从LinkedList中移除指定元素

import java.util.LinkedList;

public class RemoveSpecifiedElement {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        LinkedList lList = new LinkedList();
        lList.add("1");
        lList.add("2");
        lList.add("3");
        lList.add("4");
        lList.add("5");
     
        System.out.println("LinkedList contains : " + lList);
        boolean isRemoved = lList.remove("2");
        System.out.println("Is 2 removed from LinkedList ? :" + isRemoved);
        System.out.println("LinkedList now contains : " + lList);
       
        Object obj = lList.remove(2);
        System.out.println(obj + " has been removed from LinkedList");
        System.out.println("LinkedList now contains : " + lList);

    }

}
Console:
LinkedList contains : [1, 2, 3, 4, 5]
Is 2 removed from LinkedList ? :true
LinkedList now contains : [1, 3, 4, 5]
4 has been removed from LinkedList
LinkedList now contains : [1, 3, 5]
