Day yesterday = Day.Thursday;
Day today = Day.Friday;
Day tomorrow = Day.Saturday;
System.out.println("Today is " today);
System.out.println("Tomorrow will be " tomorrow);
System.out.println("Yesterday was " yesterday);

}
public class one{
public static void main(String[] args) {
Day yesterday = Day.Thursday;
Day today = Day.Friday;
Day tomorrow = Day.Saturday;
System.out.println("Today is " today);
System.out.println("Tomorrow will be " tomorrow);
System.out.println("Yesterday was " yesterday);

public class one {
enum Day { Monday, Tuesday, Wednesday, Thursday, Friday, Saturday,Sunday};
public static void main(String[] args) {
Day yesterday = Day.Thursday;
Day today = Day.Friday;
Day tomorrow = Day.Saturday;
System.out.println("Today is "+today);
System.out.println("Tomorrow will be "+tomorrow);
System.out.println("Yesterday was "+yesterday);
}
}
====================================================================
the above code works...it workd on mine...declared enum Day global to the class one..hence declared it jus b'fo main().
