Hi,

Could you please help?? I am tired and confused. I don't what to do any more! I am trying to write a traffic simulation and i wrote some interface and some classes but the main one that has a big chunk of code seems to me like nightmare. Certainly it is confusing and doesn't make sense. I have three lights that have green yellow and red. I wrote three classes westligh, southlight and eastlight implementing threads so that there a pause for each of them. I have to code when a car is running it has to stop for any obstruction such a car infront of it, or a red light. The light have different timing such the first one 30 second for red 5 for yellow and 45 for green. the next cross light has 50 for red 5 for yellow and 25 for green. The simulation is run base on the time given by the user. Now i though i can use the Date class. Still how to tell if it is first second do this and if it is the second second do that...... I will paste my confusing code for class Car.java. Please help me with this and tell me what could i improve and how to use the Date class and this the wright way to move a car? Thank you very much and Here is the code:
