从 Hashmap put() 获取调用方法名称列表

Question

你能帮我从 HashMap put 方法中获取列表方法名称吗？

 Book book= new Book();
        book.setTitle("The Little Prince");
        book.setAuthor("Antoine de Saint-Exupery");
        book.setPrize(9.99);
        book.setPublisher("Delux Pop-up book");
        
        
        HashMap<String,String> map= new HashMap<String,String>();
        map.put("title",book.getTitle());
        map.put("author",book.getAuthor());
        map.put("prize",String.valueOf(book.getPrize()));
        map.put("publisher",validatePuplisher(book.getPublisher()));
        

例外结果是： book.getTitle(),book.getAuthor(),String.valueOf(book.getPrize()),validatePuplisher(book.getPublisher())即只是方法名称不是方法中的值。

如果要获取使用的方法名称，请将它们括在双引号中以被视为实际字符串。

 HashMap<String,String> map= new HashMap<String,String>();
        map.put("title","book.getTitle()");
        map.put("author","book.getAuthor()");
        map.put("prize","book.getPrize()");
        map.put("publisher","book.getPublisher()");
