Write a java program (class) named “TelevisionDemo”, that will use a class, “Television” that will allow a user to perform the following actions that will be performed by the second class: Turn on the TV. Turn off the TV. Increase the volume. Decrease the volume Find out the volume Find out the channel that is currently being used. (e.g. “int channel =4”, a value specified in the “Television” class) Use either scanner of JOPtionPane to ask the user what he wants to do. Use “if – else – if” statements to execute the method associated with user’s input of a number representing the desired action (e.g. 1=Turn on/Turn off TV, 2 = Increase volume, 3 = decrease volume, 4=find out channel). Use the choice to get value using the new Television object.

Write a Java class called BankAccount (Parts of the code is given below), which has two privatefields: name (String) and balance (double), and three methods: deposit(double amount),withdraw(double amount) and toString(). Write the necessary constructors, accessor methods andmutator methods. The deposit() method adds the amount to the account causing the current balanceto increase, withdraw() method subtracts the amount causing the current balance to decrease andtoString() method should return the name and the current balance separated by a comma. Forexample, if you print out the object with name Jake and balance 40.0 then it should print:Jake, $40.00public class BankAccount {private String name; ...public void deposit(double amount) {balance = balance + amount;}public void withdraw(double amount) {balance = balance – amount;}public BankAccount(){};public BankAccount(String name_new, double bal_new) {...}...}Write a client program called BankAccountClient that creates a BankAccount…
Use Java program to add a method printReceipt to the CashRegister class. Then create a driver class that asks the user to input the 5 items that they have bought recently and also the prices for each item, and print the items, their prices, and the total amount due. Hint: You will need to form a string of all prices. Use the concat method of the String class to add additional items to that string. To turn a price into a string, use the call String.valueOf(price). Also, the payment information will need to be the same as the price information. Here is the CashRegister class: /** A cash register totals up sales and computes change due.*/public class CashRegister{ private double purchase; private double payment; /** Constructs a cash register with no money in it. */ public CashRegister() { purchase = 0; payment = 0; } /** Records the sale of an item. @param amount the price of the item */ public void recordPurchase(double amount) {…

Write a Java program that has the following classes and capabilities: 1.0 Loanables The library has loanable items. A “loanable” is something that a person can borrow. A loanable item has these characteristics: A title A flag indicating the item is borrowed. A borrowed date. A due date. An ISBN is a unique number. A loanable can be borrowed, which sets the borrow date, due date, and flag. A loanable can be returned, which clears the flag. 2.0 Books There are two types of loanables: books and board games (referred to as just games). A book has the characteristic: number of pages. 3.0 Games A game has the characteristic: number of pieces. 4.0 Library A library consists of many books and games. There is a library user interface that lets one: add a book to the library. add a game to the library. search for a book or game by title and print info about the book/game. check out a book or game by specifying ISBN. return a book or game by specifying ISBN. There are rules about borrowing…
