Created By: Geoffrey Challen

/ Version: 2021.10.0

Declare a public class BothWays providing one static method create. create takes a single String parameter and returns an anonymous object that implements the IBothWays interface:

So, for example:

If the String passed to create is null, throw an IllegalArgumentException.

Test Design Challenge

You're challenge is to write tests for this problem described above.

• Provide a public class named TestBothWays with a single non-private class method named test that accepts no arguments and does not return a value.
• If the implementation of the class described above is incorrect, your test method should throw an exception.
• If it is correct, do not throw an exception.
• You may want to use Java's assert method
