- 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.Look at the header of the method below, and then implement a sample call to it in your code.private static void ShowValue ()You are responsible for adding the appropriate testing code to your main. a. The getValedictorian method returns the valedictorian of the class, that is the student with the highest grade point average. Implement this new method. b. The getHonorsPercent method returns the percentage of students in the class who are in the honors program. Use 3.75 as the cutoff GPA. Implement this method. Also print the list of students, by using the isHonor method, in the Honors program. c. An alternate implementation for the School class is being considered, in which the students are stored in an ArrayList instead of an array. Show how the declaration of the data field students would look in this alternate design.

- A method is implemented to compute a formula that involves dividing a quantity by a variable y. If y is 0, then an ArithmeticException will be thrown. How should you handle this situation? Here are some alternatives: 1. Ignore the problem and let your method throw an ArithmeticException. 2.Test for y==0 before doing the computation and, if found, print an error message and return 0. 3.Surround the computation with a try/catch block and print an error message in the catch block before returning 0. a. Compare these three alternatives. That means talk about how each is the same as or different than the other two. b. Is there a fourth alternative that is better than these three? If there is, give it along with a justification. If there is not, explain why not.What type of information does the following method return? public static void methodRankPoints(double points) int double nothing object Which statement is correct? The while loop repeats a set of code while a condition is not met. The number of iterations required of a while loop is always known before the while loop begins. The while loop repeats a set of code while a condition is met. The while loop does not require code to be added to manage iteration during each loop. Which of the following statements is true with regard to java exceptions? A try block can be followed by multiple catch blocks. A program automatically terminates immediately after a catch block is executed. Only one try/catch block is allowed in a single method. A try-catch is required in all methods.Problem: To write the JUnit test cases for our methods, you need to create two test methods: testLeapYear: This method should test if the isLeapYear method returns true for a given leap year. For example, you can choose the year 2020 and verify if the method returns true for it. If it does, the test will pass. If it doesn't, the test will fail. testNotLeapYear: This method should test if the isLeapYear method returns false for a given non-leap year. For example, you can choose the year 1900 and verify if the method returns false for it. If it does, the test will pass. If it doesn't, the test will fail. --------------------------------------------------------------------------------------------------------------------------------------------------------- import static org.junit.jupiter.api.Assertions.assertTrue; import org.junit.jupiter.api.Test; public class LeapYearTest { // Test case to check if a year is a leap year @Test public void testLeapYear() { //create…
