In Java, every source file must have the same name as the class declared in the file.

python class Student:def __init__(self, first, last, gpa):self.first = first # first nameself.last = last # last nameself.gpa = gpa # grade point average def get_gpa(self):return self.gpa def get_last(self):return self.last def to_string(self):return self.first + ' ' + self.last + ' (GPA: ' + str(self.gpa) + ')' class Course:def __init__(self):self.roster = [] # list of Student objects def drop_student(self, student):# Type your code here def add_student(self, student):self.roster.append(student) def count_students(self):return len(self.roster) if __name__ == "__main__":course = Course() course.add_student(Student('Henry', 'Nguyen', 3.5))course.add_student(Student('Brenda', 'Stern', 2.0))course.add_student(Student('Lynda', 'Robinson', 3.2))course.add_student(Student('Sonya', 'King', 3.9)) print('Course size:', course.count_students(),'students')course.drop_student('Stern')print('Course size after drop:', course.count_students(),'students')

There is no limit to the number of arguments that may be put into a catch block.

In a catch block, there is no limit to the amount of arguments that may be used.

Integer userValue is read from input. Assume userValue is greater than 1000 and less than 99999. Assign tensDigit with userValue's tens place value. Ex: If the input is 15876, then the output is: The value in the tens place is: 7 2 3 public class ValueFinder { 4 5 6 7 8 9 10 11 12 13 GHE 14 15 16} public static void main(String[] args) { new Scanner(System.in); } Scanner scnr int userValue; int tensDigit; int tempVal; userValue = scnr.nextInt(); Your code goes here */ 11 System.out.println("The value in the tens place is: + tensDigit);

Python3 code: Create a simple text file called mycandy   The first line of the file will be   Candy Name, Candy Calories, Total Fat Grams   Next, add five lines to the file by hand using your favorite five candy bars information. Each line's data will be separated by commas.   Create a class called Candy which keeps track of the three pieces of information   Read in the file line by line and create a Candy class instance for each candy bar you have, and add that new instance to a list.   Once you have the list created, loop through the list and print the candy bar info out to the console   Add a line of code to append one more candy bar’s information to your mycandy file.  Show what your new text file looks like after the append
