如何实现数组和List之间的转换？

public static void testArray2List() {
    String[] strs = new String[] {"aaa", "bbb", "ccc"};
    List<String> list = Arrays.asList(strs);
    for (String s : list) {
        System.out.println(s);
    }
}

public static void testList2Array() {
    List<String> list = Arrays.asList("aaa", "bbb", "ccc");
    String[] array = list.toArray(new String[list.size()]);
    for (String s : array) {
        System.out.println(s);
    }
}
