Solved in 2 steps
- 1. Write a Java program to create a new array list, add some colors (string) and print out the collection. The list should contain color "green". 2. Change the previous program to insert an element into the array list at the first position. Change the application to print out the index of color "green". Change the previous application to replace "green" value with "yellow". Change the previous application to remove the third element from the list. Change the application to sort the list of colors. Change the application to shuffle the list of colors. Change the application such that it swaps colors "Orange" and "Red". Change the application to close the current list into a new list. Change the application to trim the capacity of the initial array list to the current list size. Change the application to empty the second list. Change the application to test (print out a message) if the second list is empty. Change the application to increase the capacity of…1.

The program should allow users to add and delete subjects as well as update their calendars and to-do lists.
- Consider the interface below:import java.util.NoSuchElementException; public interface MyList<E> { public int getSize(); public void insert(E data) throws ListOverflowException; public E getElement(E data) throws NoSuchElementException; public boolean delete(E data); // returns false if the data is not deleted in the list public boolean search(E data); // returns index of data, else -1 is return}a. Use an array object to store the elements of the list object. The program should be able to show its size, get element, delete, and search from the array. b. This array object will have a fixed size of five (5) and that an attempt to insert an element into the array when full will result to a ListOverflowException.Consider the interface below:import java.util.NoSuchElementException; public interface MyList<E> { public int getSize(); public void insert(E data) throws ListOverflowException; public E getElement(E data) throws NoSuchElementException; public boolean delete(E data); // returns false if the data is not deleted in the list public boolean search(E data); // returns index of data, else -1 is return}a. Use an array object to store the elements of the list object. The program should be able to show its size, get element, delete, and search from the array. b. If the array is full and an element is to be inserted, a new array object with a size that is twice than the “old” array will be created. All the elements of the “old” array will be copied to the new array before inserting the new element.Write a simple phonebook program in oop c++. you are required to create a class named List with given functionalities.class List{int arr[50];int index;public:List();void add(int a);void remove(int a);void removeAt(int key);void addAt(int a, int index);void search(int a);void addAtStart(int a);void addAtLast(int a);void display();}; Note: Don't copy-paste.
