Let’s make it so that we can look up and find a Patient in the “Patients.txt” file. The Patients are organized by Patients Code. So we should be able to look in the File for Patient “A900”, and it should give us back all the data about that Patient, like, Patinet Id, etc. So we will need to read from the “Patients.txt” file and select the Patient Id “A900”. The File is delimited by “:”(colons). Take a look at the file. use FileInputStream and Buffered reader to read from the file.
Code for testing ‘Select’ that goes in main:
Patient p1 = new Patient();
p1.select(“A900”);
p1.display();
Let’s also make it so that we can add a new Patient to the “Patients.txt” file.use PrintStream and Buffered writer to write to the file. We should be able to append a new line to the “Patients.txt” file with all the data for a new Patient, like PatientId,etc.
Code for testing ‘Insert’ that goes in main:
Patient p1 = new Patient();
p1.insert(“A900\",\"1234\",\"Jimmy:Hawkins\",\"Marietta\",\"jhawk@yahoo.com\",\"Cigna\");
//now go look in file to see if new line was added
