Time Limit: 1000 ms Memory Limit: 65536 KiB

Problem Description

请定义具有red, orange, yellow, green, blue, violet六种颜色的枚举类型color，根据输入的颜色名称，输出以下六种植物花朵的颜色：
Rose(red), Poppies(orange), Sunflower(yellow), Grass(green), Bluebells(blue), Violets(violet)。如果输入的颜色名称不在枚举类型color中，例如输入purple，请输出I don't know about the color purple.

Input

输入数据有多行，每行有一个字符串代表颜色名称，颜色名称最多30个字符，直到文件结束为止。

Output

输出对应颜色的植物名称，例如：Bluebells are blue. 如果输入的颜色名称不在枚举类型color中，例如purple, 请输出I don't know about the color purple.

Sample Input

blue
yellow
purple

Sample Output

Bluebells are blue.
Sunflower are yellow.
I don't know about the color purple.

Hint

请用枚举类型实现。

枚举，由于Java枚举跟C有很大不同，所以打算试试，有很多不会的地方，列如枚举类的使用，try catch（Exception e）不会。
后期会回来补充。
借鉴:

• Java 枚举(enum) 详解7种常见的用法
• 简单枚举类型——植物与颜色(类)

import java.util.*;

enum Color//枚举类
{
	red("Rose","red"),
	orange("Poppies","orange"),
	yellow("Sunflower","yellow"),
	green("Grass","green"),
	blue("Bluebells","blue"),
	violet("Violets","violet");
	String color,name;
	Color(String name,String color)
	{
		this.name = name;
		this.color = color;
	}
	public String getcolor()
	{
		return name+" are "+color+".";
	}
}

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

}
