So I have spent some time on this....
Write a program named TrafficLightcontroller
Program should have a main method
Construct three TrafficLight objects named:light1,light2,light3
Repeatedly print a menu that allows a user to type in responses and control the three lights.
Menu:
Select traffic light (0 to quit): 1
1)change traffic light 1
2)get current value for traffic light 1
3)set current value for traffic light 1
Enter choice: 2
Traffic light 1 is green
Select traffic light (0 to quit): 3
1)change traffic light 3
2)get current value for traffic light 3
3)set current value for traffic light 3
Enter choice: 1
Traffic light 3 went from yellow to red.
Select traffic light (0 to quit): 2
1)change traffic light 2
2)get current value for traffic light 2
3)set current value for traffic light 2
Enter choice: 3
Traffic light 2 is now green.
1)make traffic light 2 green
2)make traffic light 2 yellow
3)make traffic light 2 red
Enter choice: 3
Traffic light 2 is now green.
Select traffic light (0 to quit): 0
I am confused a bit and lost:
public class TrafficLight {
private int changeLight;
private int getLightColor;
private int setLightColor;
private int trafficLight1;
private int trafficLight2;
private int trafficLight3;
private int selectLight;
private int enterChoice;
public TrafficLight();
changeLight = 1
getLightColor=2;
setLightColor=3;
trafficLight1=Green;
trafficLight2=Yellow;
trafficLight3=Red;
}
public static void main (String [] args){
trafficLight1=new TrafficLight();
System.out.print("Select traffic light (0 to quit) : ")
int selectLight=Keyboard.readInt();
if (selectLight ==1)
System.out.prinln("1) change traffic light 1")
System.out.println("2) get current value for traffic light 1")
System.out.println("3) set current value for traffic light1")
System.out.print("Enter choice: \n")
int enterChoice=Keyboard.readInt();
