Re: Directly Modify Vector Item

Is it possible to directly manipulate an item within a Vector (or any
other AbstractCollection).

Basically, I retrieve and manipulate vectors in the following way:

Vector myVec = new Vector();
// populate...

for (int i = 0; i < myVec.size; i++) {
  String myStr = (String)myVec.get(i);
  myStr = "String " + i;
  myVec.setElementAt(myStr, i);

}

While arrays can simply modify directly:

for (int i = 0; i < myVec.size; i++) {
  myArray[i] = "String " + i;

}

The first method seems cumbersome and inefficient, especially when
using a class other than a String (one with many modifications to be
made).

I'm fairly new to Java, so I'm sure I've been going about this the
wrong way. I would very much appreciate some enlightenment.
