any ideas?

I suspect it may have something to do with iterator POSSIBLY returning type OBJECT ..but even if this is the case, how do I convert this back to a "usable" object of type word?

Add a cast.

Code :

---

temp = ((word)itr.next()).getWord();

---

You might get a warning that says this is a potentially unsafe cast, but since you know that the iterator can only return a word, you can ignore the warning.

xD

I found a solution a little while ago :O

by setting the type of the iterator, didnt know i could do it.

Code :

---

Iterator<word> itr = words.iterator();

---

thanks though

You can also use a special for loop syntax that automatically handles iterators.

Code :

---

for (word w : words) {
    System.out.println(w.getWord());
}
