【Java】07 FlowControl 流程控制 FlowControl 流程控制 什么是流程控制? 控制流程(也称为流程控制)是计算机运算领域的用语,意指在程序运行时,个别的指令(或是陈述、子程序)运行或求值的顺序。 不论是在声明式编程语言或是函数编程语言中,都有类似的概念。 基本的三种流程结构: - 顺序结构,自上而下的一般结构 -...
可以使用Collection接口的stream 或者 parallelStream 创建并行流 如果参数是数组也可以是使用Stream.of方法创建 Stream<String> song=Stream.of("gently","down","the","stream") 1. Array.stream(arry,form,to)可以从数组中位于from包括到to不包括的元素中创建一个流 Stream.empty() 创建不包含任何元素的流 Stre...
Java 流程控制语句(Control Flow) 选择意味着取舍——Miao酱程序设计中有三种流程结构,即: 顺序结构 程序从上到下逐行地执行,中间没有任何判断和跳转。 分支结构 根据判断条件,选择性地执行某段代码。 有if…else和switch-case两种分支语句。 循环结构 根据循环条件,重复性的执行某段代码。 有for、while、do...
Java, like most other languages, offers conditional flow logic for the program execution. A set of statements may be executed once, more than once, or skipped altogether, and the decision may be made at runtime (that is, at the time of program execution). This makes programming more ...

In Java, a control flow statement can be one of the following: A selection statement:if-elseorswitch-case An iteration statement:for,whileordo-while An exception-handling statement:throwortry-catch-finally A branching statement:break,continue,return,yield, orlabeled statements ...
If the items attribute is of type java.util.Map, then the current item will be of type java.util.Map.Entry, which has the following properties:key: The key under which the item is stored in the underlying Map value: The value that corresponds to the key ...
6.8 控制流语句(Control Flow Statement) 程序最小的独立单元是语句(statement),语句一般由分号结尾,缺省情况下,语句是顺序执行的,但是当涉及逻辑判断控制时,就要求有控制流程序语句。控制流程序语句分为条件语句和循环语句,在C语言中,条件语句有if、if-else、switch等,而循环过程则由while、do-while和for语句支持。
