Program Plan Intro

Program Plan:

  • Include the required import statement.
  • Define the main class.
    • Define the main method using public static main.
      • Create the objects for the class “Course”.
      • Add the students name to the class objects “course1” and “course2”.
      • Display the output.
      • Declare and set the string array.
      • The “for” condition is used to get the number of students.
  • Define the “Course” class.
    • Declare the required variables and array list.
    • Define the constructor for the class.
    • Define the “addStudent” method and add the values to the list.
    • Define the “getStudents” method and create an object for string array.
      • Add the values to the array.
      • Return the result.
    • The “getNumberOfStudents ()” method will return the size.
    • The “getCourseName ()” method will return the course name.
    • The “dropStudent ()” method will remove the student in the list.

Explain encapsulation briefly
(Triangle class) Design a new Triangle class that extends the abstract GeometricObject class. Draw the UML diagram for the classes Triangle and GeometricObject and then implement the Triangle class. Write a test program that prompts the user to enter three sides of the triangle, a colour, and a Boolean value to indicate whether the triangle is filled. The program should create a Triangle object with these sides and set the colour and filled properties using the input. The program should display the area, perimeter, colour, and true or false to indicate whether it is filled or not.
