Write a program to calculate area of Circle by using getArea(int radius) method which is inherited from Shape and print the value by invoking that method from TestCircle class. Draw class diagrams for Shape,Circle and TestCircle.

Write a program to calculate area of Rectangle by using getArea(int length,int width) method which is inherited from Shape and print the value by invoking that method from TestRectangle class. Draw class diagrams for Shape, Rectangle and TestRectangle.

Write a program to calculate area of Square by using getArea(int length) method which is inherited from Shape and print the value by invoking that method from TestSquare class. Draw class diagrams for Shape, Square and TestSquare.

Write a program to calculate the distance how much Kangaroo jumps by using jumping(double distance) method which is extended from Animal and print the value by invoking that method from TestKangaroo class. Draw class diagrams for Animal,Kangaroo and TestKangaroo.

Write a program to calculate the distance how much Tiger jumps by using jumping(double distance) method which is extended from Animal and print the value by invoking that method from TestTiger class. Draw class diagrams for Animal, Tiger and TestTiger .

[SOLVED] Tape for a Turing Machine using Doubly-linked List in Java with full source code

By Anonymous -
Tape for a Turing Machine (Doubly-linked List) Short exercise in which you will code part of an existing project. In this case, you will be working with a doubly-linked list. To make this topic more interesting, the list that you work on will be part of a Turing Machine. A Turing Machine is a kind of very simple, abstract computing device that was introduced in the 1930's by Alan Turing as a way of studying computation and its limitations. The classes that you need for the lab are in a package named turing. You will define a new class named Tape in this package. You can find the Java source in the code directory. You should copy this directory into an Eclipse project. There will be errors, since the existing classes depend on the Tape class, which you have not yet written. Don't forget the Javadoc comments. A Class for Turing Machine Tapes A Turing machine works on a "tape" that is used for both input and output. The tape is made up of little squares called cell

[SOLVED] Branch Coverage, Statement Coverage and Path Coverage | Java Unit Testing

By Anonymous -
Create a directory called “TestClassValue” Hereafter, we call this directory <dir>. Create a Java class com.work.sample.FlawedClass in directory <dir>/src. (The actual path will obviously reflect the package structure.) 100% Branch Coverage & 100% Statement Coverage Add to the class a method called flawedMethodl that contains a division by zero fault such that it is possible to create a test suite that achieves 100% branch coverage and does not reveal the fault every test suite that achieves 100% statement coverage reveals the fault. Conversely, if you were able to create the method, then create two JUnit test classes com.work.sample.FlawedClassTestBCl and com.work.sample.FlawedClassTestSCl for class FlawedClass as follows: FlawedClassTestBCl should achieve 100% branch coverage of flawedMethodl and not reveal the fault therein. FlawedClassTestSCl should achieve 100% statement coverage of flawedMethodl and reveal the fault therein. Both classes should be

Report The Bug From The Following Source Code: import java.util.Arrays; /** * This class looks like it's meant to provide a few public static methods for * searching and sorting arrays. It also has a main method that tests the * searching and sorting methods. *  * TODO: The search and sort methods in this class contain bugs that can cause * incorrect output or infinite loops.
