Quadra Kill Objective: At the end of the activity, the students should be able Override methods in a superclass to. Software Requirements: Latest version of NetBeans IDE Java Development Kit (JDK) 8 . Procedure: Part 1 (Week 15) 1. Create a class named RunQuad. This class shall contain the main method. 2. Add three (3) classes named Quadrilateral, Rectangle, and Square. Rectangle shall inherit from Quadrilateral while Square shall inherit from Rectangle. 3. Declare a public method named showDescription() in all three (3) classes except in RunSquad. Customize each method by creating different println() statements. For Quadrilateralis quadrilateral". b. For Rectangle: " has 4 right angles'. Add a super() statement to call Quadrilateral's method. C. For Square: *- has 4 equal sides". Add a super() statement to call Rectangle's method. 4. Code the main method of the RunQuad class. The output shall ask the user to press Ror S to choose between rectangle and square. Display appropriate description(s). 5. Keep a copy of your program. You will be using it next week. a Sample Output: Press R for Rectangle or s for Square. S A square: - has 4 equal sides - has 4 right angles is quadrilateral a. Part 2 (Week 16) 6. Add three (3) more classes named Parallelogram, Rhombus, and Trapezoid. Parallelogram shall inherit from Quadrilateral and shall be the new parent class of Rectangle. Its println() statement shall be - has 2 pairs of parallel sides". b. Rhombus shall inherit from Parallelogram. Its println() statement shall be "- has 4 congruent sides". C. Trapezoid shall inherit from Quadrilateral. Its println() statement shall be " has 1 pair of parallel sides 7. Modify the main method of the RunQuad class. The choices will now be R, S, P, H, and T. Display appropriate description(s). 09 Hands-on Activity 1 *Property of STI Page 1 of 2 STI IT1908 Sample Output: Select from the following: R - Rectangle s Square P - Parallelogram H - Rhombus T - Trapezoid H A rhombus: has 4 congruent sides
