//讀取
String fileFullPath = "C:\\Documents and Settings\\Irving\\桌面\\LOG_"+getClass().getName()+"_1.txt";
BufferedReader bf = new BufferedReader(new InputStreamReader( new FileInputStream(fileFullPath), "UTF-16LE"));

//寫入
String fileFullPath = "C:\\Documents and Settings\\Irving\\桌面\\LOG_"+getClass().getName()+"_1.txt";

BufferedWriter bw = new BufferedWriter(new OutputStreamWriter ( new FileOutputStream(fileFullPath), "UTF-8"));
            for(int w=0; w<listSQL.size(); w++) {//listSQL要寫入的東西
            bw.write(String.valueOf("第"+ (w+1) + "筆 \n"));
            bw.write(listSQL.get(w));
            bw.write("\r\n");
             bw.flush();
