Given 2 Strings, first and second, return a new String made of the first character of first and the last character of second. So "yo" and "java" yields "ya". If either string is length 0, use '@' for its missing char.

Test Design Challenge

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

• Provide a 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
