Basic treemap loop

So I want to make a for loop for a tree map to get the highest number right now I have:

Code :

---

public void findRichestInList()
    {
        bank = new TreeMap<String, Integer>();
        bank.put("Dave",139);
        bank.put("Mary",99);
        for(.......
}

---

I am not sure how to write the loop to check each record.
How would I do this?
Also would it be easier to use a hashMap instead of a treemap?

A HashMap won't preserve order.

A TreeMap preserves the order of its keys, in this case the String names. So using TreeMap doesn't really get you anything either, if you're trying to get the order of the numbers.

You can get a Set containing all of the keys of the Map by calling keySet(). Then you can use that to loop over all of the values, searching for the largest one.

Well with the example I am doing I have to do it with either a treemap or a hashmap. I just need to know what I would put inside the brackets for a for loop so it will check through each record.

Iterate over the key Set. See The Map Interface (The Java™ Tutorials > Collections > Interfaces) for some examples.
