Java Programming Basic Tasks LoopsComputer, Input Analyzer and StringMainpulator

By Hassnain Jamil -

Task01: Problem E6.1 a,b,c,d from the Book (not e).  Create a class called LoopsComputer.  Use the following method names for each part.  A) computeEvenSum(), B) computeSquareSum(), C) printPowers(), D) oddSum().   For part d, you will use two input parameters “a” and “b” as ints.  Each method should print your answer.  (All these methods should have a return type of void).

Task02: Problem E6.2 a,b,c,d from the Book.  Create a class called InputAnalyzer.  Use the following method names for each part of the problem.  A)  findSmallLarge(), B) countEvenOdd(), C) cumulativeTotal(), D) findAdjDuplicates().  Each method should create a scanner and ask the user for input.  You should continue to read input while the user enters integers.  (i.e. if the user enters “Q”, then you should exit your loop.  The hasNextInt()method from the Scanner class returns true if the user enters an int, and false otherwise.  You can use the return value from this method as your loop condition).  A single prompt will work in this case as well.  Ask the user for a list of numbers, and then process them accordingly in each loop.

Task03: Problem E6.3 a,b,c,d,e from the Book.  Create a class called StringManipulator.  Create a single instance variable of type String for this class called  line.  (Because it will store a line of text).  Create a constructor for this class that accepts a single parameter as a String, and initializes the instance variable line to this parameter.  In your main method of your tester class you will prompt the user for a line of text  as a String (you can use the nextLine() method from the Scanner class), and use this String to construct a new StringManipulator object.  Then you will call your methods.  Use the following method names for each part of the problem.  A) printUpper(), B) printEveryOther(), C) vowelsToUnderscore(), D) printVowelCount(), E) printVowelPositions().  These methods should each print the solution to each part of the problem, using the instance variable line for the calculations.

Task04: Take a screen-shot(s) of your final output, which should show output for Task01, Task02, and Task03.

[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
