Please written by computer source Implement try/except exception handler to catch all errors (from the following source code) separately: my_string = 'Hello World' print(my_string) num = int(my_string) print(my_string + 100) num = 1/0 print(total) print('Done') Submission Instructions: 1. Write all the code in one module (in one .py file), and save it as Firstname_Lastname_hw6.py (e.g., John Adam’s file name should be John_ Adam_hw6.py).
No restriction exists on the number of arguments permitted in a catch block.
Write code that would create and handle a Divide by Zero exception
-Modify your parameter constructors to call your set methods. This will cause validation of the parameter.-Create an exception class named TractorException.-Modify your setters to throw TractorException if invalid values are passed in. You may also need to add a throws clause to your parameter constructors. This way we will not have any print methods in our Tractor object defining class-Modify your main method to try and catch exceptions. It should catch TractorExceptions and general Exceptions and display an appropriate message import java.util.*; class TestException { public static void main(String s[]) { Scanner scanner = new Scanner(System.in); boolean valid=false; // validation loop while (!valid) { try { System.out.println("Enter integer:"); int number = scanner.nextInt(); // may throw an exception System.out.println("You entered "+ number); valid=true;…
What is a throw point? 2. What is an exception handler? 3. Explain the difference between a try block and a catch block. 4. What happens if an exception is thrown, but not caught? 5. Complete the following function that searches a numeric array for a specified value. The function should return the subscript of the element containing the value if it is found in the array. If the value is not found, the function should throw an exception. int searchArray(int array[], int size, int value){ int index = 0; // Used as an index to search array int subscript = -1; // To record position of search value while (index < size && subscript == -1) { if (array[index] == value) // If the value is found ___________________________________________________ ___________________________________________________ } if (subscript == -1) ___________________________________________________ return subscript; } Bonus…
What outcomes are possible in the event that an exception is thrown outside of a try block?
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…
