Concept explainers
The following class displays a disclaimer every time an instance is created using the default constructor. However, we would like the disclaimer to appear only once when the very first Vehicle object is created. Any future Vehicle objects that are created should display no disclaimer. Modify the code to use a static boolean variable that is initialized to false when it is defined. Once the disclaimer is displayed the variable should be set to true, and an if statement added around the display so the disclaimer is only output if the variable has the value false. This should force the
public class Vehicle
{
public Vehicle()
{
System.out.println (“You should not operate this vehicle under the”);
System.out.println(“influence of alcohol!”);
}
}

- O Challenge task Write the code of the Constructors and Distructor for the following class 1-Write the code for the empty constructor, that sets X, Y to 0, and prints "Constructor 1 2-Write the code for the parameterized constructor, that takes two integers AB and assigns X A Y=B. and prints the Sentance "Constructor 2 3-Write the code for the Distructor that prints the Sentance "Distruct" followed by the value of X, Y Constraints 5 Input Format the input is two integers E. Output Format as shown in Test case Sample #1 Input 57 Output Constructor 1 Constructor 2 Constructor 1 Destruct 0,0 Destruct 5,7 Destruct 0,0arrow_forwardPYTHON: Define the Artist class with a constructor to initialize an artist's information and a print_info() method. The constructor should by default initialize the artist's name to "None" and the years of birth and death to 0. print_info() should display Artist Name, born XXXX if the year of death is -1 or Artist Name (XXXX-YYYY) otherwise. Define the Artwork class with a constructor to initialize an artwork's information and a print_info() method. The constructor should by default initialize the title to "None", the year created to 0, and the artist to use the Artist default constructor parameter values. Ex: If the input is: Pablo Picasso 1881 1973 Three Musicians 1921 the output is: Artist: Pablo Picasso (1881-1973) Title: Three Musicians, 1921 If the input is: Brice Marden 1938 -1 Distant Muses 2000 the output is: Artist: Brice Marden, born 1938 Title: Distant Muses, 2000 I have the code but I am getting errors that I can't seem to get rid of any suggestions would be appreciatedarrow_forwardUsing the dialog boxes in the JOptionPane class, write a program that calculates and prints themonthly paycheck for an employee.

- It is possible for a class to have more than one constructor.A) This is correct. B) The answer is False.arrow_forwardPlease help me with this Java chapter 6 programming challenge. Thank youarrow_forwardProblem Class In this exercise, you are going to create the Problem class. The Problem class is used to help simulate a math fact, for example: 2 + 5 = Your class needs to contain two contructors, one that takes String, int, int that represts the operator sign(+, -, *, or /), the minimum, and maximum values for the number range, and a second constructor that takes only a String that represents the operator sign. For the second constructor, the minimum should default to zero and the maximum to ten. Your Problem object should generate 2 random integers between the minimum and maximum values (inclusively). Each Problem object should only have one set of numbers that do not change. While you may include additional helper methods, two methods need to be available to the user. The first is the answer method that should return a double that represents the answer to the problem. The second is the toString that should return a String that represents the problem. The format should be: number…arrow_forward
- The Essay class has a default constructor, a constructor with two parameters, and a constructor with three parameters. Declare the following objects: essay1 with no arguments essay2 with essayTitle and essayAuthor as arguments essay3 with essayTitle, essayAuthor, and essayYear as arguments Ex: If the input is Painting Cole 1919, then the output is: Essay: Undefined, Unspecified, 0 Essay: Painting, Cole, 0 Essay: Painting, Cole, 1919 Archive.java public class Archive { publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); StringessayTitle; StringessayAuthor; intessayYear; essayTitle=scnr.next(); essayAuthor=scnr.next(); essayYear=scnr.nextInt(); /* Your code goes here */ essay1.print(); essay2.print(); essay3.print(); } } Essay.java public class Essay { private String title; private String author; private int year; public Essay() { // Default constructor title = "Undefined"; author = "Unspecified"; year = 0; }…arrow_forwardDesign a class called Date that has integer data members to store month , day, and year. The class should have two constructors; a default constructor that accepts no parameters, and a three-parameter constructor that allows the date to be set by the programmer. If the user creates a Date object without passing any arguments, or if any of the values passed are invalid, the default values of 1, 1, 2001 (i.e., January 1, 2001) should be used. The class should have three (3) member functions to print the date in the following formats: 3/15/16 March 15, 2016 15 March 2016 Demonstrate the class by writing a program that uses it. Be sure your program only accepts reasonable values for month and day. The month should be between 1 and 12. The day should be between 1 and the number of days in the selected month. I expect to see all uses of the constructors that you made, including the error checking. I also expect to see all uses of the 3 output functions in your program. You are responsible…arrow_forwardHelp me With this Java Taskarrow_forward
- Object Oriented Programming in JAVA Define and use a class for the student record. The class should have instance variables for the quizzes, midterm, final, overall numeric score for the course, and final letter grade. The overall numeric score is a number in the range 0 to 100, which represents the weighted average of the student’s work. The class should have methods to compute the overall numeric grade and the final letter grade. These last methods should be void methods that set the appropriate instance variables. Your class should have a reasonable set of accessor and mutator methods, an equals method, and a toString method.arrow_forwardThe reference this can be used to refer to an object or to invoke another constructor of the same class.
