Question#2: In class, we studied that Bridge pattern and discussed the Shape example below. Implement this example in Java. Assume that we want to control the thickness of Shape, i.e., to set the thickness to either Thick or Thin. Add a getter method for Colour and getters and setters to control the thickness. Then write a main method, in which you instantiate four instances of Shape, 2 Rectangle and 2 Triangle: a red thick and a blue thin triangle, and a red thin and a blue thick rectangle. Call the toString( method on all instances to print their colour and thickness. Shape IColour +setColour(IColour c) Red Blue Rectangle Triangle
