Question $1$

Create your own IllegalDivisorException class. Make it a checked exception. Throw it from

a divide$($int numerator, int denominator$)$ method from a Math class. From a main$()$ method

in the same class, divide $5$ by $2$ and print the result $"5$ divided by $2$ is $2\mathrm{.}5"$ by using your

divide method. Also from the main$()$ method call divide$(5,0)$ and see the error displayed.

Question $4$

Create your OWN jUnit test cases, for all positive and negative scenarios, and then write code

to pass it$.$ A test case should test just one scenario.

Here are the requirements:

Class Name has two instance variables: first and last. The constructor throws

IllegalArgumentExceptions if either is null. The getName$()$ method returns the first and last

names in Title Case, concatenated with a space between $("$tiger$",$ "woods" becomes "Tiger

Woods"$).$ Test all this. Pass your own tests.
