Duke University — Java Programming: Solving Problems with Software — Week 3

The third week of this course has been quite enjoyable. I, personally, have an interest in data science, and this week delivers an introduction to reading CSV files in a major way. Even though I have taken an introduction to data science already, through the University of Michigan, I still learned plenty of new material.

In this week, we learned the methods associated with CSVs, as well as what methods would need to be imported from the java.io.* library. We used CSV files related to weather patterns in Raleigh, North Carolina in order to discern key bits of information. This week made it necessary for you to follow through on the seven step method in order to write a correct and complete program.

The seven step method is as follows:

1. ) Work Example By Hand
2. ) Write Down What You Did
3. ) Find Patterns
4. ) Check By Hand
5. ) Translate To Code
6. ) Run Test Cases
7. ) Debug Failed Test Cases

This method has become essential for me to solve programming exercises.

I now look forward to week 4!
