java - Four Way Intersection Simulation -
i'm trying write program displays light sequences @ 4 way intersection.
the direcitons are:
at given time traffic can move in 1 direction. traffic lights have 3 colors red, yellow , green. based on event. lights change color in synchronized way allow safe driving. define class called “trafficlight” has 2 methods. 1 called “change” , called “getcolor”. in separate class “assignment5”, main entry point, want create 4 trafficlight instances 2 north/south traffic , 2 east/west traffic. using 2 methods objects provide want show have correctly simulated 4 way traffic light.
so far have:
public class trafficlight { /** * @param args */ public trafficlight(int c){ this.c = c; }//end constructor public int getc(){ return c; } java.lang.string getcolor; string n = "gyr"; string s = "gyr"; string e = "gyr"; string w = "gyr"; public void change(){ int c = 1; while (c <= 4){ if (c == 1){ n.charat(2); s.charat(2); e.charat(0); w.charat(0); c++; } else if (c == 2){ n.charat(2); s.charat(2); e.charat(1); w.charat(1); c++; } else if (c == 3){ n.charat(0); s.charat(0); e.charat(2); w.charat(2); c++; } else if (c == 4){ n.charat(1); s.charat(1); e.charat(2); w.charat(2); c++; } while (c >= 5) if (c-4 == 1){ n.charat(2); s.charat(2); e.charat(0); w.charat(0); c++; } else if (c-4 == 2){ n.charat(2); s.charat(2); e.charat(1); w.charat(1); c++; } else if (c-4 == 3){ n.charat(0); s.charat(0); e.charat(2); w.charat(2); c++; } else if (c-4 == 4){ n.charat(1); s.charat(1); e.charat(2); w.charat(2); c++; } system.out.println(n); system.out.println(s); system.out.println(e); system.out.println(w); }//end inner while loop }//end 'change' private int c; }//end class the sample output should like:
traffic light event 1: north light: red south light: red east light: green west light: green traffic light event 2: north light: red south light: red east light: yellow west light: yellow traffic light event 3: north light: green south light: green east light: red west light: red traffic light event 4: north light: yellow south light: yellow east light: red west light: red traffic light event 5: north light: red south light: red east light: green west light: green traffic light event 6: north light: red south light: red east light: yellow west light: yellow traffic light event 7: north light: green south light: green east light: red west light: red traffic light event 8: north light: yellow south light: yellow east light: red west light: red traffic light event 9: north light: red south light: red east light: green west light: green traffic light event 10: north light: red south light: red east light: yellow west light: yellow traffic light event 11: north light: green south light: green east light: red west light: red traffic light event 12: north light: yellow south light: yellow east light: red west light: red how go implementing this? thoughts?
