Use java programming language 1.1 Create a Student Object project. Create a Student class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The module mark is the average of the participation mark and the examination mark - calculate this using the calcModuleMark() method. The determineStNumber() method should compile a student number with the first 3 letters of the student's name, a '#' symbol, and a 3-digit randomly generated number (make use of a for-loop to concatenate these 3-digits). The stNumber data field should be set in the constructor by calling the determineStNumber() method. The toString() method must compile a string to display the student number, participation mark, examination mark, and module mark, formatted in table format. Student number PMark EMark MMark Mar#9186 81 64 72.00 1.2 Create a testStudents class. Do the following: -Write a static method called display() which receives…
Write a program in java that contain a class named office, data members include area and noOfEmployees. Two classes named regionalOffice and headQuarters are derived from office. regionalOffice contain managerName and location as data members while headQuarters contain CEO as data member. Data members of child class must be protected. Write input method, display method, a parametric constructor initializing all data members(both parent and child class). Use chaining in above all. Also define all accessor and mutator methods
public class Father { public String name; public int age; // customer name Father(){ name=”Hassan”; age=50;} public void display(){ System.out.println(“Name:”+name); System.out.println(“Age:”+age); } } 1. Based on Figure 3, create a class named Child that inherits the Father class. Declare an instance name location (String) for class Child. 2. Define a constructor in class Child and give an appropriate initial values for the instance (name, age, location). 3. Define a method display () in class Child, execute the display ( ) method in superclass using the keyword super. Method display ( ) in class Child should print the information of name, age and location 4. Create other class named Main for the main method and create 2 objects for the 2 classes (Father and Child). Then execute the display ( ) method for Father and Child. Example of the output as in Figure 4: Father's info: Name: Josh Age: 50 Child's info: Name: Christy Age: 20 Location:…
