    DoubleBinding s = a.add(b).divide(2.0D);

    final DoubleBinding aBinding = new When(a.add(b).greaterThan(b).and(a.add(a).greaterThan(b)))
            .then(s.multiply(s.subtract(a)).multiply(s.subtract(b))).otherwise(0.0D);

    a.set(3);
    b.set(4);//from w  w w. j  a v a 2 s.  c om
    System.out.println(a.get());
    System.out.println(b.get());
