Section 19.4 talks about how to change the recovery algorithm to make savepoints and to roll back to a savepoint. Section 19.9.3 talks about save points.

You will implement some methods in the UndirectedGraph class. The UndirectedGraph class contains two nested classes, Vertex and Node, you should NOT change these classes. The graph will store a list of all the vertices in the graph. Each vertex has a pointer to its adjacent vertices. To get started, import the starter file, Undirected.java into the graphs package you create in a new Java Project. Please do not change any of the method signatures in the class, but you can add any helper methods you deem necessary. Implement the methods described below. You are free to test your code however you prefer. Vertex Class (DO NOT EDIT)The vertex class holds information about the vertices in the graph. It has an int val, a Vertex next that refers to the next vertex in the list of vertices (not necessarily an adjacent vertex), and a Node edge that starts the list of adjacent vertices. Node Class (DO NOT EDIT)This is a simple class to represent an adjacency list of a vertex in the graph.…

Please Code in JAVA. Type the code out neatly. Add comments . (No need for long comments). Dont add any unnecesary code or comments. Do what the attached file says. And call it a day. Thanks !

In python:  The program should ask users for their email address and password for connecting to the mail server. You can create a new gmail account and use it for this assignment. Once the connection is complete, the program should ask for the receiver''s email address, and lastly send the email. Write "Hello" for the subject and "Email from Python" as body. Use the getpass library to hide password from shell. Instantiate an object and call it. Submit the .py file as well as screenshots showing the code runs and email received.

How do I change numCastMembers retrieved to 1 to numCastMembers retrieved to 0? Test: OK --- method getNumMinutes exists OK --- method getNumCastMembers exists OK --- method getMovieName exists OK --- method isKidFriendly exists OK --- method getCastMembers exists OK --- movieName retrieved Flick OK --- numMinutes retrieved to 0 OK --- isKidFriendly retrieved to false OK --- numCastMembers retrieved to 1 OK --- getCastMembers returns copy of the original array with the same content OK --- movieName retrieved Tape OK --- numMinutes retrieved to 10 OK --- isKidFriendly retrieved to true OK --- numCastMembers retrieved to 3 OK --- getCastMembers returns copy of the original array with the same content OK --- movieName retrieved Screening OK --- numMinutes retrieved to 120 OK --- isKidFriendly retrieved to false OK --- numCastMembers retrieved to 5 OK --- getCastMembers returns copy of the original array with the same content OK --- movieName retrieved Film OK --- numMinutes retrieved to…

CHALLENGE ACTIVITY 487180.3542414.qx3zqy7 Jump to level 1 1.3.6: Output basics. For activities with output like below, your output's whitespace (newlines or spaces) must match exactly. See this note. Write code that outputs variable num_pants as follows. End with a newline. Ex: If the input is 4, then the output is: Will there be 4 pants? 1 ""Our tests will run your program with input 4, then run again with input 7. 2 Your program should work for any input, though. 455W NI 3_num_pants = input() 4 print("Will there be", numPants, "pants?") www Your code goes here 5 6 www 1 2 3 4 5 6

It will use a class called NameHelper (which you will write).  This class will provide methods to load the data files and to fetch name rankings by year.  The JavaFX class will be using NameHelper according to the following UML, so make sure your data helper has the methods defined below:   What does the (~) mean in the attached diagram.
