java中如何将map转换为list呢？

实现思路:
    使用keySet() 将key放入list中
	使用values() 将value放入list中

package com.java265.other;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.Map;
public class Test16 {
	/**
	 * java265.com 示例程序
	 */
	public static void main(String... args) {

		Map<Integer, String> map = new HashMap<>();
		map.put(1, "java265.com");
		map.put(2, "java265.com-2");
		map.put(3, "java265.com-3");

		System.out.println("HashMap = " + map);
		System.out.println("=================");
		ArrayList<Integer> key = new ArrayList<Integer>(map.keySet());
		ArrayList<String> value = new ArrayList<String>(map.values());
		System.out.println("List (Map Keys) = " + key);
		System.out.println("List (Map Values) = " + value);
	}
}
------------运行以上代码，将输出以下信息------
HashMap = {1=java265.com, 2=java265.com-2, 3=java265.com-3}
=================
List (Map Keys) = [1, 2, 3]
List (Map Values) = [java265.com, java265.com-2, java265.com-3]
