Domain objects are usually complex. Making a copy with the root object and composed objects is also not trivial. Let's explore the most effective ways to copy an object using shallow and deep copy techniques.

2023-10-08 3 简介： 缓冲流的基本原理，是在创建流对象时，会创建一个内置的默认大小的缓冲区数组，通过缓冲区读写，减少系统IO次数，从而提高读写的效率。 六、缓冲流 概述 缓冲流,也叫高效流，是对4个基本的FileXxx 流的增强，所以也是4个流，按照数据类型分类： 字节缓冲流：BufferedInputStream，BufferedOutputStream 字符缓冲流：BufferedReader，BufferedWriter 缓冲流的基本原理，是在创建流对象时，会创建一个内置的默认大小的缓冲区数组，通过缓冲区读写，减少系统IO次数，从而提高读写的效率。 字节缓冲流 构造方法： public BufferedInputStream(InputStream in) ：创建一个 新的缓冲输入流。 public BufferedOutputStream(OutputStream out)： 创建一个新的缓冲输出流。 示例： 缓冲流示例： 字符缓冲流 构造方法 public BufferedReader(Reader in) ：创建一个 新的缓冲输入流。 public...
