Create a new Java file and: 1. Create an exception class named NegativeNumberException extended from the class
Exception. This class should contain a parameterless constructor to call the Exception
class constructor with the message “You should enter a positive number”.
2. Create a class named exercise3 that contains:
a) A method named M1 that accepts a double variable as argument and returns
its square root. The method should throw the NegativeNumberException
exception defined above.
b) The main method to prompt the user to enter a number and then to call the
method M1 (insert a try-catch block to handle the NegativeNumberException
exception)
