Thank you!java code Problem : Bank Account Details Super Class : Account Attributes : customerid , customerame , balance , account Methods : 1-Read the account details 2-Display the Account details Sub class : Bank Attributes : deposit amount , withdraw the amount Methods : 1-Set the deposit amount and return the deposit amount 2-Set the withdraw amount and return the withdraw the amount 4- Display the Bank detailsWrite a code in Java programming You are working in a game company that is developing a new RPG game. One of the core features of the game is the ability to create and manage different types of characters, such as warriors, mages, and archers. However, your colleague, who was previously working on the implementation of the CharacterManager class, has been laid off due to excessive absences. You have been assigned to take over the project and complete the implementation of the class based on the design specifications outlined below: Given the following main method: public static void main(String[] args) { CharacterManager manager = CharacterManager.getInstance(); manager.createCharacter(CharacterType.WARRIOR).attack(); manager.createCharacter(CharacterType.MAGE).attack(); manager.createCharacter(CharacterType.ARCHER).attack(); } Your output should be: Warrior is attacking Mage is attacking Archer is attacking Note that you should not change the method signature.

(A) Writing a program from top to bottom in Java (B) Writing an essay describing how the program will work, without including any Java code (C) Using driver programs to test all methods in the order that they're called in the program (D) Writing and testing the lowest level methods first and then combining them to form appropriate abstract operations (E) Writing the program in terms of the operations to be performed and then refining these operations by adding more detailJava program: 1. Create a class named Rectangle that has instance variables height and width. Provide a constructor that initializes the instance variables based on parameter values, getter and setter methods for the instance variables, a toString method, and a method named computeSurfaceArea(), that returns the surface area of the rectangle. 2. Create a child class named RectPrism that contains an additional instance variable named depth. Provide a constructor, getter and setter methods for the new instance variable, and a method named computeVolume(), that returns the volume of the rectangular prism. Override the toString() and the computeSurfaceArea() methods. 3. Write an application called Demo, that instantiates a rectangle and a rectangular prism, and tests all the methods. Make sure you indent and comment your code based on the examples in the textbook. Don’t forget to include your name, the course number, title of the assignment, and today’s date.
