Java: Please help with my Tester. I'm having a hard time figuring out my error. Thank you. What the tester requires: The AccountTester This class should consists of a main method that tests all the methods in each class, either directly by calling the method from the Tester or indirectly by having another method call a method. User and Bot information will be read from a file. A sample file is provided. Use this file format to aid in grading....
This project will use The Vigenere Cipher to encrypt passwords. Simple letter substitution ciphers are ones in which one letter is substituted for another. Although their output looks impossible to read, they are easy to break because the relative frequencies of English letters are known. The Vigenere cipher improves upon this. They require a key word and the plain text to be encrypted. Create a Java application that uses: decision constructs looping constructs basic operations on an ArrayList of objects...
[Continued] Your Course class should have: 1)a getter for the course 'code', so that it is read-only; 2)a getter and setter for the lecturer attribute, so that it is readable and writable; 3)a constructor that creates the associations shown in the UML diagram; 4)an enrolStudent method that adds a given Student object into the 'enrolled' set; 5)a withdrawStudent method that removes a given Student object from the 'enrolled' set and returns true if the student was successfully found and removed,...
Java Project Requirements: Account class Superclass Instance variables clearPassword String Must be at least 8 characters long encryptedPassword : String key int Must be between 1 and 10(inclusive) accountId - A unique integer that identifies each account nextIDNum – a static int that starts at 1000 and is used to generate the accountID no other instance variables needed. Default constructor – set all instance variables to a default value. Parameterized constructor Takes in clearPassword, key. Calls encrypt method to create...
Create a UML diagram to help design the class described in exercise 3 below. Do this exercise before you attempt to code the solution. Think about what instance variables will be required to describe a Baby class object; should they be private or public? Determine what class methods are required; should they be private or public? Write Java code for a Baby class. A Baby has a name of type String and an age of type integer. Supply two constructors:...
1. This project will extend Project 3 and move the encryption of a password to a user designed class. The program will contain two files one called Encryption.java and the second called EncrytionTester.java. 2. Generally for security reasons only the encrypted password is stored. This program will mimic that behavior as the clear text password will never be stored only the encrypted password. 3. The Encryption class: (Additionally See UML Class Diagram) a. Instance Variables i. Key – Integer...
Draw the UML DIAGRAM ALSO PLEASE DRAW THE UML DIAGRAM.ALSO in java should use the program in java For this task you will create a Point3D class to represent a point that has coordinates in three dimensions labeled x, y and z. You will then use the class to perform some calculations on an array of these points. You need to draw a UML diagram for the class (Point3D) and then implement the class The Point3D class will have the...
Assignment Requirements I have also attached a Class Diagram that describes the hierarchy of the inheritance and interface behaviors . The link to the PDF of the diagram is below MotorVehical.pdf Minimize File Preview User Define Object Assignment: Create a Intellij Project. The Intellij project will contain three user defined classes. The project will test two of the User Define Classes by using the invoking each of their methods and printing the results. You are required to create three UML...

This is the question about object-oriend programming(java) please show the detail comment and prefect code of each class, Thank you! This question contain 7 parts(questions) Question 1 Create a class a class Cat with the following UML diagram: (the "-" means private , "+" means public) +-----------------------------------+ | Cat | +-----------------------------------+ | - name: String | | - weight: double | +-----------------------------------+ | + Cat(String name, double weight) | | + getName(): String | | + getWeight(): double | |...
