Write Java code for the following:
Create an Arraylist that can hold Integer objects.
Check and display whether the Arraylist is empty or not.
Add an element 50 into the Arraylist.
Add another element 60 in the position of 0 in the Arraylist.
Replace the element to 70 in index 1.
1. Declare an array to save 4 Dog objects. The Dog class is provided below. Look into the Dog class and find what attributes are needed for a dog object. Then initialize five dogs with the following information:
Lily, 5 years old
Jacob, 2 years old
Sugar, 8 years old
Bush, 3 years old
2. Print out every dog using a for loop (use either regular for loop or for-each loop, your choice). But you may find when you print out, the name and age are not displayed. Why?
3. Fix this problem by implementing the toString method in the Dog class.
Dog Class:
public class Dog { private String name; private int age;
public Dog(String name, int age) { this.name = name; this.age = age; } public void setName(String name) { this.name = name; }
}

- A programmer is designing a program to catalog all books in a library. He plans to have a Book class that stores features of each book: author, title, isOnShelf, and so on, with operations like getAuthor, getTitle, getShelf Info, and set Shelf Info. Another class, LibraryList, will store an array of Book objects. The LibraryList class will include operations such as listAll Books, addBook, removeBook, and searchForBook. The programmer plans to implement and test the Book class first, before implementing the LibraryList class. The program- mer's plan to write the Book class first is an example of (A) top-down development. (B) bottom-up development. (C) procedural abstraction. (D) information hiding. (E) a driver program.arrow_forwardjava Write a program to do the following: Create an ArrayList of Student. Add 7 elements to the ArrayList. Use for each loop to print all the elements of an ArrayList. Remove an element from an ArrayList using the index number. Remove the element from an ArrayList using the content (element name).arrow_forward1. Write a program that would resemble a power utility billing system. There will be an input window that would enter or input the meter number (5 numeric digits) and the present meter reading in kilowatt hours, the maximum would be 9999 kilowatts. A search from a 2d-arraylist would be made in order to get the previous meter reading of a particular meter number. The 2d- arraylist consists of meter number (5 numeric digits) and the previous meter reading in kilowatt hours (4 numeric digits with 9999 as maximum value). Provide at least 5 sample data or 5 rows with meter number and previous meter reading each row for the 2d-arraylist. When an input of meter number and present meter reading is made, search the 2d-arraylist for the equivalent meter number. If a match is found, get the kilowatt hour used (KWH) by subtracting the previous meter reading from the present meter reading. Note that if the present meter reading is less than previous meter reading, add 10000 first to the present…arrow_forward
- Java In this assignment, you will practice using an ArrayList. Your class will support a sample program that demonstrates some of the kinds of operations a windowing system must perform. Instead of windows, you will be manipulating “tiles.” A tile consists of a position (specified by the upper-left corner x and y), a width, a height, and color. Positions and distances are specified in terms of pixels, with the upper-left corner being (0, 0) and the x and y coordinate increasing as you move left and down, respectively. You won’t have to understand a lot about tiles and coordinates. That code has been written for you. You are writing a small part of the overall system that keeps track of the list of tiles. You are required to implement this using an ArrayList. The only method you need to use from the Tile class is the following: // returns true if the given (x, y) point falls inside this tile public boolean inside(int x, int y) Your class is to be called TileList and must…arrow_forwardStudent class is defined as follows.

- URGENtt!! You are asked to write a java class named "Kume". The UML class diagram of the Kume class is as follows. 3 The elements in the set are kept in an ArrayList. The constructor of the class takes an array of int and adds the elements of this array to the ArrayList named al. The add() method adds an integer it takes as a parameter to the get element. The delete() method deletes an Integer object that it takes as a parameter from the get element, returns true if it can be deleted, otherwise false. The print() function prints the elements of the set to the console. The compareTo() method is inherited from the Object class and is suppressed, and compares the get element of the Set object, which it takes as a parameter, with the retrieve element of the current set object in terms of content (the order of the elements is not important). It returns 1 if both sets contain the same elements, 0 otherwise. Below is a test code that creates two objects from the Kume class and performs…arrow_forwardImplement one of the sorts described in Chapters 15 and 16. Input is an array with at least 10 items. The items in the array can be of several types (Suggested types are integers-denoting how many customers visited the store in the last three weeks or strings-denoting the names of featured items). The items should be connected to a store in some way. Use some of the given data fields Print a title indicating what the data represents. Print the original data, AND the sorted data.arrow_forwardThis program is going to maintain a list of customers’ names and bank account balances. 1. Create a class called CustomerList with a main method that instantiates an ArrayList of String objects called customerName. Invoke the add method to add the following names into the ArrayList: Cathy Ben Jorge Wanda Freddie 1. Print each name in the ArrayList using a for a loop. 2. Create another ArrayList object called customerBalance, to save users’ balance. What is the type of this ArrayList? double or Double? You just need to declare this ArrayList and leave it empty for now. 3. For each customer, print the name and ask the user to enter the initial balance for this customer. Save the initial balance into ArrayList customerBalance. Use a loop to get this done for all 5 customers. The program should print out this for the first customer: Example: Please enter the account balance for Cathy: (waiting for user’s input …) Code: for(int i=0; i<5;i++) { Print(“Please enter the account balance…arrow_forward
