• Copy and paste the starter code into a new file called Methodical.java

• Write the required methods as described by the comments (i.e. you fill in the body of

the method).

• Then, run the code when you are finished to see if you wrote the methods correctly.

• Check the test results and make any alterations to your methods as necessary.

• When all of the tests pass, upload your code to Canvas.
