public boolean containsAll(Collection c)
This method takes a Collection as its argument, (not necessarily) a Vector, and reports
if the elements of the collection are a subset of the vector's elements.
import java.util.Vector;

public static void main(String args[]) {
Vector v = new Vector();
v.add("A");
v.add("B");
Vector v2 = new Vector();
v2.add("A");
v2.add("B");
v2.add("C");
boolean isContaining = v2.containsAll(v);
System.out.println(isContaining);
