Java中的CopyOnWriteArrayList的iterator()方法
该iterator()方法用于返回此列表中元素的迭代器。
语法如下
Iterator<E> iterator()
要使用CopyOnWriteArrayList类，您需要导入以下包
import java.util.concurrent.CopyOnWriteArrayList;
以下是iterator()在Java中实现CopyOnWriteArrayList类方法的示例
示例
import java.util.Arrays;
import java.util.Iterator;
import java.util.concurrent.CopyOnWriteArrayList;
public class Demo {
public static void main(String[] args) {
CopyOnWriteArrayList<Integer>
arrList = new CopyOnWriteArrayList<Integer>();
arrList.add(50);
arrList.add(90);
arrList.add(150);
arrList.add(200);
arrList.add(350);
arrList.add(500);
arrList.add(650);
System.out.println("CopyOnWriteArrayList String Representation = " + arrList.toString());
Iterator i = arrList.iterator();
System.out.println("Iterating...");
while (i.hasNext()) {
System.out.println(i.next());
}
}
}输出结果
CopyOnWriteArrayList String Representation = [50, 90, 150, 200, 350, 500, 650] Iterating... 50 90 150 200 350 500 650
