Java中AbstractList类的iterator()方法
iterator()AbstractList类的方法用于按适当顺序在此列表中的元素上返回迭代器。
语法如下
public Iterator<E> iterator()
在这里，迭代器是集合的迭代器。要使用AbstractList类，请导入以下包
import java.util.AbstractList;
以下是iterator()在Java中实现AbstractlList类的方法的示例
示例
import java.util.ArrayList;
import java.util.Iterator;
import java.util.AbstractList;
public class Demo {
public static void main(String[] args) {
AbstractList<Integer>
myList = new ArrayList<Integer>();
myList.add(75);
myList.add(100);
myList.add(150);
myList.add(200);
myList.add(250);
myList.add(150);
myList.add(150);
myList.add(400);
System.out.println("Elements in the AbstractList = " + myList);
Iterator i = myList.iterator();
System.out.println("Iterating over the elements in the AbstractList =" );
while (i.hasNext()) {
System.out.println(i.next());
}
}
}输出结果
Elements in the AbstractList = [75, 100, 150, 200, 250, 150, 150, 400] Iterating over the elements in the AbstractList = 75 100 150 200 250 150 150 400
