【Java8】 方法引用 讲解 一、概述 在学习 lambda 表达式之后,我们通常使用 lambda 表达式来创建匿名方法。然而,有时候我们仅仅是调用了一个已存在的方法。如下: Arrays.sort(stringsArray,(s1,s2)->s1.compareToIgnoreCase(s2)); 在Java8中,我们可以直接通过方法引用来简写 lambda表达式中已经存在的方法。
Java虚拟机在执行Java程序的过程中会把它锁管理的内存划分为若干哥不同的数据区域,主要有程序计数器,虚拟机栈,本地方法区,虚拟机堆,方法区(运行时常量池),直接内存。 私有区 程序计数器 较小的内存空间,主要记录当前线程执行的字节码的行号指示器,各个线程之间独立存储互不影响。一个线程只有一个。
