    private ArrayList<Book> booklist;

    public Borrower(String[] info) {
        this.setName(info[0]);
        this.setId(Integer.parseInt(info[1]));
        this.setAge(Integer.parseInt(info[2]));

        this.booklist = new ArrayList<Book>();
        if(info.length == 5) { 
            this.booklist.add(new Book(info[3], info[4], ""));
        } else if(info.length == 6) { 
            this.booklist.add(new Book(info[3], info[4], info[5]));
        } else if(info.length == 7) { 
            this.booklist.add(new Book(info[3], info[4], ""));

    public String getName() {
        return name;

    }
    public int getId() {
        return id;

    public ArrayList<Book> getBooklist() {
        return booklist;
    }
    public boolean addBook(Book book) {
        if(this.booklist.size() < 2) {
            this.booklist.add(book);

            this.booklist.remove(0);
            return true;
        }
        return false;
    }

    public String toString() {
        StringBuilder sb = new StringBuilder();
        sb.append(this.getName());
        sb.append("," + this.getId());
        sb.append("," + this.getAge());
        for(Book book : booklist) {
            sb.append("," + book);
        }
        return sb.toString();
    }
}

以这种方式写下

{"Arvind" , "1" , "2"}

在对话框中输入以上内容。 基本上{}是缺少的标识符。
