Q2. Write a program that creates a class named BankAccount and contains: • Private attributes: • • ° ° id int), balance double and annual InterestRate (double). These attributes must never take a negative value. beneficiaries String [] ) to store the names of people who may receive the balance of funds when the account owner passes away. count static int ) to keep a record of the number of created objects. Constructors: 。 A 3-argument constructor that creates an account with given annual InterestRate), balance, and list of beneficiaries passed to the constructor as a series of names, e.g. BankAccount(3300, 6.7, "John", "Lili"). The constructor must increment count by 1, and then stores the new count into id. 。 A no-argument constructor that invokes the above 3-arg constructor and sets both balance and annual Interest Rate to 0, and beneficiaries to a new empty (String array of the size 3. Methods: ° Getter methods for all attributes. ° Setter methods for balance, annual Interest Rate °…

Q1. Create a class named Cuboid to represent cuboid objects and contains: • Three double attributes ①, W, and ʼn specifying the length, width and height of the cuboid. • A String attribute colour that specifies the colour of the cuboid. • A constructor (with 4 arguments) that creates a cuboid with specified values. • A constructor (with no arguments) that sets 1, w, and h to 1 and color to "white". This constructor should invoke the 4-argument constructor using the this keyword. • Your program must have these methods: 。 Getter methods for all fields (e.g. getColour () which returns the colour) о о getVolume: returns the cuboid volume which is 1*w*h getSurfaceArea(): returns the surface area of the cuboid: (2*(1*w + 1*h + w*h) displayInfo(): displays on the screen the colour, dimensions, surface area, and volume of this cuboid. Write a test program that creates two objects of the Cuboid class ⚫ the first object will have default values ⚫ the second object must be green of length = 8,…
