you can not initialize a collection. you need to use a vector, hashset,
arraylist, linkedlist or any of its implementation (please refer to
javadoc). but if you really need a collection, just type cast any instance
of a collection implementation class to a collection variable.
consider the ff:
class VectorToCollection{
public static void main (String args[]) {
//create an instance of a vector class
java.util.Vector v = new java.util.Vector();
//populate the vector
v.add("one");
v.add("two");
v.add("three");
//assign the values of the vector to a collection by type casting
java.util.Collection c = (java.util.Collection) v;
java.util.Iterator i = c.iterator();
while(i.hasNext()){
System.out.println(i.next());
}
}
}
