Question

Suppose you start with

                         // Set<String>
Object arrayOfSomething[] = someObject.toArray();

Now, i know that arrayOfSomething is really an arrayOfStrings, i’d like to iterate over

Currently, i

for (Object o : arrayOfSomething) {
   String strValue = ((String) o).trim();
    ...

Is something along the following possible:

for (String (String) strValue : arrayOfSomething) {
    ...

Is it possible to cast an object as part of a fast enumeration?

Answer 1

There is also a method Collection.toArray(T[]) returning an array of type T instead of an array of Objects.
