- I may need help with this project: A combined cycle gas turbine power station requires a webbased system to manage the storage and installation of spare parts and the acquisition of new parts from the Central Storage Warehouse (the CSW). The powerstation maintains an inventory of all the parts it owns comprising: part name, description and specification. There are many copies of some parts – each part has a unique ID, known as an asset tag number. The asset tag number is used when there is damage to particular parts. The power station also keeps a catalogue of all the possible spare parts types used.Only registered maintenance engineers and team leaders are allowed to install and repair parts on the plant. Maintenance engineers and team leaders can use the parts catalogue tosearch for part types and can also search the parts inventory. Maintenance engineers work in teams, currently: electrical, mechanical and environmental. Each team has its own team lead. However, the system needs to…You will develop a client side and a Servlet program that will work with a database. 1. The client (front end) should have a title “NJIT Credit Union”, centered. 2. The client should have a background color. 3. The client should have a text field with label ‘UserID' where user will enter userID (integer) and a Submit button with text "Submit". 4. An unsuccessful authentication should have a message printed on the screen, in red, stating that "Your authentication has failed, please try again." (no pop up message). At this point the text field should get cleared and ready to accept a new input. Your program should not exit. 5. A successful authentication should be followed by a message on the screen, in green, stating that "Your authentication is successful" (no pop up message). 6. There should be two other text boxes with label "Deposit" and "Withdraw" where user will enter an amount (you should accommodate for decimals). These two text boxes should only be enabled after successful…This is the question I am stuck on - A personal phone directory contains room for first names and phone numbers for 30 people. Assign names and phone numbers for the first 10 people. Prompt the user for a name, and if the name is found in the list, display the corresponding phone number. If the name is not found in the list, prompt the user for a phone number, and add the new name and phone number to the list. Continue to prompt the user for names until the user enters quit. After the arrays are full (containing 30 names), do not allow the user to add new entries. Use the following names and phone numbers: Name Phone # Gina (847) 341-0912 Marcia (847) 341-2392 Rita (847) 354-0654 Jennifer (414) 234-0912 Fred (414) 435-6567 Neil (608) 123-0904 Judy (608) 435-0434 Arlene (608) 123-0312 LaWanda (920) 787-9813 Deepak (930) 412-0991 This is the code I have.

- I need help with this one please, already tried but still getting a wrong answer Scenario You have been tasked with building a URL file validator for a web crawler. A web crawler is an application that fetches a web page, extracts the URLs present in that page, and then recursively fetches new pages using the extracted URLs. The end goal of a web crawler is to collect text data, images, or other resources present in order to validate resource URLs or hyperlinks on a page. URL validators can be useful to validate if the extracted URL is a valid resource to fetch. In this scenario, you will build a URL validator that checks for supported protocols and file types. Task Create two lists of strings – one list for Protocol called valid_protocols, and one list for storing File extension called valid_fileinfo. For this take the protocol list should be restricted to http, https and ftp. The file extension list should be .html, .csv and .docx. Split an input named url, and then use the first…For this assignment, you are to use the started code provided with QUEUE Container Adapter methods and provide the implementation of a requested functionality outlined below.

You have to keep the records of customers and cars. Now the shop has multiple cars and customers. The customers have two types one is member and the other is new customer. The customers have some operations as add customer which add the details of the customer in the system, view customer which prints the details of the customer and is valid which checks whether the NIC is given or not. The internal details of is valid operation only is kept hidden with the help of abstraction. The details of customers are name, contact, NIC, address and balance. The car has four types Honda, Toyota, Suzuki and Daihatsu. The common operations of car are add car which add the details of car in the system, view car which prints the details of the car, issue car which updates the car detail (available = false) that car is given on rent and is…
- When an author produces an index for his or her book, the first step in this process is to decide which words should go into the index; the second is to produce a list of the pages where each word occurs. Instead of trying to choose words out of our heads, we decided to let the computer produce a list of all the unique words used in the manuscript and their frequency of occurrence. We could then go over the list and choose which words to put into the index. The main object in this problem is a "word" with associated frequency. The tentative definition of "word" here is a string of alphanumeric characters between markers where markers are white space and all punctuation marks; anything non-alphanumeric stops the reading. If we skip all un-allowed characters before getting the string, we should have exactly what we want. Ignoring words of fewer than three letters will remove from consideration such as "a", "is", "to", "do", and "by" that do not belong in an index. In this project, you…ScenarioI want to create an INDEXCEPTION value of the unique vowels and unique consonants that the name that was given to you can create.InputA string of the name that was GIVEN TO YOU. CASE SENSITIVE.ProcessStep 1: For every unique vowel of a name, you need to get the first index of that vowel from the original string.Step 2: For each vowel index you get from step 1, you will get the unique consonant from that position. if the index is out of scope of the consonant array, ignore that vowel index.Step 3: For each unique consonant that you get from step 2, you need to get the first index of that consonant from the original string.Step 4: Get the value of indexception by adding all index you get from step 3.OutputTO BE DISPLAYED- 2 lists that consists of unique vowels and unique consonants- The vowel, the vowel index, the consonant, the consonant indexFINAL OUTPUT- The total indexception value of the name that was given to you.IN JAVA Script - There is one operator in JavaScript, which is able to provide the rest of the partition function.
