String的实现位于包java.lang.String。这里简单列举一下对本篇文章有用的代码: public final classString { /** The value is used for character storage. */ private final charvalue[]; /** * Initializes a newly created {@code String} object so that it represents * an empty character sequence. N...
类的初始化(Initialize) JVM负责对类进行初始化。 ①执行类构造器<clinit>()方法的过程。类构造器< clinit> ()方法是由编译期自动收集类中所有类变量的赋值动作和静态代码块中的语句合并产生的(类构造器是构造类信息的,不是构造该类对象的构造器)。 ②当初始化一个类的时候,如果发现其父类还没有进行初始化,则...
