java hashmap key iteration

Question

Is there any way to iterate through a java Hashmap and print out all the values for every key that is a part of the Hashmap?

Answer 1

for (Map.Entry e : map.entrySet())
{
    T key = e.getKey();
    U value = e.getValue();
    .
    .
    .
}

In addition, if you use a LinkedHashMap as the implementation, you'll iterate in the order the key/value pairs were inserted. If that's not important, use a HashMap.
