IO流的读写操作

public class ByteFile {

public void writeToFile(byte[] buffer) throws IOException

System.out.print(buffer[i]+" ");
System.out.println("count="+count);

}
fin.close();
fout.close();
System.out.println("CopyFile from"+this.filename+" to "+filename2);
}
public static void main(String[] args) throws IOException{
byte[] buffer={0,1,2,3,4,5,6,7,8,9};
ByteFile afile=new ByteFile("f:\\test\\aa.txt");
afile.writeToFile(buffer);
afile.readFromFile();
afile.copyFile("f:\\test\\cc\\zz.txt");
}
}
这段代码所操作的文件的写入的文件内容为Ā̂Ԅ܆ई是什么意思啊，求解释？
