30. True or False: The parameterized constructors of Java does not accept any parameters instead, using these constructors the instance variables of a method will be initialized with fixed values for all objects. False True Give an explanation for the answer. Thank you
Please write code in JAVA Step 1: An Account class stores a current balance, and provides getBalance, deposit, withdraw, and toString methods in addition to at least one constructor. Add an account class to the project.Step 2: A CheckingAccount class extends the Account class and has additional attribute overdraft limit and additional method chequeDeposit. Implement the CheckingAccount class in the project. Make sure you add a constructor to the class.Step 3: Override the toString method in the CheckingAccount class to add the overdraft limit as well to the returned string.Step 4: A SavingsAccount class extends the Account class and has additional attribute interest rate and a method named addInterest to calculate and add the interest to the account. Implement the SavingsAccount class in the project. Implement the SavingsAccount class in the project. Make sure you add a constructor to the class.Step 5: Add a test class named AccountTester to the project and implement a main method in…
1. Implement the following classes and interface in Java.• Shape interface which has the following methods:– public double perimeter(); // doesn’t have any parameters, returns the perimeter of the shape.– public double area(); // doesn’t have any parameters, returnsthe area of the shape.– public void info(); // doesn’t have any parameters, prints theperimeter and area of the shape.• Circle class that implements Shape interface and has a constructorthat takes the radius.• Rectangle class that implements the Shape interface and has a constructor that takes the width and height.• Square class that extends the Rectangle class and has a constructorthat takes the edge length.– Square constructor should only call the super constructor withcorrect parameters.– Square constructor should not explicitly implement the Shapeclass, but it should inherit the perimeter, area and info methodsfrom the Rectangle class.2. Create a Test class, and create one Circle, one Rectangle and one Squareobjects.…
Subtasks: 1. Create a Doll class. 2. Create the required constructor. 3. Write a method to print the name and the price of the object 4. Use operator overloading for the addition operators. 5. Write a method to handle operator overloading for the ">" logical operator that compares the price of the objects. Hints: Notice that the price of each object is being checked with the price of obj in the given code. • Notice the word Doll in the first 4 outputs and the last output. You have to print exactly as represented here. Task 8 Design a class called Coordinates with an appropriate constructor. Then perform the subtraction, multiplication and equality check operations in the given code using operator overloading. Sample Input 1: 1 #Write your code here #Do not change the following lines of code 3 2 p1 = Coordinates(int(input()),int(input())) p2 = Coordinates(int(input()),int(input())) 4 %D Sample Output 1: (-2,-2) (3,8) The calculated coordinates are NOT the same. p4 = p1 - p2…

Create a Java class called "Person" with the following instance variables: a String variable named "name" an integer variable named "age" Create a constructor for the Person class that takes in a String parameter "name" and an integer parameter "age" and initializes the instance variables with those values. Create a method in the Person class called "introduce" that returns a String introducing the person, including their name and age. In the main method, create a new instance of the Person class and pass in the values "John" and 30 for the name and age parameters, respectively. Then, call the "introduce" method on the new instance and output the result to the console. Output: "Hi, my name is John and I am 30 years old." Finally, create another instance of the Person class with a different name and age, and call the "introduce" method on that instance as well. Output: "Hi, my name is Jane and I am 25 years old."
Java Programming: Write a static method named urgentAndIncomplete. Write the method as if it is in Main.java (not part of the ToDoItem class). The method should: Accept three ToDoItem references as parameters, and Return an int. Count how many of the ToDoItems meet two criteria: A priority greater than 3 Not completed The method should return how many of the parameters meet these criteria. That will be either 0, 1, 2, or 3.
For Java Programming: Write a class encapsulating the concept of a course grade, assuming a course grade has the following attributes: a course name and a letter grade. Include a constructor, the accessors and mutators, and methods toString and equals. Write a client class to test all the methods in your class.
