Comparable 是排序接口 若一个类实现了Comparable接口,就意味着“该类支持排序”。此外,“实现Comparable接口的类的对象”可以用作“有序映射(如TreeMap)”中的键或“有序集合(TreeSet)”中的元素,而不需要指定比较器。 接口中通过x.compareTo(y)来比较x和y的大小。若返回负数,意味着x比y小;返回零,意味着x等...
What is sequential? Sequential, in the context of technology and computing, refers to a process or set of operations that occur in a specific order, one after the other. It's like reading a book from start to finish, where you go through each chapter one by one. ...

【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。
