        InputStream inputStream=null;

        String filedata="aaaa";
        Writer writer = null;
        BufferedWriter bufferedWriter = null;
        try {
            inputStream = new FileInputStream(cut1);
              bufferedInputStream = new BufferedInputStream(inputStream);
                byte[] b = new byte[1024];
                int count = 0;
                while((count = bufferedInputStream.read(b, 0, 1024))!=-1){
                    filedata=filedata+new String(b, 0, count);
                }
                writer = new FileWriter(cut3);
                bufferedWriter = new BufferedWriter(writer);
                bufferedWriter.write(filedata);
        } catch (FileNotFoundException e) {
            
            e.printStackTrace();
        } catch (IOException e) {
            
            e.printStackTrace();
        }
        finally{
            try {
                bufferedInputStream.close();
                inputStream.close();
                bufferedWriter.close();
                writer.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        cut1.delete();
}


      
        
    }

运行结果：
