In Java please help with the following: Define a class Registration to implement course registration/withdrawal of students. The program should place the code into a try-catch block with multiple catches to check for the validity of various attributes based on the following criteria. a. Student ID must start with a letter and should be followed by four digits. b. The default number of courses must be at least 3. -Print suitable error matches within the catch block. If any of the criteria mentioned above is not fulfilled, the program should loop back and let the user enter new data. -Add methods for the number of courses registered and withdrawn. Create your own exception class which will check inside the method for the courses registered so that after the registration, the maximum number of registered courses should not be more than 6. Also, check inside the method for course withdrawal so that the number of courses after the withdrawal does not go less than 2. -Invoke the…
A binary operator is an operation that is performed on two operands. For example, addition is a binary operator that adds two operands (e.g., 2 + 4). In the provided UML diagram, all binary operators have two operands and an execute method that performs the appropriate operation on the operands. The AddOperation class should add the two operands. The SubtractOperation class should subtract the two operands. Here is an example of how a binary operator could be used: IBinaryOperator operator = new AddOperator(8, 12);System.out.println(operator.execute()); // should print 20operator.setLeftOperand(18);System.out.println(operation.execute()); // should print 30 crate a Main.java to test your code

6. Design a Java class with a main method that does the following. You must include a meaningful comment for main and each method a. Main invokes a method readScores to read input from a file (name of your choice) that contains the name of the bowlers (no more than 25) and their bowling scores (two scores per bowler). The program stops reading values when it has reached the end of the file. For example, the file might contain: Bob 203 176 Jane 210 253 Jack 300 189 Eileen 220 298 • As the method reads the data, it stores the name into a String array and the average of the two bowling scores into an array of double. • The method returns the actual number of bowlers read in b. Main then invokes a method computeOverallAvg to: compute (a) the overall average score of all the bowlers combined, (b) the average score and name of the bowler with the highest average score and (c) the average score and name of the bowler with the lowest average scores. print to the console (a) the overall average…
Using python: (see attached- I need help with part Q2) Add a method to the person class name it (username) that takes the email and take off all the part from @ and after, and assigns the string before the @ sign to a variable username. For example: malabdullah@UT.edu, the method will assign 'malabdullah' as the username.
Please answer in python Write a method called add_racer which takes in a Boat object and adds it to the end of the racers list. The function does not return anything. Write a method called print_racers which loops through racers and prints the Boat objects. This function takes in no parameters (other than self) and returns nothing. Write a method called count that returns the number of racers. Write a method called race. The race function calls the move function for all of the racers in the BoatRace. Once all the racers have moved, call the print_racers method to display information about the progress of each boat. Then, check if any of the racer’s current_progress is greater than or equal to the race’s distance. If so, then return a list of all of the racers whose current_progress is greater than or equal to distance. If no racer has finished the race then repeat the calls to move and check until at least one racer has finished the race. Examples: Copy the following if…
PLEASE ANSWER IN C++ Begin by writing a Student class. The public section has the following methods:Student::Student()Constructor. Initializes all data elements: name to empty string(s), numeric variables to 0.bool Student::ReadData(istream& in)Data input. The istream should already be open. Reads the following data, in this order:• First name (a string, 1 word)• Last name (also a string, also 1 word)• 5 quiz scores (integers, range 0-20)• 3 exam scores (integers, range 0-100)Assumes that all data is separated by whitespace. The method returns true if reading all data wassuccessful, otherwise returns false. Does not need to validate or range-check data; if one of the quiz orexam scores is out of range, just keep going.bool Student::WriteData(ostream& out) constOutput function. Writes data in the following format. Each student’s data is on one line.• First name (left justified, 20 characters)• Last name (left justified, 20 characters)• 5 quiz scores (each right justified in a…
This lab must be done in C++ Assignment: In cryptography, encryption is the process of encoding a message or information in such a way that only authorized parties can access it. In this lab you will write a program to decode a message that has been encrypted. Detailed specifications: Define three classes. Each one should be in a separate file. You can choose to define the class and its functions inline, all in a header file, or have a .h and .cpp file for each class. Abstract base class with the following: A variable to hold an encrypted message. This variable should be a string which is initialized in the constructor. A status variable that will tell whether the message was loaded successfully. A constructor that receives one parameter: a string variable with a file name and uploads its content to the string variable that is supposed to store it. A pure virtual function called decode. This function will be defined in derived classes. A function that prints the message on the…

Please do in Java In many computer systems and networks,different users are granted different levels of access to different resources. In this case, you are given a int[] rights, indicating the privilege level of each user to use some system resource. You are also given a int minPermission, which is the minimum permission a user must have to use this resource. You are to return a String indicating which users can and cannot access this resource. Each character in the return value corresponds to the element of users with the same index. 'A' indicates the user is allowed access, while 'D' indicates the user is denied access. Constraints users will contain between 0 and 50 elements, inclusive. Each element of users will be between 0 and 100, inclusive. minPermission will be between 0 and 100, inclusive. Examples a) {0,1,2,3,4,5} 2 Returns: "DDAAAA" Here, the first two users don't have sufficient privileges, but the remainder do. b) {5,3,2,10,0} 20 Returns: "DDDDD"…
(2) True or False: Sometimes there are two or more possible matches for an invocation of a method, but the compiler cannot determine the most specific match. Ambiguous invocation causes a compilation error. True False Give an explanation for the answer. Thank you
