Re: Using Arrays and Collections

  In the meantime, this has been answered by others.

  So, here is my next attempt:

public static int max
( final int[] a )
{ int result = 0;
  if( a.length == 0 )
  throw new java.util.NoSuchElementException
  ( "The argument value was an empty array, " +
    "but I can't compute the maximum of an empty array." );
  else
  { result = a[ 0 ];
    for( int i : a )if( i > result )result = i; }
  return result; }

  The exception-behavior is now the same as that of

http://download.java.net/jdk7/docs/api/java/util/Collections.html#max(java.util.Collection)

  , which also throws

http://download.java.net/jdk7/docs/api/java/util/NoSuchElementException.html

  if there is no element.

  The loop now iterates over all components of the array, but
  the body stil only does one test per iteration.

  By this, finding the optimum implementation of loop details
  now was left to the compiler.
