Java8-ListChangeString

public class ListChangeString {
 
    public static void main(String[] args) {
 
        List<String> list1 = Arrays.asList("文學","小說","歷史","言情","科幻","懸疑");
 
        List<String> list2 = Arrays.asList("文學","小說","歷史","言情","科幻","懸疑");
 
        //方案一：使用String.join()函數，給函數傳遞一個分隔符合一個迭代器，一個StringJoiner對象會幫助我們完成所有的事情
        String string1 = String.join("-",list1);
 
        System.out.println(string1);
 
        //方案二：採用流的方式來寫
        String string2 = list2.stream().collect(Collectors.joining("-"));
 
        System.out.println(string2);
    }
}

Java8-StringChangeList

public class StringChangeList {
    public static void main(String[] args) {
 
        String string= "文學-小說-歷史-言情-科幻-懸疑";
 
        List<String> list = Arrays.asList(string.split("-")).stream().map(s -> String.format(s.trim())).collect(Collectors.toList());
 
        System.out.println(list);
    }
}
