enum OperatingSystems {
windows, unix, linux, macintosh
}

public class EnumExample1 {
public static void main(String args[])
{
OperatingSystems os;

os = OperatingSystems.windows;
switch(os) {
case windows:
System.out.println(“You chose Windows!”);
break;
case unix:
System.out.println(“You chose Unix!”);
break;
case linux:
System.out.println(“You chose Linux!”);
break;
case macintosh:
