Answer:

import java.util.Scanner;

public class Main{

public static void main(String[] args){

Scanner sc=new Scanner(System.in);

System.out.println("Enter the color");

String color=sc.nextLine();

String a="green";

String b="red";

String c="yellow";

if(a.equals(color))

{System.out.print("go");}

else if(b.equals(color))

{System.out.print("stop");}

else if(c.equals(color))

{System.out.print("proceed with caution");}

else

{System.out.println("prepare to go");}}}
