Okay:

[code=java]public static Number[][] min2max2(Number[] numbers) {

  if (numbers.length < 2)

    throw new IllegalArgumentException();

  Number[] sorted = numbers.clone();

  java.util.Arrays.sort(sorted);

  return new Number[][] {

    { sorted[0], sorted[1] },

    { sorted[numbers.length - 2], sorted[numbers.length - 1] }

  };

}[/code]
