Java：返回时对用户输入数组进行排序

Question

如何对以下内容进行排序？

System.out.println("Title: " + titleArray[x].getBook());

此行从用户输入的标题中获取其数据。如果我试试

System.out.println("Title: " + Arrays.sort(titleArray[x].getBook()));

我收到以下错误：

  LibraryBookSort.java:66: error: no suitable method found for sort(String)
          System.out.println("Title: " + Arrays.sort(titleArray[x].getBook()));

我假设这是由于构造函数在返回时不允许排序？ java.util.Arrays中;也是进口的。

编辑：尝试String sortedTitles [] = titleArray [x] .getBook（）;在Sysout之外为了建立一个新的字符串[]，收到以下错误......

  LibraryBookSort.java:63: error: incompatible types
        String sortedTitles[] = titleArray[x].getBook();
                                                     ^
  required: String[]
  found:    String
