A Chinese restaurant wants to have a computer-based search system that will display a recipe for each dish. The owner of the restaurant wants the system to be flexible in that its recipes are stored in a text file. This way, the number of dishes can be expanded by adding more entries to the text file without changing any program code.

After analyzing the coding the restaurant realizes that Current coding only outputs first two line of the recipe.

Goal: Correct/debug RecipeFinder class to have the full recipe description in the output console in eclipse rather than having only first two lines. Other features should remain the same.

Requirements

To get full credit, you must follow the requirements specified below:

1. Particularly, you cannot use the Scanner class to read data from the keyboard or from a file. Instead, you should use BufferedReader, FileReader, InputStreamReader.

2. Your code must match your design (the class diagram). This includes the number of classes; the methods inside classes; and the relationships among these classes.

3. Put the unreliable code into Javas Exception management system (proper use of try-catch construct).

4. Must use automatic file closing feature.

Implementation

Create the text recipefile.txt and save it to C:/tmp/ directory.

Edit the work class RecipeFinder inside the project. This is the most difficult class in this program. One thing you need to figure out is how to output the whole body of a recipe based on the specific knowledge of when there is an empty line between the current recipe and the one following it. To help you, I offer the following segment of code (you are not required to use it) for you to use:

do {

info = br.readLine();

if(info != null) System.out.println(info);

} while((info != null) && (info.trim().compareTo( ) != 0));

return true;

DO THE FOLLOWING TO SCORE YOUR POINTS

- Draw a class diagram in the space below (name your work class RecipeFinder; the application class TestRecipeFinder):

- Paste your source code in the space below (make sure that your code works appropriately, the source code format conforms to Java conventions (with appropriate indentations, you may lose points for not indent appropriately)):

-Test your code

Start afresh.

Type the recipe name roast fish.

Type stop.

Do a screen capture of the output.

Here is the content of the recipefile.txt in C:/tmp/ directory.

#appetizers

vegetable, egg roll, mixed with cream cheese, add some Teriyaki chicken, half gallon of water. Cook 15 minutes.

#chow mein

white meat chicken, pork beef, shrimp, vegetable include greens, mushroom, carrots, banana, apple source, half gallon of water. Cook 15 minutes.

#fried rice

plain rice, pork, chicken, beef, shrimp, vegetable, vegetable, include greens, mushroom, carrots, banana, apple source, one ounce of vegetable oil. Add the oil to a wok first, using hot fire to cook the oil to hot and able to see slight smoke. Then add all the ingredients and mix them. Cook 15 minutes.

#poultry dish

Moo Goo Gai Pan, Chicken with Mushroom, Chicken with Black Bean Source, Chicken with Oyster Source, Curry Chicken with onion, Chicken with Pepper & Tomato, Chicken with Broccoli, Chicken with Mixed Vegetable, Sweet & Sour Chicken, Chicken with Garlic Source, Hunan Chicken, Szechuan Chicken.
