Java文件读写核心代码

FileChannel fci =  new FileInputStream("e:\\yang.iso").getChannel();FileChannel fco = new FileOutputStream("e:\\gao.iso").getChannel();ByteBuffer bf = ByteBuffer.allocate(2048);while(fci.read(bf) != -1){bf.flip();fco.write(bf);bf.clear();}fco.close();fci.close();

?说明:nio中方法好像比io中的更简洁，且更快!
