它讀取文件，但它將文件發送到新文件時沒有正確打印？

Question

將文件讀取到新文件時，我遇到了問題。因此，這裏的來自財務文件中的示例數據：

資本

2215.281234

韋弗，艾迪U.

902-6238普魯斯大道

利息

22343.623428

弗羅斯特，塔娜Y.

P.O.盒902，3494 Enim路

當我跑了，所有我得到的是：

名稱：

地址：

等

打完了 「名」或「地址」，它不顯示相應的名稱或添加該稅碼。但是，它讀取文件寫入;它不會在屏幕上或文件中打印名稱和地址。如果有人能幫助我，我將不勝感激。印刷是我唯一的問題。提前致謝。

printf行錯了。請使用下面一行代替。

System.out.printf("Name: %s\nAddress: %s\n", name, address); 

有什麼問題你行，你把這個字符串"Name: "和"Address: "作爲參數printf，使它們被用來取代2 %s。
