1.1. 顺序结构 在Java中,顺序结构的语句是指按照代码从上到下的顺序逐行执行的语句。这种结构是编程中最基本、最自然的流程控制方式。在顺序结构中,每个语句都是按照它们在代码中出现的顺序依次执行的,没有任何跳转或条件分支。 以下是一个简单的Java程序,展示了顺序结构的语句: public class SequentialExample { pub...

迭代器是一种scanning through一系列元素,每次一个的一种软件设计模式。底层的迭代元素可能是被一个容器类所存储,也有可能是经过一系列的运算生成的。 Java针对迭代器定义了java.util.iterator接口,定义有如下2个方法: 这个接口使用了java的泛型变成,next方法会返回一个参数化的元素。 如果next方法在容器中没有元素 ...

for (Object o : collection) System.out.println(o); Iterators AnIteratoris an object that enables you to traverse through a collection and to remove elements from the collection selectively, if desired. You get anIteratorfor a collection by calling itsiteratormethod. The following is theIterator...
The edition of the Java platform that is targeted at small, standalone or connectable consumer and embedded devices to enable development, deployment, and management of applications that can scale from smart cards through mobile devices and set-top boxes to conventional computing devices. * Java ...
an old object garbage collection must be performed. The Java HotSpot VM by default uses a standard mark-compact collection algorithm, which traverses the entire graph of live objects from itsroots, then sweeps through memory, compacting away the gaps left by dead objects. By compacting gaps in...
Iterating through collections offers you another chance to have a bit of fun with the for loop. Let’s begin with typical code used to iterate through a collection of objects: package oreilly.hcj.review; public class ForLoops { public static void forLong( ) { Properties props = System.get...
