Let’s make it so that we can look up and find a Procedure in the “Procedures.txt” file. The Procedures are organized by Procedure Code. So we should be able to look in the File for procedure “P114”, and it should give us back all the data about that procedure, like, Procedure Name, Price, etc. So we will need to read from the “Procedures.txt” file and select the Procedure code “P114”. The File is delimited by “:”(colons). Take a look at the file.

Code for testing ‘Select’ that goes in main:

         Procedure pr1 = new Procedure();

         pr1.select(“P114”);

         pr1.display();

Let’s also make it so that we can add a new Procedure to the “Procedures.txt” file. We should be able to append a new line to the “Procedures.txt” file with all the data for a new Procedure, like ProcedureCode, ProcedureName, etc.

Next do the same for the Patient class, the Dentist class and Appointment class.

Code for testing ‘Insert’ that goes in main:

         Procedure pr1 = new Procedure();

         pr1.insert(“P119”, “Polish”, “Polish Teeth”, 199.99);

         //now go look in file to see if new line was added
