Part 2: Write a JavaFX program that simulates a traffic light as shown below. The program should let the user to select one of three lights: RED, YELLOW, or GREEN. When a radio button is selected, the light is turned on and only one light can be on at a time. When the program starts no light should be on. E Traffic Lights Traffic Lights Red Red Vellow Yellow Green Green Hints: 1. You need to draw three circles inside a rectangle to represent the traffic lights. You may use the following code segment: // Create lightsPane Pane lightsPane = new Pane (): Circle redcircle = nev Circle (100, €0, 20) : Circle yellowCircle = nev Circle (100, 11o, 20) : Circle greenCircle = nev Cirele (100, 160, 20) : redCircle.setStroke (Color.BLACK) : redCircle.setFill (Color.WHITE): yellowCircle.setStroke (Color.BLACK) : yellowCircle.setfill (Color.WHITE) : greenCircle.setStroke (Color.BLACK) : greenCircle.setFill (Color.WHITE) : Rectangle rectangle = nev Rectangle (65, 25, 70, 170) : rectangle.setStroke (Color.BLACK) : rectangle.setFill (Color.WHITE): lightsFane.getChildren ().addall (rectangle, redCircle, yellovcirele, greenCircle): 2. You need to create three radio buttons. Do you need to group the three buttons in one group? Why ToggleGroups are used for? 3. You need to process the radio buttons' events to turn on the selected light.
