[CLO-1] Consider the class Pen. It has a color (String) and a length (double). It has an initialization constructor, a default constructor, setters and getters, and a toString() method. Assume this class is given (i.e. do not write the class methods).

In another class Main, write a method displayPens(Pen[] array) that receives an array of Pen objects, and displays only the pens with "Red" color and length that is between 20 and 30 cm.
