針對(duì)txt文件的讀寫可以使用java的讀寫操作。以下是一個(gè)簡(jiǎn)單的例子：

import java.io.BufferedReader;

import java.io.BufferedWriter;

import java.io.FileInputStream;

import java.io.FileNotFoundException;

import java.io.FileOutputStream;

import java.io.IOException;

import java.io.InputStream;

import java.io.InputStreamReader;

import java.io.OutputStream;

import java.io.OutputStreamWriter;

public class TXTReaderAndWriter {

public static void main(String args[]) {

String path = "test.txt";

readtxt(path);

writetxt(path);

}

private static void readtxt(String path) {

try {

InputStream in = new FileInputStream(path);

BufferedReader br = new BufferedReader(new InputStreamReader(in,

"gb2312"));

String tmp = "";

while ((tmp = br.readLine()) != null) {

System.out.println(tmp);

}

br.close();

in.close();

} catch (FileNotFoundException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

}

private static void writetxt(String path) {

try {

OutputStream ou = new FileOutputStream(path);

BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(ou,

"gb2312"));

BufferedReader br = new BufferedReader(new InputStreamReader(

System.in, "utf-8"));

String tmp = "";

while ((tmp = br.readLine()) != null && !tmp.equals("exit")) {

bw.write(tmp);

bw.flush();

bw.newLine();

}

br.close();

bw.close();

ou.close();

} catch (Exception e) {

e.printStackTrace();

}

}

}
