- How many parameters does a catch block have the capacity to handle?What is the value of the expression max().) O None It raises a ValueError exception. O It raises an IndexError exception.First, create the custom exception class called OutOfStockException by creating a new class that extends the Exception class The class has a single constructor that takes a single argument, a string called message. The message argument is passed to the parent class (Exception) via the super keyword. Create the Store class and import the java.util.HashMap and java.util.Map classes The Store class is defined with a private Map called products, which is used to store the product names and their corresponding quantities. Create a default constructor that initializes the products map with three items: "apple", "banana", and "orange", with respective quantities of 10, 5, and 0. Define thepurchase method , which takes two arguments: a product name and a quantity to be purchased. This method throws an OutOfStockException if either the specified product is not available in the store or if the requested quantity is greater than the quantity available in stock. The method first…
- In the case that an exception is thrown outside of a try block, what kinds of outcomes are open to consideration?(a) Given the following method header: public boolean addMovie(Movie movie) Complete the implementation of the method above to insert a new movie into the Movies table in thedatabase. Your method should return true if an insert is successful, and false if an insert fails. You candetect a successful insert through the number of rows returned after the execution of a query. UsePreparedStatement in your answer and include the appropriate exception handling. The Movie classand database table structure specifications are shown in Figure 2.1 and Figure 2.2 below:True or False We can define a custom generic exception.
- in c++ Write a function named createOneStudent that will read in from the user the student info: id, name and gpa. It will use try-catch to handle the exception if the user provides a negative id or gpa that is out of bound (< 0.0 or > 4.0) by asking the user to re-enter them. It must provide the correct reason for the error and the actual error value. Then it will allow the user to try up to 3 times. This function will return the pointer of a newly created Student object or nullptr if the info is still incorrect. Note that this function can and will use cin and cout to read in values from the user. Here is an example of a run up to 3 times: Enter ID: -1 Enter GPA: 4.0 Enter name: John Smith Exception: negative id: -1 Enter ID: 1234 Enter GPA: 5.0 Enter name: John Smith Exception: out of bound gpa: 5.00 Enter ID: 1234 Enter GPA: 4.0 Enter name: John Smith ID(1234) NAME(John Smith) GPA(4.00) Here is an example of a run of 3 times and still not able to create it: Enter ID: 1234…Write a program that defines a class with a data member to holds a “serial number” for each object created from the class. That is, the first object created will be numbered 1, the second 2, and so on. To do this, you’ll need another data member that records a count of how many objects have been created so far. (This member should apply to the class as a whole; not to individual objects. What keyword specifies this?) Then, as each object is created, its constructor can examine this count member variable to determine the appropriate serial number for the new object. Add a member function that permits an object to report its own serial number. Then write a main() program that creates three objects and queries each about its serial number. They should respond I am object number 2, and so on. This question related to Object oriented programming in c++Write code for DivideByZero exception along with sample program using it.
