Simple HashMap question

[jvanhalderen]

Hello, Im using a hashmap to map a counter to certain names. What i want now it print all tag names with assigned values, yet this code print the right value but not the tagname itself but the pointer to the name.

Code (simplified):

HashMap hm = new HashMap();

hm.add ("A", new Integer(1));
hm.add ("B", new Integer(2));
hm.add ("C", new Integer(3));

Set set = hm.keySet();
Iterator iter = set.iterator();
while (iter.hasNext()){
temp1 = hm.get(iter.next()).toString();
temp2 = iter.getValue().toString();
System.out.println(temp1 + " = " + temp2);
}

Wanted output:

A = 1
B = 2
C = 3

Any help would be appreciated!

I see what you are trying to do, but you're using methods that don't even exist

what you want can be accomplished in many ways, this is the most straight forward...

HashMap hm = new HashMap();

hm.add ("A", new Integer(1));
hm.add ("B", new Integer(2));
hm.add ("C", new Integer(3));

Set set = hm.entrySet();

Iterator iter = set.iterator();

while(iter.hasNext()) {
Map.Entry me = (Map.Entry)iter.next();

System.out.println(me.getKey() + " = " + me.getValue());

}
