代码实现：

import java.util.Scanner;

enum Color {

red("Rose", "red"),
orange("Poppies", "orange"),
yellow("Sunflower","yellow"),
green("Grass", "green"),
blue("Bluebells", "blue"),
violet("Violets", "violet");

String name;
String color;

Color(String name, String color) {
this.name = name;
this.color = color;
}

public String toString() {
return name + " are " + color + ".";
}
}

public class Main {

public static void main(String[] args) {
Scanner input = new Scanner(System.in);
while (input.hasNext()) {
String inputColor = input.next();
try{
Color color = Color.valueOf(inputColor);
System.out.println(color);
}
catch(Exception e){
System.out.println("I don't know about the color "+inputColor+".");
}
}
}
}
