java - 如何使用java中的Scanner类将两个或更多单词存储在一个字符串变量中，然后将下一个输入存储在另一个字符串变量中？

Question

Scanner sc = new Scanner(System.in);

    System.out.println("Enter title of the book: ");
    String title = sc.next();
    System.out.println("Enter the author: ");
    String author = sc.next();

    String bookID = bookID();

    Book b = new Book(author,title,bookID,true);
    books.add(b);


    System.out.println( title + " by "+ author +" added to library.");
    System.out.println("Book ID: " + bookID);

这会产生以下输出，标题为“Gone with the Wind”，作者为 Margaret Mitchell:

Gone by with added to library
Book ID:456423156

有什么办法可以解决这个问题吗？

Answer 1

使用Scanner#nextLine()而不是 Scanner#next()。后者仅读取下一个标记分隔符，即 whitespace character of some sort默认情况下。
