Step by step
Solved in 2 steps
- What are wrapper classes and why are they useful for ArrayLists? Include examples of autoboxing and unboxing. Word count: More than 300 words and less than 700 words.How can the effectiveness of an ArrayList be evaluated?How can you evaluate the state of an ArrayList to assess how effectively it is functioning?
- How can an ArrayList be used?Java ArrayLists can only be filled with reference type data, so you cannot fill them with primitive type data. How can you work around this with integers? (How can you have an ArrayList filled with integers?)Explain the fundamental difference between an array and an arraylist.
- Design and implement a Java class named Book with two data members: title and price. The class should have suitable constructors, get/set methods, and the toString method. Design and implement another Java class named BookShelf which has an ArrayList data member named bookList to store books. The class should have suitable constructors, get/set methods, and the toString method, as well as methods for people to add a book (prototype: addBook(Book book)), remove a book (prototype: removeBook(Book book)), and search for a book (prototype: findBook(Book book)). Test the two classes by creating a Bookshelf object and five Book objects. Add the books to the bookshelf. Display the contents of the bookshelf. Test the removeBook and findBook methods as well. Take screenshots of your tests and submit them with your Java code (not the whole project)1. What is the syntax for creating a Java array and and an ArrayList? 2. Briefly explain how generics make ArrayList flexible. 3. What are some of the differences between arrays and ArrayLists?EclipseIDE - Java Programming assigment For your program: Create a data class named Automobile that implements the Comparable interface. Give the class data fields for make, model, year, and price. Then add a constructor, all getters, a toString method that shows all attribute values, and implement Comparable by using the year as the criterion for comparing instances. Write a program named TestAutos that creates an ArrayList of five or six Automobiles. Use a for loop to display the elements in the ArrayList. Sort the Arraylist of autos by year with Collections.sort(). Finally, use a foreach loop to display the ArrayList sorted by year.
