1. 数组转化为List:
String[] strArray= new String[]{"Tom", "Bob", "Jane"};
List strList= Arrays.asList(strArray);
2. 数组转Set
String[] strArray= new String[]{"Tom", "Bob", "Jane"};
Set<String> staffsSet = new HashSet<>(Arrays.asList(staffs));
staffsSet.add("Mary"); // ok
staffsSet.remove("Tom"); // ok
3. List转Set
String[] staffs = new String[]{"Tom", "Bob", "Jane"};
List staffsList = Arrays.asList(staffs);
Set result = new HashSet(staffsList);
4. set转List
String[] staffs = new String[]{"Tom", "Bob", "Jane"};
Set<String> staffsSet = new HashSet<>(Arrays.asList(staffs));
List<String> result = new ArrayList<>(staffsSet);
