- [Instructor] Now that we have created a dummy recipe,…let's use test-driven development to parse out as fields.…Go back to ReceiptTest.…We are going to enter another red/green/refactor cycle.…We will want to know that the id is what we expected.…Take a look at the text file.…The id should be water.…Go back to the test and add the line…assertEquals("water", recipe.id).…
Run the test, again, it fails,…because we are in the red part…of the red/green/refactor cycle.…So let's go to the recipe and actually implement…the part where we parse out the id.…To do that, we will need to create a BufferedReader…out of the InputStream.…BufferedReader, we'll call it reader, = new BufferedReader,…and then inside we'll have a new InputStreamReader,…which we'll give it stream.…
Next, we are going to read out of this reader line by line.…For (String line = reader.readLine(); line != null;…line = reader.readLine().…You can see that the reader reader.readLine…has exception, so we'll wrap the whole thing…in a Try/Catch block.…Try, catch (IOException e).…
