我的想法是按字符长度读取一个文本文件的内容，
先读取0~2000个字符，再读取2001~4000的字符！
然后分别保存为每个小文件，以此类推！
请问该怎么实现？
------解决方案--------------------
可以参考如下代码
file的地址可以自己填进去,新建的文件名自己也可以更改
size就是你想读取的字符个数
- Java code
package com.ray.tests.cutfile;import java.io.BufferedReader;import java.io.BufferedWriter;import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.IOException;import java.io.InputStreamReader;import java.io.OutputStreamWriter;public class CutFile { public static void main(String[] args) throws IOException { cutFile("src/com/ray/tests/cutfile/file.txt", 2000); } public static void cutFile(String fileName, int size) throws IOException { BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream(fileName))); int len; int count = 1; char[] cbuf = new char[size]; while ((len = reader.read(cbuf, 0, size)) != -1) { BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(fileName + "_" + count))); writer.write(cbuf, 0, len); writer.flush(); writer.close(); count++; } }}
