C与Java从编程思想上来说彻底不同. Java是纯面向对象言语,用虚拟机解说履行,速度十分慢,大约是同等C言语程序速度的1/60。优点是程序履行和操作系统无关。十分合适在网络上运用。 C是面向进程的言语，编译出的程序和硬件，操作系统相关。程序运转功率十分高。好的C程序最多比相同的汇编程序慢10%. 两种言语入门都很简单。要想用好仍
需继承LruCache,实现自己的LRU缓存。lowSpeedStorage是提供给你可用的低速存储,你不需要实现它。 https://github.com/swgithub1006/mqlearning https://gist.github.com/imgaoxin/ed59397c895b5a8a9572408b98542015
从而通过各自对映射区域的改动,达到进程间通信和进程间共享的目的。 同时,如果进程A和进程B都映射了区域C,当A第一次读取C时通过缺页从磁盘复制文件页到内存中;但当B再读C的相同页面时,虽然也会产生缺页异常,但是不再需要从磁盘中复制文件过来,而可直接使用已经保存在内存中的文件数据。 4、可用于实现高效的大...

Java speed As a compiled language, Java is naturally faster than JavaScript when run on a virtual machine. Even when JavaScript closed that gap with JIT compilation, there is still the matter of Java’s built-in support for multithreading and concurrency. The ability to run processes in paralle...
我和另外两名同学用vs2022和自带的easyx图形工具共同完成了这坨代码(别问为啥不用Qt啥的) 总体设计 1.思路介绍 瞎设计的,总之能跑。也不能说完全没有设计思绪,如图: 这俩图差不多,第二个是我画的,更注重图形管理这块,有一些各类的功能介绍。 所幸有设计思路,我们按照分模块的方法分工协作,将项目分为CShape...
