Given the following class scenarios write the statements to define the default constructor for the class
A BudgetItem class with the following instance variables:
* expenseName - default value "unknown"
* expenseAmount - default value 0
Is this answer correct below for the following statement
Answer - public BudgetItem()
{
this .expenseName = "unknown"
this.expenseAmount = 0;
}
public BudgetItem(){
this .expenseName = "unknown"
this.expenseAmount = 0;
}
The above answer is perfectly alright
Please find another version
public BudgetItem(){
expenseName = "unknown"
expenseAmount = 0;
}

Check all statements that are true regarding constructors in Java 1. A default empty constructor will be generated if you don't provide any. This default constructor calls super() and initializes all instance variables to default value like 0, null. 2. Constructor name should be the exact same same name as the class name 3. A class can only have one or more constructors 4. It is not required to explicitly define a constructor 5. A class can only have one...
Can you tell me if this code is correct A shoppingCart class with the following instance variables: * cardNumber - default value "unknown" * securityCode - default value "000" Here is my answer for the following above public ShoppingCart() { this.cardNumber = "unknown"; this.securityCode = 000; }
Which of the following statements are true? A default constructor is provided automatically if no constructors are explicitly declared in the class. At least one constructor must always be defined explicitly. Every class has a default constructor. The default constructor is an arg constructor.
also write accessor and mutator methods for the class. please
Given the CarRecord class definition below define the following: 1) A default constructor that initializes yearMade to 2006 and vehicleldNum to 1000. 2) An overloaded constructor that initializes yearMade and vehicleldNum to values passed as parameters. public class CarRecord { private int yearMade; private int vehicleldNum; }

Create a BoxFigure class that inherits RectangleFigure class BoxFigure Class should contain:- Height instance field- Default constructor -- that calls the default super class constructor and sets the default height to 0- Overloaded constructor with three parameters (length, width and height) – that calls the two parameterized super class constructor passing in length and width passed and sets the height to passed height.- setDimension method with three parameters (length, width, height) – call the super class setDimension and pass in...
