public class RemoveElementsFromLinkedListExample {
    public static void main(String[] args) {
        LinkedList<String> fruitList = new LinkedList<>();


        System.out.println("Initial LinkedList = " + fruitList);

        // Remove the first element in the LinkedList
        String element = fruitList.removeFirst();  
        System.out.println("Removed the first element "
            + element + " => " + fruitList);

        // Remove the last element in the LinkedList
        element = fruitList.removeLast();   
        System.out.println("Removed the last element " 
          + element + " => " + fruitList);
        // Remove the first occurrence of the specified element from the LinkedList
        boolean isRemoved = fruitList.remove("banana");
        if(isRemoved) {
         System.out.println("Removed banana => " + fruitList);
        // Removes all of the elements of this collection that 
        // satisfy the given predicate.
        fruitList.removeIf(programmingLanguage -> programmingLanguage.startsWith("C"));
        System.out.println("Removed elements starting with C => " + fruitList);
        //Removes all of the elements from this list. 
        // The list will be empty after this call returns.
        System.out.println("Cleared the LinkedList => " + fruitList);
Initial LinkedList = [Apple, banana, mango, Pinaple]
Removed the first element Apple => [banana, mango, Pinaple]
Removed the last element Pinaple => [banana, mango]
Removed banana => [mango]
Removed elements starting with C => [mango]
Cleared the LinkedList => []
