Description: For more course tutorials visit www.tutorialrank.com General Instructions Exercises 1, 2, 4, and 5 use the programs in DocSharinglabeled “User-defined classes." Exercises 7 and 8 use the programs in DocSharinglabeled “Using interfaces." Exercise 1: Review of classes Create a project using the classes in the DocSharing area labeled “User-defined classes." Compile it, run it, and review the code that is given carefully. Exercise 2: User-defined methods The function area of the Triangle class is the framework of the actual method. Modify it so that it calculates the area of the triangle. Write a Main class to test your area method. Note: to calculate the area of a triangle from the vertices, first find the distances between each pair of vertices to obtain the length of the sides of the triangle. Then apply Heron’s formula to calculate the area given the length of the sides. – PowerPoint PPT presentation
