The Homework title is "Implement class for manipulating DNA sequence in plain format"

I'm stuck on this part of the coding question.

The first picture is where I should be writing the codes for the test code in picture 2

(It would be helpful if you explain your answer, since my teacher did not teach at all.)

Thank you

This week for our lab assignment we will use Test Driven Development. You will be given an interface file and a junit test file and a file containing dna sequence data. Your task is to write a class that implements the provided interface file and passes all tests in the provided junit test file. The class we will implement will read dna sequence information and store it into an object. Watch the video above and follow along on your own computer. The video walk through implementing some of the PlainSequences.java file to the point where 3 of the 4 unit tests pass, but you will still need to write your own code to get all 4 of the unit tests to pass. 1. Download these three files: Plain SequencesTest.java Sequences.java peptide mRNA.text 2 2. Place all three files into a new directory 3. Create a new java file in the same directory called PlainSequences.java 4. Create a Grasp project in that same directory and add to the project the three java files: Sequences.java, PlainSequences.java, and PlainSequencesTest.java 5. in the file PlainSequences.java write a class that implements the sequences.java interface. 6. Within your Grasp project run the tests in PlainSequencesTest.java 7. Repeat step 5 an 6 above until all 4 tests pass. 8. Submit via Canvas your completed PlainSequnces.java file that passes all 4 unit tests and a screen shot showing the junit test results by end of day Sunday January 24th. droBase - G Project Plainsequences - Plainsequences".
