beauty of lambda

foreEach in the library takes a Consumer Interface implementation as argument. The problem is that the implementation of Consumer Interface is an anonymous class and is clumsy.

pointList.forEach(new Consumer<Point>() { 
        public void accept(Point p) { 
            p.move(p.y, p.x);
        } 
    });

lambdas make things so simply

 pointList.forEach(p -> p.move(p.y, p.x));
