  • 数组,List,Set相互转化

    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);
