本文介绍了一个简单的Java程序，用于将文件从GBK编码转换为UTF-8编码。通过具体代码实现，展示了如何读取和写入不同编码的文件，这对于处理中文乱码问题非常实用。

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;

public class ChangeCode {

public void changeFile() {
  File f = new File("d:/test.txt");
  try {
   FileOutputStream fos = new FileOutputStream(f);
   OutputStreamWriter ws = new OutputStreamWriter(fos, "gbk");
   String r = new String("测试编码轮换是否正确".getBytes(), "gbk");
   ws.write(r);
   ws.close();
   fos.close();
  } catch (Exception e) {
   e.printStackTrace();
  }
}

public void FileCode() {
  File file = new File("d:/test.txt");
  File file2 = new File("d:/test2.txt");
  try {
   FileInputStream fis = new FileInputStream(file);
   InputStreamReader sr = new InputStreamReader(fis);
   FileOutputStream fos = new FileOutputStream(file2);
   OutputStreamWriter wr = new OutputStreamWriter(fos, "utf-8");
   char[] ar = new char[1024];
   int len = 0;
   while ((len = sr.read(ar)) != -1) {
        wr.write(ar,0,len);
   }
   sr.close();
   fis.close();
   wr.close();
   fos.close();
  } catch (Exception e) {
   e.printStackTrace();
  }
