java代码如何实现List，Set，数组之间互相转换呢？

数组转list

String[] str = new String[]{"java265.com-1","java265.com-2"};
List list = Arrays.asList(str);

数组转set

String[] str = new String[]{"java265.com-1","java265.com-2"};
Set<String> set = new HashSet<>(Arrays.asList(str));

list转数组

Object[] res = list.toArray();

list转Set

Set res = new HashSet(list);

Set转数组

Object[] res = set.toArray();

Set转List

List<String> result = new ArrayList<>(set);
