In this laboratory work, you are expected to write a c# console application to make some operations about the customers. Operations and required featurest that you need to cover in your program are following: • Add: This function adds a new person to json file. You need to get inputs from user and adds the new one into json file. • Display: This function displays all people in your json file. • Search: This function let you search with the user id. • Create Password: This function will create a random password for the user and user may choose the length of the password. Password may include numbers and characters. • Exceptions: You need to handle exceptions as well. You should at least handle 3 of exceptional cases. For the case that file can not be found, It is mandatory to catch the exception. Sample json string: "FirstName": "Kaan", "LastName": "OZAYDIN", "EmployeeId": 101, "Email": "", "Password": "Address": ( "ZipCode": "06460", "State": "Ankara", "Country": "Turkey" "FirstName":…

One common use of a hash table is to build a glossary, or dictionary, of terms.In this section, we demonstrate one way to use a hash table for just such ause—a computer terms glossary.The program works by first reading in a set of terms and definitions from atext file. This process is coded in the BuildGlossary subroutine. The structureof the text file is: word,definition, with the comma being the delimiter betweena word and the definition. Each word in this glossary is a single word, but theglossary could easily work with phrases instead. That’s why a comma is usedas the delimiter, rather than a space. Also, this structure allows us to use theword as the key, which is the proper way to build this hash table.Another subroutine, DisplayWords, displays the words in a list box so theuser can pick one to get a definition. Since the words are the keys, we can usethe Keys method to return just the words from the hash table. The user canthen see which words have definitions.To retrieve a…
Assume you have a folders of (images and videos) in your computer which contain some random mix numerical values. Your task is to separate images (e.g odd values) and videos (e.g Even values). So that all the images and videos are stored in separate folders (lists). While separating make sure that any of the folder (lists) should not contain any duplicate file or duplicate value. In this task images and videos odd & even numbers and folder means a single list of mix value. e.g: linkedlists (odd, even). Design a method for above task which will create two separate linked lists and write main method to test your program. FOLDER (VIDEO AND IMAGES:ODD AND EVEN VALUES) LIST 0: [2, 44 , 24 , 82 , 33 , 44 , 55 , 11 , 2 , 44 , 55]: EVEN VALUES_LIST 1: [2, 44 , 24 , 82]: A=2, B=44, C=24, D=82 ODD VALUES:_LIST 2: [33 , 44 , 55 , 11]: A=33, B=45, C=55, D=11
The goal for Lab06b is to use the provided Student class (ATTACHED IN IMAGE) and create an array of Student objects that are stored in a School object. This program uses a Student class that is provided and shown below. The class is placed in its own separate file and should not be altered. This program sequence started with Lab06a. It is a reminder that it is the same Student file used by Lab06a. This lab will add data processing to the earlier Lab06a. This program will continue with the Lab06b program that performs some data processing on the Student records. For this lab 10 Student objects need to be constructed and placed in a students array, which is stored in a School object. You actually did this already for Lab06a. You also need to complete the School constructor, addData method and toString Method, which were in Lab06a. Feel free to just copy them over. You need to complete three bubbleSort methods; one that sorts according to the student gpa., one for age and one for name.…

/*TASK 5. Implement part 1 of the report. You need to read data from input.txt file, store it into array of items (called items) and write it in a formatted form to the output file. Code, debug and present it in the best possible format. Hint: It might be helpful to format the String coming from toString( ) method using String.format( ) method, which works similar to System.out.prinf. Hint2: You might have to close and delete existing output .doc or .txt file from its folder * public class YourUserName_hw7 { static Item [ ] items = new Item [200];//an array of Items static EdibleItem [ ] edibleItems;//an array of Edible Items static int countEdibleitems = 0;//count edible items static String pageHeader; //save the header //main( ) method runs the program public static void main(String[ ] args) throws FileNotFoundException { double sum = 0, average = 0; //Optional - create a new input file //CreateInput.createInputFile( );…

ABC airport has a list of travelers kept in a file (see below) and has asked you to write a complete Q7 program that reads from the user a filename and a destination and prints all the travelers (Format: --Last name, First name) that travelled to that destination. O points if you code everything in main. You should have at least 2 methods: main and one other method (excluding the readFile method). You can assume that the method: public static String (] [] readFile (String filename) is available (in the same program). That is, you can just use it to read from the file. It returns a String[][] with as many rows as lines in the file, and each row will have as many Strings as comma-separated items on that line in the file. For the sample file below, the String[]] will look like this: [ ["Alex Aiono","Johanesburg", "8-6-2017"], ["Marcus Schultz","Marrakech","1-24-2017"], ..] Sample file (travelers.txt) DO NOT HARDCODE THE FILE NAME.
