In your definition for the Withdraw method, check if the account has sufficient funds before making a withdrawal. Apply transaction fees as per the table above:Find the error(s) in the following code snippet and explain how to correct it (them): 1 class Example { 2 public: Example(int y = 3 10) : data (y) {} 4 int getIncrementedData() const { return ++data; 7 } 8. 9 private: 10 int data; 11 };
- Method Overloading is a feature that allows a class to have two or more methods having same name, if their argument lists are different. Argument lists could differ in: 1. Number of parameters. 2. Data type of parameters. 3. Sequence of Data type of parameters. Write different version of method sum() that display the sum of the values received as parameter according to the following main method content: public static void main(String[] args) { sum ( 10, 10 ); sum ( 10, 10, 10 ); sum ( 10.0, 10.0 ); sum ( 10, 10.0 ); sum ( 10.0, 10); } You have to define five functions with the specified types. Then, demonstrate the Argument Promotion concept by reducing the number of method to two.Design a class that holds the following personal data: name, address, age, and phone number. Write appropriate accessor and mutator methods. Also, write a program that creates three instances of the class. One instance should hold your information, and the other two should hold your friends’ or family members’ information.Problem: Construct a program that simulates the major Bank Transactions: Deposit, Withdraw and Inquire. Your program should use methods for the 3 transactions and another method for the login transaction. Below is the initial structure of the your code: public class BankTransaction { static void DisplayMenu() { /*this method displays the menu of the transactions*/ } static void withdraw(float amount) { /*this method should deduct the amount withdrawn from the current balance*/ } static void deposit(float amount) { /*this method should add the amount deposited to the current balance*/ } static float inquire() { /*this method should return the current balance*/ } static boolean CorrectPinNUmber() { /*this method should ask user to input the pin number. returns TRUE if the pin number is valid*/ It } public static void main(String a[]) { } } Design your main program to test these methods. You can design your own user interface.
- Java Programming problem Create a checking account class with three attributes: account number, owner’s name, and balance. Create constructor, getters and setters. If one is to set the initial balance of an account as a negative value in a setter or a constructor, remind the user about the error and set it as 0. Create a CheckingAccountDemo class, and create a main method in which Ask for the name, account number, and initial balance for one account from the keyboard input. With these input values as arguments in a call to the constructor, create a CheckingAccount object. Print the summary of this account that includes information on the name, account number, and balance by calling the getters.//Todo write test cases for SimpleCalculator Class // No need to implement the actual Calculator class just write Test cases as per TDD. // you need to just write test cases no mocking // test should cover all methods from calculator and all scenarios, so a minimum of 5 test // 1 for add, 1 for subtract, 1 for multiply, 2 for divide (1 for normal division, 1 for division by 0) // make sure all these test cases fail public class CalculatorTest { //Declare variable here private Calculator calculator; //Add before each here //write test cases here }Note: This is a Java program question.
