private char cb[];
private static int defaultCharBufferSize = 8192;
}

BufferedOutputStream out = new BufferedOutputStream(new FileOutputStream("f5"));
out.write(97);
out.write(98);
out.write(99);
out.flush();//刷出缓存数据
//高级流close()
//1.flush()2.关闭相接的流
System.out.println("写入完成!");
out.close();
}
}
运行结果
写入完成!
