Sorting a HashTable

[Frank E Robinson]

Hello All,
Would you give me some insight on how to sort values in a has table. I just started teaching myself Java. Below is my code that creates a has with some values. If you could point me to some good references that would be great also.
thanks in advance
import java.util.*;
public class hs
{
static HashSet myHS = new HashSet();

public static void main(String[] arg)
{

createHS();
showHS();
}
public static void createHS()
{
String s1="B", s2="E", s3="U", s4="A", s5="Z", s6="T";
myHS.add(s1);
myHS.add(s2);
myHS.add(s3);
myHS.add(s4);
myHS.add(s5);
myHS.add(s6);
}

public static void showHS()
{
Iterator i = myHS.iterator();
while( i.hasNext() )
{
System.out.println(" tool: " + i.next() );
}
}
}

You really can't sort the entries in a Hashtable, HashMap or HashSet. They're not stored in sorted order when you put them into the map, and you can't reorder them later. If you want to sort something, and you want to simultaneously maintain a Map relationship between keys and values, then you want to use a SortedMap - an interface which has one standard implementation, TreeMap. That's the class you want.

Thanks Jim, I'll look into SortedMap.
