Pick your favorite geometry formula (example: area of a square, perimeter of a triangle and so on) and implement it in Java. Explain your code compiles and runs without issue (You can use screen captures to explain this functionality in a word document). Name your Java file Yournamehw1.java. Name your Word document Yournamehw1.doc (or Yournamehw1.docx).
Be sure to comprise comprehensive test cases to explain your formula is implemented correctly. Your test cases must comprise the input, expected output, actual output and if the test case passed or failed. You can document your test cases in a word table and comprise it in your word document submission. Use TDD (Test Driven Development) methods to make automated test(s) for your program.
