Description

Write a menu driven program that either accepts words and their meanings, or displays the list of words in lexicographical order (i.e. as in a dictionary). When an entry is to be added to the dictionary you must first enter the word as one string, and then enter the meaning as separate string. A word may have more than one meaning, and may be entered at separate times. When this occurs, place each successive meaning on a separate line. This new meaning must be preceded by a dash. For example, if you enter the following words and with their meanings in the following order: Library, School, Cup, and School, then your output should be a display as shown in the Figure 1. Figure 1.

Write a menu driven program that either accepts words and their meanings, or displays the list of words in lexicographical order (i.e. as in a dictionary). When an entry is to be added to the dictionary you must first enter the word as one string, and then enter the meaning as separate string. A word may have more than one meaning, and may be entered at separate times. When this occurs, place each successive meaning on a separate line. This new meaning must be preceded by a dash. For example, if you enter the following words and with their meanings in the following order: Library, School, Cup, and School, then your output should be a display as shown in the Figure 1. Cup – a container from which we drink. Library – a collection of books School – a place of learning - any group of fish Figure 1. Another requirement - from time to time words become obsolete. When this happens, such word must be removed from the dictionary. Use the JOptionPane class to enter the information. Use the concept of linked list to carryout this exercise. You will need at minimum the following classes: • A WordMeaning class that hold the name of a word and its meaning. • A WordMeaningNode class that creates the node of information and its link field. • A WordList class that creates and maintain a linked list of words and their meanings. • A Dictionary class that test your classes. For the output, the program should produce two scrollable lists: • The current list of words and their meanings, and • The list of the deleted words. You need not list the meanings, just the words. NB. The linked list must be designed from first principle. Do not use the pre-defined class LinkedList found in java.util; nor array; nor ArrayList class.

University of Phoenix 3 Dimensions of Risk Management Discussion & PPT

Choose an organization from the education, financial, or healthcare sector to study throughout this course. Each week you explore different aspects within the IT division of the organization including: 3 dimensions of risk management Potential risks during a server database migration Risk assessment and continuity plan Request for proposal for new web servers Monte Carlo method You have been asked by the CIO of the organization you chose to create Microsoft®PowerPoint® presentation, along with an accompanying summary guide handout, for the managers of the IT, Accounting/Finance, and Engineering departments to inform them of the three dimensions of risk management.The three dimensions of risk management shape the organizational framework of project risk management and determine the degree of freedom used to classify various realizations of uncertainties, resulting in a formalized systematic analysis of physical systems.Research information about the organization you chose to complete this week's assignment.Part A:Create?a 4- to 6-slide, media-rich Microsoft® PowerPoint® presentation which describes each of the three dimensions, its definition, values, and importance to your company. Identify the potential security risks to an organization in each of the following outsourcing situations: The implementation of an external service provider for data/security protection The use of contractual service providers for processing information systems applications such as a payroll, human resources, or sales order taking The use of an offshore company to support your desktop computers The use of an third-party governance to provide network support Note: Media-rich presentations should include multimedia such as graphics, pictures, video clips, or audio.Part B:Create a 1-page Microsoft® Word Summary Guide on this presentation. Include the following: Risk considerations during the development and implementation of information systems The importance of Information systems risk management A summary of the organizational risk management framework The risk register of the highest risk of information security to the organization

XML TaggingThe final step to completing our shop website is, to store the user's purchases in a file. Now that you have a Shopping Cart page that stores the items in cookies and displays them to the user, modify the Shopping Cart page to include a submit button.Once the submit button is clicked, the user is directed to a page with a Thank You message, you can call it confirmationpage.php. The page needs to store the items the user purchased into an XML file by either parsing the contents of the cookies created in the Shopping Cart page, or parsing the contents of the array stored in the cookie (depending on which strategy you chose to solve last week's assignment. The XML file, named purchases.xml needs to include the following items:Item nameItem priceIt is up to you to determine the format of the XML file, you are welcome to follow the below suggested format if you want:<purchasedItems><Item><ItemName></ItemName><ItemPrice></ItemPrice></Item></purchasedItems>Submit your code as well as a test plan in a 4- to 5-page Microsoft Word document consisting of:Screenshots of your project (showing design, data entered, and displayed)A paragraph explaining how you tested your projectAll HTML or PHP script zipped under one fileSubmission DetailsName your document SU_ITS4112_W4_Project_LastName_FirstInitial.zip.Support your responses with examples.Cite any sources in APA format.

Southern New Hampshire University Validating User Input and Debugging Program

OverviewMany Java programs that you create will receive and process user input. In order to ensure that user input is accurate, you will need to use input validation and exception handling. For example, if you ask for a zip code, you want to ensure the user inputs a five-digit number. In this activity, you are given “buggy” code for a paint program that calculates the number of cans of paint required to paint a wall, given the wall’s height and width. You will need to debug the code and improve it by adding code to validate user input and handle exceptions.PromptFor this assignment, you will complete the paint program by debugging the original code and adding code that validates user input and handles exceptions. Use the Uploading Files to Eclipse and the Downloading Files from Eclipse Tutorial tutorials to help you with this project.DebuggingOpen the Virtual Lab by clicking on the link in the Virtual Lab Access module. Then open your IDE. Upload the Paint1.zip folder and review the code for the Paint1.java file.Find and fix the three errors in the given code.Use the input values below to test your program. If you found and fixed all errors, your output should exactly match what is below.TIP: When you run your program in Eclipse, it will prompt you to enter input in the Console window. If you cannot find this window, go to Window, then Show View, then Console.Input Validation and Exception HandlingReview the code, looking for the two code blocks where user input is required.Implement a do-while loop in both blocks of code to ensure that input is valid and any exceptions are handled.TIP: Consider using a try-catch block for exception handling, but it is not required.Use the two sample invalid inputs below to test your program. Your program should respond to each by prompting the user to enter valid input. This should continue to loop until valid input is received.THINK: Why is 0 invalid input for this problem? What is the user being asked to input?Guidelines for SubmissionAttach your completed Paint1.java file to the assignment submission page.Module Six Assignment RubricCriteriaProficient (100%)Needs Improvement (75%)Not Evident (0%)ValueDebuggingDebugs a class so that no errors remain and calculations work correctlyMeets some “Proficient” criteria, but with errors or exclusions such as one or two remaining bugsDoes not attempt criterion30Input Validation and Exception HandlingAdds loops to validate all user input and handle exceptions so that code passes all test casesMeets most “Proficient” criteria, but with errors; areas for improvement may include ability to handle all test casesDoes not attempt criterion70Total: 100%
