Java中的CopyOnWriteArrayList方法的clone()方法
要返回CopyOnWriteArrayList的浅拷贝，请使用clone()方法。
语法如下：
public Object clone()
要使用CopyOnWriteArrayList类，您需要导入以下程序包：
import java.util.concurrent.CopyOnWriteArrayList;
以下是clone()在Java中实现CopyOnWriteArrayList类方法的示例：
示例
import java.util.concurrent.CopyOnWriteArrayList;
public class Demo {
public static void main(String[] args) {
CopyOnWriteArrayList<Integer> arrList = new CopyOnWriteArrayList<Integer>();
arrList.add(30);
arrList.add(90);
arrList.add(80);
arrList.add(70);
arrList.add(90);
arrList.add(100);
arrList.add(120);
System.out.println("CopyOnWriteArrayList = " + arrList);
System.out.println("Cloned CopyOnWriteArrayList = " + arrList.clone());
}
}输出结果
CopyOnWriteArrayList = [30, 90, 80, 70, 90, 100, 120] Cloned CopyOnWriteArrayList = [30, 90, 80, 70, 90, 100, 120]
