Java Collections Linked List | removing an object vs element using .remove() method

  LinkedList arr = new LinkedList<>();
    arr.add(2);
    arr.add("Anam");
    arr.add(1);
    System.out.println(arr);
    arr.remove(2);
    arr.remove("Anam");
    System.out.println(arr);

This is a LinkedList of 3 elements of mixed data types(int and String).
I want to use .remove() method to remove using an object name not index.
So how do I remove element 2(at index 1) without using the index, but using the object(element) name via .remove(object) method.

I am using Intellij and after many trials i cannot perform this.

P.S: Every time I try to use .remove(object), it automatically infers an index value.
How to use .remove to remove an integer value, by using Integer object as .remove() method argument. I don’t want to use index in .remove()

>Solution :

Lists in java have the methods remove(Object o) and remove(int index). When you use .remove(2), the 2 is recognized as a primitive int. To use the Object Integer, you need to pass the parameter like this:

    arr.remove(Integer.valueOf(2));

or like this:

    arr.remove((Object) 2);

This casts the primitive int into the object Integer, which then calls remove(Object o) instead of remove(int index).
