Java文件读写操作指定编码方式。。。。。

读：

File file=new File(this.filePath);
BufferedReader br=new BufferedReader(new InputStreamReader(new FileInputStream(file),"utf-8"));

String line=null;
while((line=br.readLine())!=null){
if(!line.trim().equals("")){
if(checkDuplicateRow(line.trim()))
tempList.add(line.trim());
}
}

写：

File filename = new File("xxx");
filename.createNewFile();
FileWriter fw = new FileWriter(filename);

PrintWriter out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(new FileOutputStream(filename),"GBk")));
out.write(hexToString(search_result));
out.flush();
out.close();
