Program Plan Intro
Iterator:
Iterator is used to access data in the collections without relieving how data stored in the data structure.
Iterator interface has the iterator() method, which returns iterator object. Iterator method is used for traversing data in an orderly fashioned manner.
Data in the collections can be accessed using the following three methods,
- next() – Accessing the next elements in the iterator.
- hasNext() – To check more elements are available in the iterator.
- remove() – To delete the last element returned by the iterator.

- Duplicate Set This function will receive a list of elements with duplicate elements. It should add all of the duplicate elements to a set and return the set containing the duplicate elements. A duplicate element is an element found more than one time in the specified list. The order of the set does not matter. Signature: public static HashSet<Object> duplicateSet(ArrayList<Object> list) Example: INPUT: [2, 4, 5, 3, 3, 5] OUTPUT: {5, 3}arrow_forwardApart from the main list in the list above, elements with the same value are also linked. According to this; a) Write the Generic Node class. b) Write the method that adds a new element to the end of the list.arrow_forwardCreate code that will find duplicate keys in a linked list and remove them all.arrow_forward
- Write a method void removeShortStrings(HashSet<String> set). The method should remove from the set any string that is shorter than 100.arrow_forwardA feature of our Set ADT is that it is a collection that allows duplicate elements.arrow_forwardAssuming the node class has already been created, start your code from the method: def swapReplaceMidOdd(head, element): #write your code herearrow_forward
- Write an equals method for the LBList class. Return true if the lists have the same number of elements and the elements in each position of the lists are the same; otherwise return false. DO NOT USE ANY OTHER METHODS OF THE LBLIST CLASS.arrow_forwardI get an error at the followinf code.. it says >= is undefined for the argument type. // Return the maximum subarray among the left, right, and cross subarrays if (left.getLast() >= right.getLast() && left.getLast() >= cross.getLast()) { returnleft; } else if (right.getLast() >= left.getLast() && right.getLast() >= cross.getLast()) { returnright; } else { returncross; }arrow_forwardYou should create a method and call it findTotalleaves (); this method will find all of the nodes that are considered to be leaves, which are nodes that do not have any BNode dependents. The public function must not take any arguments, but the private method must accept as a parameter a BNode that represents the current root.arrow_forward
- Write a for-each loop that calls the addInterest method on each BankAccount object in a collection called accounts. What is required for that loop to work?arrow_forwardThe for loop iterates across the elements in a given list. So long as there are objects to process, it will keep going. In what way does this statement hold true or false?arrow_forwardApart from the main list in the list above, elements with the same value are also linked. According to this; a) Write the Generic Node class. b) Write the method that adds a new element to the end of the list. JAVA CODEarrow_forward
