提要:本文从实现原理的角度上阐述和剖析了:在Java语言中,以String作为类型的变量在作为方法参数时所表现出的“非对象”的特性。 一、最开始的示例 写代码最重要的就是实践,不经过反复试验而得出的说辞只能说是凭空遐想罢了。所以,在本文中首先以一个简单示例来抛出核心话题: public class StringAsParamOfMethodDemo ...

不可变类,并在对象的整个生命周期(lifetime)内保持不变。Java平台类库中包含许多不可变的类,其中有String、基本类型的包装类、BigInteger、BigDecimal。 为了使类成为不可变,要遵循下面五条规则: 1.不要提供任务会修改对象状态的方法。 2.保证类不会被扩展。常见做法final Class、 private constructor并添加公有的静态...
