- Overloading is achieved when two or more methods in the same class have the samejava A constructor is a special method that has the same name as the class and the return type void. Choose one of the options:TrueFalseJava 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.
- Design a LandTract class that has two fields (i.e. instance variables): one for the tract’s length(a double), and one for the width (a double). The class should have: a constructor that accepts arguments for the two fields a method that returns the tract’s area(i.e. length * width) an equals method that accepts a LandTract object as an argument. If the argument object holds the same data (i.e. length and width) as the calling object, this method should return true. Otherwise, it should return false. a toString method (that returns a String representation of the tract’s length, width, and area). Demonstrate the class in a program by creating an array of three LandTract objects initialized with user input. Then, print the info of the LandTract objects stored in the array by invoking the toString method (implicitly or explicity). Also, use the equals method to compare at least two LandTract objects and print wether they are of equal size or not. Sample Output:…public class Cat { private int age; public Cat (int a) { age = а; } public int getAge() { return a; } } Which of the following best explains why the getAge method will NOT work as intended? The instance variable age should be returned instead of a, which is local to the constructor. The variable age is not declared inside the getAge method. The getAge method should be declared as private. The getAge method should have at least one parameter.write the definition of a class Counter containing: an instance variable named counter of type int a constructor that takes one int arguement and assigns its value to counter a method named increment that adds one to counter. it does not take parametes or return a value a method named decrement that subtracts one from counter. it does not take parameters or return a value a method named get_value of the instance variable counter write the definition of a class counter containing: an instance variable named counter of type int a constructor that assigns 0 to counter a method named increment that adds one to counter. it does not take parametes or return a value a method named decrement that subtracts one from counter. it does not take parameters or return a value a method named get_value of the instance variable counter using python

Procedure: 1. Develop a simple program for an individual savings account. Create two (2) classes named AmountDue (no class modifier) and RunAmountDue (public). 2. For the AmountDue class, create three (3) overloaded methods named computeAmountDue based on the following conditions: With a single parameter: It represents the price of one (1) item ordered. Add 12% tax and return the total due. With two (2) parameters: These represent the price of an item and the quantity ordered. Multiply the two (2) values, add 12% tax, and return the total due. With three (3) parameters: These represent the price of an item, the quantity ordered, and the discount amount. Multiply the quantity and price, deduct the discount amount, add 12% tax, and return the total due. 3. For the RunAmountDue class, import the Scanner class to be able to use the nextDouble() method. 4. Instantiate an AmountDue…Listen When a set of methods have the same name but different types/number of parameters in the same class, they are called: Overridden methods Overloaded methods Constructors toString() methods
- Crete a program that implements at least 4 combination of method overriding and overloading. Decide which class to use to properly illustrate your solution.These methods cannot be declared as abstract. Check all that is correct static methods constructor methods Osetters and getter Ovoid methods1. Complete the partial declaration of Class Car public class Car { declare three private instamce variables: color, speed, model / define a constructor with two parameters. C, m which will assign values to color and model. /define set and get method for all instance variables /define a method named calspeed() with int return type, the method will increase the speed by 50 mile per hour. 2. Complete the application below. public class CarApp { public static void main() { string color string model int speed %3D C2021;i %3D T08 //declare necessary object matching to the constructor definition 1/ display the color and model on the screen W call the calsneed) method and display the new speed after calculation.
