JAVA程序:UTF码进行文件的读写_java utf码-优快云博客

本文提供了一个使用Java进行文件读写的示例程序。通过该程序可以了解到如何使用FileOutputStream、BufferedOutputStream和DataOutputStream来写入UTF编码的字符串到文件中；同时，也展示了如何利用FileInputStream、BufferedInputStream及DataInputStream从文件中读取UTF编码的字符串。

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;

public class TestStream {

public static void main(String[] args) {

  try{
   FileOutputStream fileOutputStream = new FileOutputStream("f://001.txt");
   BufferedOutputStream bufferedOutputStream = new BufferedOutputStream(fileOutputStream);
   DataOutputStream dataOutputStream = new DataOutputStream(bufferedOutputStream);

   dataOutputStream.writeUTF("中国");
   dataOutputStream.writeUTF("美国");
   dataOutputStream.writeUTF("日本");
   dataOutputStream.close();

   FileInputStream fileInputStream = new FileInputStream("f://001.txt");
   BufferedInputStream bufferedInputStream = new BufferedInputStream(fileInputStream);
   DataInputStream dataInputStream = new DataInputStream(bufferedInputStream);

   System.out.println(dataInputStream.readUTF());
   System.out.println(dataInputStream.readUTF());
   System.out.println(dataInputStream.readUTF());

  }catch(Exception e){
   e.printStackTrace();
  }
}
}
