As we saw in the previous examples, it’s very verbose to use anIteratorwhen we just want to go over all the elements and do something with them. Since Java 8, we have theforEachRemainingmethod that allows the
想遍历ArrayList里面的内容,通常先生成一个“迭代器”(Iterator), 之后利用它里面的iterator()方法,马克-to-win:Iterator就像一面镜子,能照出集合类中的内容。通过遍历,能得到集合类中的内容。 例:1.1.2 import java.util.ArrayList; import java.util.Iterator; public class TestMark_to_win { public static v...
Use an iterator to remove numbers less than 10 from a collection: import java.util.ArrayList; import java.util.Iterator; public class Main { public static void main(String[] args) { ArrayList<Integer> numbers = new ArrayList<Integer>(); numbers.add(12); numbers.add(8); numbers.add(2);...

Java集合——集合框架Iterator接口 1.集合输出 很多情况下我们需要把集合的内容进行输出,也就是遍历集合。 遍历集合的方式有以下几种: 1.Iterator 2.ListIterator 3.Enumeration(枚举方式,比较老一般不用) 4.foreach 5.传统for循环 其中Iterator的使用率最高。
An iterator over a collection.Iteratortakes the place ofEnumerationin the Java Collections Framework. Iterators differ from enumerations in two ways: Iterators allow the caller to remove elements from the underlying collection during the iteration with well-defined semantics. ...
