Java question please Create a class called Account that has the following attributes: Account Client - AccountHolder Double - Balance Date - DateCreated Account() Account(Client AccountHolder, Double Balance) getAccountHolder() - Client setAccountHolder(Client) - void getBalance() - Double deposit(Double) - Double withdrawal(Double) - Double getDateCreated() - Date toString() - String compareTo(Account) - Integer equals(Account) - Double Notes: The account holder attribute will link to the Account class that you created in problem 6. Your constructor and overloaded constructor should set the date created to the current date. Your deposit method should add to the balance Your withdrawal method should remove from the balance, as long as there is enough money to withdrawal
In Java Program. Create a GeeCash class that has the following attribute: ○ Available balance in pesos ○ Transaction fee ○ Total amount sent The balance should start at 0. The transaction fee when sending money is fixed at Php 5.00. Your GeeCash should implement the following methods: ○void cashIn (double pesos) ○void sendMoney (double pesos) ○double getBalance() ○double getTotalAmountSent() ○void printSummary() When the printSummary is called, a report of the GeeCash instance should be printed. For example: Available balance : Php 537.00 Total Amount Sent : Php 1365.00 The peso amounts should be prefixed with “Php” and accurate to exactly two decimal places. Test your class by writing a GeeCashTester that will do the following: Create a GeeCash object called myGeeCash Cash in - Php 1000 Send money - 300 Cash in - 500 Send money - 250 Display available balance and total amount sent.
Which of the following statements is false? a. A class can contain only one constructor. b. An example of a behavior is the SetTime method in a Time class. c. An object created from a class is referred to as an instance of the class. d. An instance of a class is considered an object.
The Contact class implements the Comparable interface and thereforeprovides a definition of the compareTo method. In this case, the contacts aresorted by last name; if two contacts have the same last name, their first namesare used.
Below I have a sample class written in java and have several methods. I have only written the skeleton code for sample. Implement a simple proxy design pattern using java so that clients should only have access to very basic methods, while administrators of the system should have access to all methods public class Student { private name; private ID; private Grade; public double getname () {} public string getID () {} public double calculateGrade() {} }
Which of the following statements are correct about the given code snippet? class A: def __init__(self, i = 0): self.i = i class B(A): def __init__(self, j = 0): self.j = j def main(): b = B() print(b.i) print(b.j) Group of answer choices Class B inherits A, but the attribute “i” in A is not inherited. Class B inherits A, thus automatically inherits all attributes in A. When you create an object of B, you have to pass an argument such as B(5). The attribute “j” cannot be accessed by object b. How many except statements can a try-except block have? Group of answer choices zero one more than one more than zero
Write code for the InternetThing class to complete: a. A constructor that accepts a manufacturer and a serial number as its parameter. This constructor performs the following actions: i Store the serial number as a string ii Set a unique id number as an integer(hint- use the nextId). iii Set the IP address to the value “192.168.0.”+idnumber iv Set a local representation of a the power used in mW to the integer 1. v Set the password to “admin”. vi Prints the value “Created ”+ the result of the toString() method after assigning all instance data. vii Increment the number of things on record. b. Accessors for all private variables – Ensure the accessors for id, password and powerUse are named getId(), getPassword() and getPowerUse() c. A method setPassword that accepts a string argument and sets the instance password to the argument. All instance variables, except the password, should be private. The password should be protected.
