Part 2 Design, implement, test, and debug a program that reads the file you created by the list in Part 1 and displays the records in a JFrame. You may either display all entries in the list at once or display them one at a time; the user interface is up to you. Protect against not being able to open the file. Flowchart
Then the shell displays another prompt and you can enter another command. When the background job finishes running, the shell displays a message giving both the job number and the command line used to run the command. To see the PID numbers type: ps 4. Assume that the following files are in the working directory: $ ls intro notesb ref2 section1 section3 section4b notesa ref1 ref3 section2 section4a sentrev Give commands for each of the following, using wildcards to express filenames with as few characters as possible. a.
Be able to use the debug step-into feature to step through the logic of the program and to see how the variables change values. D. Deliverables Section | Deliverable | Points | Lab 3 | Step 6: Program Listing and Output | 45 | E. Lab Steps Preparation: If you are using the Citrix remote lab, follow
Unit 4 Homework PT 1420 Brian Clear 6 April 2014 Unit 4 Assignment 1: Homework Short Answer 1. How do modules help you to reuse code in a program? Modules allow the programmer to write an operation once and then be executed any time it is needed. 2. Name and describe the two parts that a module definition has in most languages.
Then, download the attached Word file/Assignmen t. You may simply add your name to the header, insert your answers after the questions, and save the file under your own name. Please remember to answer in complete sentences/paragraphs and not in bullet points or phrases. Then, Click on “View/Complete Assignment” again. Scroll past the file you downloaded. Below the comments box, there is a Browse button.
Discuss briefly the type of database that is being used at your work and also the type of operating system used. 4.What is metadata and its importance? Using UMUC Library resources, research on metadata and provide some examples on the topic. Make sure to post links for your findings to assist and benefit class-members to better understand this important topic. 5.
Rename this document by clicking “Save As.” Change the file name so it reads Your Last Name Website Evaluation.docx. For example, if your last name is Smith, type “Smith Website Evaluation.docx”. 3. Save the document in a file format compatible with Microsoft Word 2010 or later. 4.
When a module is executing, what happens when the end of the module is reached? When a function is executing, it returns when the end of the block is reached, meaning the interpreter jumps back to the part of the program that called the function and the program resumes execution at that point. 4. What is a local variable? What statements are able to access a local variable?
The variable output is displayed with text as well as the result. The pseudo-code for a program provides the plain English description of the steps a program will execute. Pseudo-code is created before the coding begins and is used by the programmer in order to gain a greater understanding of the steps of the program. Below is the pseudo-code for as calorie counter and BMI program: * Program begins. * Create an array that will house five elements for the calorie intake amounts.
Check for potential problems and throw an exception. Check for potential problems, catch the mistake, and try to fix it. All of the above | 10. (TCO 2) Assume a class contains two non-static data members and one static data member. If two objects have been instantiated from the class, how many copies of the static data member exist?
