java - 如何在文本文件中保留句子、行空间和段落

Question

我必须创建一种方法，可以从不同格式的文本文件中获取单词，然后在操作后按原样输出它们。

操作是将每个单词变成Piglatin。

例如：输入（从文本文件读取）：我有一只小青蛙，输出（由 printwriter）：Iway avehay away ittlelay ogfray，

我已经可以在 PigLatin 中自己转换单词，但是如何将文件放回原处（带有原始句子和空格）？

while(infile.hasNext()){
         String str2 = infile.next();
         String[] arr = str2.split(" ");
         String[] newArr = new String[arr.length];
         for(int k = 0; k < arr.length; k++){
            newArr[k] = pig(arr[k]);
         }
         for(int i = 0; i < newArr.length; i++){
            outfile.println(" " + newArr[i] + " ");
         }
      }
      outfile.close();
      infile.close();
   }

我所拥有的只是将单词放在每一行上。pig(String s) 将单词转换为 pig latin.outfile 写入输出文件，infile 从原始文本文件中读取，如下所示。

文本文件如下：

pig
latin

this 
strange

I have a little frog,
His name is Jim.

I love him very much, 
And when he sees me
He knows it!
