//文件创建
File FileDir=new File(fileNameAndpath);
try{
if(!FileDir.exists()){
FileDir.createNewFile();

            //向文件中传入信息
             WriterFileThread writerIn=new WriterFileThread(fileNameAndpath,fileContent,contentName);               
             Thread t=new Thread(writerIn);
             t.start();
             t.join();                   
             bool=t.isAlive();
             while(bool){
                 Thread.sleep(500);
             }
        }
    }
    catch(Exception e){
        e.printStackTrace();
    }
    --------------------------------------------------------------------------
    //文件写入信息
    StringBuilder stringHtml = new StringBuilder(); 
     OutputStreamWriter write;
          try {
            write = new OutputStreamWriter(new FileOutputStream(filePath), "UTF-8");
             BufferedWriter writer = new BufferedWriter(write);
             stringHtml.append("helloword”）；
             writer.write(stringHtml.toString());
               writer.flush();
               writer.close(); 

               System.out.println("ending");     
        } catch (UnsupportedEncodingException e) {              
            e.printStackTrace();
        } catch (FileNotFoundException e) { 
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
            System.out.println("ending1");
        }
          catch(Exception e){
              e.printStackTrace();
              System.out.println(""+e);
          }finally{
              System.out.println("end");
        }
          System.out.println("ending2");
