1.1 added some new constructors.  I'll leave it to you to decide which you like:

  public String(byte[] bytes, int offset, int length, String enc) throws
UnsupportedEncodingException;
  public String(byte[] bytes, String enc) throws UnsupportedEncodingException;
  public String(byte[] bytes, int offset, int length);
  public String(byte[] bytes);


As for creation of a new object and a cast, you might find it faster to declare
a
object prior to the while.. statement, and clone it inside.  I recall seeing an
article
on JavaSoft's web site that indicated casting and object creation are
bottlenecks
in terms of cpu cycles currently.
