本文详细介绍了如何使用Java进行UTF-8编码的文件读写操作，包括以UTF-8格式写入数据到文件及从文件读取UTF-8编码的内容，帮助开发者解决字符集问题。

以utf-8编码写入文件：

FileOutputStream fos = new FileOutputStream("test.txt");   
OutputStreamWriter osw = new OutputStreamWriter(fos, "UTF-8");   
osw.write(FileContent);   
osw.flush();

以utf-8编码读取文件：

FileInputStream fis = new FileInputStream("test.txt");   
InputStreamReader isr = new InputStreamReader(fis, "UTF-8");   
BufferedReader br = new BufferedReader(isr);   
String line = null,FileContent = "";   
while ((line = br.readLine()) != null) {   
    FileContent += line;   
    FileContent += "\r\n";  
}
