Java中AbstractSequentialList的contains()方法
contains()AbstractSequentialList的在Java方法被用来检查一个元素是否在Collection。
语法如下
public boolean contains(Object ob)
在这里，ob是要检查的元素。要使用Java中的AbstractSequentialList类，您需要导入以下包
import java.util.AbstractSequentialList;
以下是contains()在Java中实现AbstractSequentialList方法的示例
示例
import java.util.LinkedList;
import java.util.AbstractSequentialList;
public class Demo {
public static void main(String[] args) {
AbstractSequentialList<Integer> absSequential = new LinkedList<>();
absSequential.add(250);
absSequential.add(320);
absSequential.add(400);
absSequential.add(550);
absSequential.add(600);
absSequential.add(700);
absSequential.add(900);
System.out.println("Elements in the AbstractSequentialList = "+absSequential);
System.out.println("Does the element exist? = " + absSequential.contains(400));
}
}输出结果
Elements in the AbstractSequentialList = [250, 320, 400, 550, 600, 700, 900] Does the element exist? = true
