- Lab 02: Splitting a URL into pieces URLS are composed of five pieces: The scheme, also known as the protocol The authority (may further be divided into the user info, the host, and the port) The path The fragment identifier, also known as the section or ref The query string Read-only access to these parts of a URL is provided by nine public methods: getFile(), getHost(), getPort(), getProtocol(), getRef(), getQuery(), getPath(), getUserinfo(), and getAuthority(). Write a Java program which uses these methods to split URLS entered on the command line into their component parts.remove the value user inputted only not the key example Firstname [firstname]: John Middlename [middlename]: George Lastname [lastname]: Doe A for ADD D for DELETE Any key for END when enter 'D' lastname Firstname [firstname]: John Middlename [middlename]: George Lastname [lastname]: A for ADD D for DELETE Any key for END only the inputted will be remove not together the lastname names = {"firstname":"","middlename":"","lastname":""} choice = "A"while choice == "A" or choice == "D":print("\n\t A for ADD\n\t D for DELETE\n\t Any key for END")choice = input("\n\t Your choice: ")for k,v in names.items():print("\n\t "+k.capitalize()+" ["+k+"] : "+v)if choice == "A":key = input("\n\t Enter key: ")value = input("\n\t Enter value: ")names.update({key:value})for k,v in names.items():print("\n\t "+k.capitalize()+" ["+k+"] : "+v)elif choice == "D":delete_key = input("\n\t Enter key: ")names.pop(delete_key)for k,v in names.items():print("\n\t "+k.capitalize()+" ["+k+"] : "+v)else:print("\n\t…mysql> DESC bookauthor; mysql> DESC author; mysql> DESC book; | Field | Туре | Field | Туре | Field Тур | int(11 | varchai author_order | int(11 royaltyshare | decima: author_id isbn | author_id | int(1: | ssn lastname | firstname | varch: | phone | address | city | state | zip | varch: | varch: isbn var I name | type pub_id I price | advance I ytd_sales I pubdate var var | varch: | varch: | varch: | varch: | varch: | int dec | dec int mysql> DESC bookeditor; | dat | Field | Туре mysql> DESC editor; mysql> DESC publisher; editor_id | int(11) | varchar(1 | Field isbn | Field | Туре editor_id ssn pub_id | int(11) | varchar(40) varchar(40) varchar(20) varchar(2) lastname name firstname address | phone editor_position salary | city state

Tag: A user can type multiple tags (separated by a “;”). Save: When clicked, it saves the photo in a database along with the tags. Load: A user can specify one or more tags. Your app will find and show the first photo that had any of those tags. When there are multiple photos matching the criteria, the App should have an UI element to show them one by one, e.g., when the user slides a slider.Password Cracking Each student should be able to access* one PassXX.hash file. This file contains 4 unsalted md5 password hashes (md5 is commonly used for hashing passwords, though it is a bit weak for modern use. It is very important to salt passwords before hashing them, since leaving them unsalted makes them easier to crack. However, many sites fail to do this). Your assignment is to use Hashcat (or another password cracking or password "recovery" tool) to retrieve the original passwords from the hashes, and submit the password/hash pairs. Each set of hashes contains 1 very easy password and 3 slightly challenging passwords of differing format. Link to hashcat: https://hashcat.net/hashcat/ Note: You will also need one or more dictionaries to perform a dictionary attack. *access: Files are accessible based on your last name. You should see a large number of files that are not accessible due to your account having a wrong last name, and one file that is accessible that lacks…

- Using C# (Sharp) with Visual studio: Make a class of Book with 5 properties - ISBN, author, title, publisher, copyright date In the main method, create 5 instances of the Book class with different data for each Create a LIST and add each of the 5 objects to the LIST Use a foreach loop to display the ISBN, author, title, publisher, and copyright date in the LIST Create a DICTIONARY and add each of the 5 objects (key should be ISBN) Display author, title, publisher, copyright date for each book Create a SEARCH feature: ask the user to type in an ISBN. If the entry matches an item in your dictionary, display the author, title, publisher, and copyright date. If there are no matches, display "ISBN not found". Hint: use ContainsKey Create a REMOVE feature: ask the user to type in an ISBN to remove a book from the list. If the entry matches an item in your dictionary, remove the item and re-display your list. If there are no matches, display "ISBN not found".Bitcoin script: Alice is on a kayaking trip and is worried that her phone (which contains her private key) might fall overboard.
