我怎样才能确定在java文件的每一行的字节数？ [英] How can I determine the number of bytes of each line of a file in java?

问题描述

我有一个非常大的文本文件。我想确定每一行的字节数，并保存在另一个文件中。

下面的代码提取

  byte [] chunks = null; 
 BufferedReader in = 
 BufferedReader（new InputStreamReader（new FileInputStream（path +/+ filePath），UTF-8））; 
 String eachLine =; （（eachLine = in.readLine（））！= null）
 
 {
 chunks = eachLine.getBytes（UTF-8）; 
 System.out.println（chunks.length）; 
} 
  

I have a very big text file. I want to determine the number of bytes of each line and save it in another file.

解决方案

The following code extracts

   byte[] chunks  = null;
        BufferedReader  in = 
        new BufferedReader (new InputStreamReader(new FileInputStream(path +"/"+filePath),"UTF-8"));
        String eachLine  = "";  
        while( (eachLine = in.readLine()) != null) 
        {
            chunks = eachLine.getBytes("UTF-8");
            System.out.println(chunks.length);
        }
