Java8-数组转其它格式

@Test
public void ArrayToOthers() throws Exception {

    int[] arrInt = {1, 2, 3, 4};

    // ArrrayInt数组转化为字符串
    String intStr = Arrays.stream(arrInt).boxed().map(item -> item.toString()).collect(Collectors.joining(","));
    System.out.println("ArrrayInt数组转化为字符串 = " + intStr);

    // ArrrayInt数组转化为List集合
    List<Integer> arrayIntToList = Arrays.stream(arrInt).boxed().collect(Collectors.toList());
    System.out.println("ArrrayInt数组转化为List集合 = " + arrayIntToList);

    /***********************************************************************************************************************************/
    String[] arrStr = {"apple", "banana", "per"};

    String strStr = Arrays.stream(arrStr).collect(Collectors.joining(","));
    System.out.println("ArrrayStr数组转化为字符串 = " + strStr);

    List<String> arrayStrToList = Arrays.stream(arrStr).collect(Collectors.toList());
    System.out.println("ArrrayStr数组转化为List集合 = " + arrayStrToList);
