Arrays and Collections

Arrays are of fixed size and lack methods to manipulate them

Vector is the most widely used class to hold a collection of other objects

• More powerful than arrays, but less efficient

Iterators are used to access members of Vectors

• Enumerations were formally used, but were more complex

  v = new Vector();
  
  
  Iterator i = v.iterator();
  while(i.hasNext())
  {
  aMethod(v.next());
  }
