Given:
Enumeration enum;
Do this:
while (enum.hasMoreElements()) {
Object obj = enum.nextElement();
// do something with obj here
}
Since enumerations generally contain things other than just plain
Objects, you will typically need to use a cast. For example, let's
assume that your enumeration contains Frame objects; then the first
line inside the WHILE loop would look like this:
Frame f = (Frame) enum.nextElement();
