The __________ block should enclose code that directly or indirectly might cause an exception to be thrown.
1. Write an application that throws and catches an ArithmeticException when you attempt to take the
square root of a negative value. Prompt the user for an input value and try the Math.sqrt() method on
it. The application either displays the square root or catches the thrown Exception and displays an
appropriate message.

Again --Write a program that calculates an adult's fat-burning heart rate, which is 70% of 220 minus the person's age. Complete fat_burning_heart_rate() to calculate the fat burning heart rate. The adult's age must be between the ages of 18 and 75 inclusive. If the age entered is not in this range, raise a ValueError exception in get_age() with the message "Invalid age." Handle the exception in __main__ and print the ValueError message along with "Could not calculate heart rate info." Ex: If the input is: 35 the output is: Fat burning heart rate for a 35 year-old: 129.5 bpm If the input is: 17 the output is: Invalid age.

In thisassignment, you will write a program for .edu email address validation system. Problem Design: The program will take an email address from user and check if it contains thefollowing:a. Address must contain at least an ‘@’ symbolb. Address must contain at least a ‘.edu’ suffixc. Length must contain at least 12 characters.d. Address must contain at least one digit 2. Helper functions to check if an address has at least one digit is provided. Docstring arealso given in the template file. This function returns True if condition satisfies otherwisereturns False. 3. Your task: Design a base class (Invalid Address) and child exception classes(InsufficientLength, NoDigit, NoEdu, NoAtSymbol ) to raise the exception when theconditions are not met. 4. Design a simple user menu to ask for the address as long as the user does not enter a validaddress. 5.
