The task needs to be done in processing language code. your job is to Implement a class HappyFace : 1. A HappyFace has position x, y and radius r, all of float type. 2. A HappyFace has fill color and outline color. 3. Write a function display() that draws the face centered at (x, y). ■ The mouth is an arc with a diameter equal to 1.6 r. ■ The eyes are ellipses with dimensions r/2 * r/4 ■ The outline's thickness is r/20   Use the Happy Face class to create two different faces and display them on the sketch. 4. Use the dot operator to set the attributes. E.g.: ■ face1.x = width/2; ■ face1.y = height/2; ■ face1.r = width/4. ■ face1.fillColor = color(255, 255,0); 4. Add code to move the faces and bounce them off the sketch edges. Here is the non-OOP code: float x 50, y = 50, r = 20; fill(255,255,0); stroke (255,155,0); strokeWeight(r/20); ellipse(x,y,2*r, 2*r); //face arc(x,y,1.6*r, 1.6*r, .1*PI, .9*PI); //mouth ellipse (x+r/2,y-r/4,r/4,r/2); //right eye ellipse(x-r/2,y-r/4,r/4,r/2); //left eye
