18.1: Getting Even More Methodical

[(JAVA, ECLIPSE), Please keep the program as short as possible]

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