- Using explicit constructor can avoid type conversions. Group of answer choices True Falsejava code quation using ExceptionProgramme Leader of ITMB wants to check whether the student number and GSM numberentered by the student for the programming contest is valid or not.Write a Java program to read the Student ID and GSM Number of a student. Use a methodcalled ValidityDetails () for checking the validity of details entered.If the Student ID ends with the characters ST and contains more than 6 letters or if the MobileNumber does not contain exactly 8 digits, throw a user defined exceptionInvalidDetailsException.If the details entered are valid, display the message ‘”correct details are entered!!!” otherwisedisplay “Entered invalid details!!!!”Q4: You are a teacher. You would like your students to use a software package, but the school's budget does not include enough money to buy copies for all the students. Your school is in a poor neighborhood, and you know most of the parents cannot afford to buy the software for their children. b) Suppose the methods you try do not work. Will you copy the software or decide not to use it? Give some arguments for and against your position. Explain why you think the arguments on your side are stronger
- . Show the example to override the methodComplete method __init__ in the following class. (It's only missing an assignment to a radius instance variable.)- a computer store management application with different jframes for customers and orders etc., using Swing library of Java programming language. Choose one of the applications above. Project logic is completely up to you. However, your application is supposed to include at least 3 different windows, in other words, 3 JFrames and you should create connections between those frames according to the logic of your application. Those JFrames can be accompanied by normal (model) java classes as well. In your application, file writing and file reading methods should be utilized. When submitting your project, you are required to have following parts in your paper; • A general description of the application. • Brief explanation of the logic of using different components in the application. • Screenshots of all possible windows. • Source codes (Showing each class separately).
- 8. What is the difference between equals() and method and == operator?.True or False: If methodA() has an equals() method that overrides the one in the Object class, then in our JUnit test for methodA(), assertEquals() will use the version of equals() in methodA().Must be written in Python. Please include docstring and show how output should look like. Remember that all data members should be private. An object can access it's own private data members directly. It can also access the private data members of other objects of the same class directly. But when accessing a private data member of an object of another class, it needs to call the appropriate get method. If that sounds complicated, just remember this: if a method is in the same class as a private data member, then it can access that data member directly, otherwise, it needs to use a get method. Write a class named Point that has two data members, x_coord and y_coord, representing the two coordinates of the point. It should have: an init method that takes two arguments, an x-coordinate and y-coordinate (in that order), and uses them to initialize the two data members. get methods for the two data members: get_x_coord and get_y_coord. a method named distance_to that takes a Point object…
- 4.interfacegiven below. In the main method also include a simple usage example.Here are the rules of N x N Tic-Tac-Toe game:• Players take turns placing characters into empty squares (" ").• The first player A always places "X" characters, while the second player B always places "O" characters.• "X" and "O" characters are always placed into empty squares, never on filled ones.• The game ends when there are N of the same (non-empty) character filling any row, column, or diagonal.• The game also ends if all squares are non-empty.• No more moves can be played if the game is over Must be outputted in the console not with gui.Rules: Corner cases. By convention, the row and column indices are integers between 0 and n − 1, where (0, 0) is the upper-left site. Throw an IllegalArgumentException if any argument to open(), isOpen(), or isFull() is outside its prescribed range. Throw an IllegalArgumentException in the constructor if n ≤ 0. Unit testing. Your main() method must call each public constructor and method directly and help verify that they work as prescribed (e.g., by printing results to standard output). Performance requirements. The constructor must take Θ(n^2) time; all instance methods must take Θ(1)Θ(1) time plus Θ(1)Θ(1) calls to union() and find().In this activity, you will modify a method (function) to simulate a financial transaction check. Just like when you use your debit card at an ATM. The requested transaction either gets accepted or declined by the bank. By modifying an if-else statement you will be able to perform this check. If the transaction requested cannot be processed due to insufficient funds, tell the user. If the transaction can succeed, then tell the user that that is the case. Your task: Add to the MathMachine.java file so that it has a complete codelblock called the transactionRequest() method. Fill in the Boolean logic in the if statement so that the correct message is sent to the user. Notice the use of this.cardBalance inside the MathMachine class. See how it is private to the MathMachine class? Consider how it might be used in your transactionRequest() method to solve the boolean logic issue. The keyword "this" means "this class". In our example, it means that we're dealing with the MathMachine class.…
