<h1 style="color: black; text-align: left; margin-bottom: 10px;">静态与动态</h1>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">静态和动态是两种<span style="color: black;">区别</span>的</span><strong style="color: blue;"><span style="color: black;">编程范式</span></strong><span style="color: black;">,它们影响了编程语言的设计和<span style="color: black;">运用</span>。Python是全动态的,它<span style="color: black;">能够</span>在运行时修改自己的代码,<span style="color: black;">这般</span><span style="color: black;">能够</span><span style="color: black;">增多</span>灵活性和创造性。而Java只能<span style="color: black;">经过</span><span style="color: black;">有些</span>变通的<span style="color: black;">办法</span>实现这一点,<span style="color: black;">例如</span>反射(reflection)和注解(annotation)。Python的变量是动态的,<span style="color: black;">亦</span><span style="color: black;">便是</span>说你不<span style="color: black;">必须</span>提前告诉计算机变量的类型,计算机会自动判断。</span></span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">而Java的变量则<span style="color: black;">必须</span>在<span style="color: black;">运用</span>之前进行<span style="color: black;">知道</span>的声明,<span style="color: black;">亦</span><span style="color: black;">便是</span>说你<span style="color: black;">必须</span>告诉计算机变量的类型。这<span style="color: black;">亦</span><span style="color: black;">寓意</span>着Java的集成<span style="color: black;">研发</span>环境(IDE)在代码提示方面要优于Python的IDE,<span style="color: black;">由于</span>Java<span style="color: black;">能够</span><span style="color: black;">按照</span>变量类型给出<span style="color: black;">更加多</span>的<span style="color: black;">意见</span>。</span></span></p>
<h1 style="color: black; text-align: left; margin-bottom: 10px;">历史和设计哲学</h1>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">历史和设计哲学决定了编程语言的</span><strong style="color: blue;"><span style="color: black;">特色和风格</span></strong><span style="color: black;">。Python<span style="color: black;">已然</span>存在了几十年,最初面向过程编程(procedural programming)是主流。面向过程编程<span style="color: black;">便是</span><span style="color: black;">根据</span>一系列<span style="color: black;">过程</span>来<span style="color: black;">处理</span>问题,比较简洁直观。<span style="color: black;">因此呢</span>,许多Python程序仍然<span style="color: black;">运用</span>面向过程的设计<span style="color: black;">办法</span>,许多概念来自于C语言。</span></span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">相反,Java的设计<span style="color: black;">目的</span>是填补C++中的不足,<span style="color: black;">重点</span>采用面向对象编程(OOP)<span style="color: black;">办法</span>。面向对象编程<span style="color: black;">便是</span>把问题分解成若干个对象,并让对象之间互相交互,比较抽象优雅。<span style="color: black;">因此呢</span>,许多Java程序都<span style="color: black;">运用</span>面向对象的设计<span style="color: black;">办法</span>,许多概念是面向对象编程(OOP)的概念。</span></span></p>
