Im trying to get the program to out put this information
// ===== Code from file Person.java =====
public class Person {
private int ageYears;
private String lastName;
public void setName(String userName) {
lastName = userName;
}
public void setAge(int numYears) {
ageYears = numYears;
}
// Other parts omitted
public void printAll() {
System.out.print("Name: " + lastName);
System.out.print(", Age: " + ageYears);
}
}
// ===== end =====
// ===== Code from file Student.java =====
public class Student extends Person {
private int idNum;
public void setID(int studentId) {
idNum = studentId;
}
public int getID() {
return idNum;
}
}
// ===== end =====
// ===== Code from file StudentDerivationFromPerson.java =====
public class StudentDerivationFromPerson {
public static void main(String[] args) {
Student courseStudent = new Student();
/* Your solution goes here */
//Person a = new Person();
courseStudent.setName("Smith");
courseStudent.setAge(20);
courseStudent.setID(9999);
courseStudent.printAll();
System.out.print(",ID: "+ getID());
}
}

- Program - Python Make a class.The most important thing is to write a simple class, create TWO different instances, and then be able to do something. For example, create a pizza instance for Suzie, ask her for the toppings from the choices, and store her pizza order. Then create a second pizza instance for Larry, ask for his toppings and store his pizza order. Then print both of their orders back out. You do not need to make your class very complicated. (Shouldn't be the pizza example but something similar)arrow_forwardIn python and include doctring: First, write a class named Movie that has four data members: title, genre, director, and year. It should have: an init method that takes as arguments the title, genre, director, and year (in that order) and assigns them to the data members. The year is an integer and the others are strings. get methods for each of the data members (get_title, get_genre, get_director, and get_year). Next write a class named StreamingService that has two data members: name and catalog. the catalog is a dictionary of Movies, with the titles as the keys and the Movie objects as the corresponding values (you can assume there aren't any Movies with the same title). The StreamingService class should have: an init method that takes the name as an argument, and assigns it to the name data member. The catalog data member should be initialized to an empty dictionary. get methods for each of the data members (get_name and get_catalog). a method named add_movie that takes a Movie...arrow_forwardAnalyze the following code. public class Test { public static void main(String[] args){ System.out.printlin( m(2) ); public static int m( int num ) { return num; } public static void m( int num ) { System.out.printin( num ); } The program has a compile error because the second m method is def method. The program runs and prints 2 once.arrow_forward
- 8) Now use the Rectangle class to complete the following tasks: - Create another object of the Rectangle class named box2 with a width of 100 and height of 50. Note that we are not specifying the x and y position for this Rectangle object. Hint: look at the different constructors) Display the properties of box2 (same as step 7 above). - Call the proper method to move box1 to a new location with x of 20, and y of 20. Call the proper method to change box2's dimension to have a width of 50 and a height of 30. Display the properties of box1 and box2. - Call the proper method to find the smallest intersection of box1 and box2 and store it in reference variable box3. - Calculate and display the area of box3. Hint: call proper methods to get the values of width and height of box3 before calculating the area. Display the properties of box3. 9) Sample output of the program is as follow: Output - 1213 Module2 (run) x run: box1: java.awt.

Assume userValue is greater than 1000 and less than 99999. Assign tensDigit with userValue's tens place value.
