Java中的CopyOnWriteArrayList的toArray()方法
该toArray()方法用于按正确顺序返回包含此列表中所有元素的数组。
语法如下-
Object[] toArray()
要使用CopyOnWriteArrayList类，您需要导入以下包-
import java.util.concurrent.CopyOnWriteArrayList;
以下是toArray()在Java-中实现CopyOnWriteArrayList类方法的示例
示例
import java.util.Arrays;
import java.util.concurrent.CopyOnWriteArrayList;
public class Demo {
public static void main(String[] args) {
CopyOnWriteArrayList<Integer> arrList = new CopyOnWriteArrayList<Integer>();
arrList.add(220);
arrList.add(250);
arrList.add(400);
arrList.add(500);
arrList.add(650);
arrList.add(700);
arrList.add(800);
System.out.println("CopyOnWriteArrayList String Representation = " + arrList.toString());
Object[] myArr = arrList.toArray();
System.out.println("Array = "+Arrays.toString(myArr));
}
}输出结果
CopyOnWriteArrayList String Representation = [220, 250, 400, 500, 650, 700, 800] Array = [220, 250, 400, 500, 650, 700, 800]
