Java SE 6 validating Required data elements

[duane skey]

I need help Validating the required data elements in this program. I need the Patient id,Patient last name Patient first name, Patient primary care physician, Patient address1,Patient city, Patient State, Patient zip. all validated (entered as non-spaces) If invalid data is ,entered, display an "invalid input of type .. Record reject" message and use the COUNTINUE statement to return to the top of the loop to allow a new entry to be made.

  import java.util.Scanner;
 
public class medrecord {
 
	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Scanner string = new Scanner (System.in);
		String choice="y";
		while(choice.equalsIgnoreCase("y"))
		{
		System.out.println("Welcome to Medical Record Program");
		
		System.out.println(); //insert a blank line
		
		//enter patient information 
		
		System.out.println("Patient ID?");
		String id = string.nextLine();
		
		System.out.println("Patient Last Name?");
		String name = string.nextLine();
 
		System.out.println("Patient First Name?");
		String name2 = string.nextLine();
				
		System.out.println("Patient Middle Name?");
		String name3 = string.nextLine();
 
		System.out.println("Patient Date of Birth?");
		String dob = string.nextLine();
		
		System.out.println("Patient SSN #?");
		String ssn = string.nextLine();
 
		System.out.println("Patient Address 1?");
		String adress = string.nextLine();
 
		System.out.println("Patient Address 2?");
		String adress2 = string.nextLine();
 
		System.out.println("Patient City?");
		String city = string.nextLine();
 
		System.out.println("Patient State?");
		String state = string.nextLine();
 
		System.out.println("Patient Zip code?");
		String zip = string.nextLine();
 
		System.out.println("Patient Primary Care Physician?");
		String pricrphy = string.nextLine();
		
		System.out.println("Patient primary insurance compay?");
		String insur = string.nextLine();
 
		System.out.println("Patient primary insurance ID?");
		String insid = string.nextLine();
 
		System.out.println("Patient secoundary insurance compay?");
		String insur2 = string.nextLine();
 
		System.out.println("Patient secoundary insurance ID?");
		String insid2 = string.nextLine();
 
		System.out.println("Patient next of kin emergancy contact?");
		String emrcont = string.nextLine();
 
		System.out.println("Patient home phone number?");
		String numres = string.nextLine();
 
		System.out.println("Patient work number?");
		String numwrk = string.nextLine();
 
		System.out.println("Patient cell phone number?");
		String numcel = string.nextLine();
		
		
		System.out.println(); //insert a blank line
 
		System.out.println("Patient ID: " + id);
		System.out.println("Last Name: " + name);
		System.out.println("First Name: " + name2);
		System.out.println("MI: " + name3);
		System.out.println("Date Of Birth: " + dob);
		System.out.println("SSN: " + ssn);
		System.out.println("Address: " + adress);
		System.out.println("Address 2: " + adress2);
		System.out.println("City: " + city);
		System.out.println("State: " + state);
		System.out.println("Zip Code: " + zip);
		System.out.println("Patient Primary Care Physician: " + pricrphy);
		System.out.println("Patient Primary Insurance Company: " + insur);
		System.out.println("Patient Primary Insurance ID: " + insid);
		System.out.println("Patient Secoundary Insurance Company: " + insur2);
		System.out.println("Patient Secoundary Insurance ID: " + insid2);
		System.out.println("Emergancy Contact: " + emrcont);
		System.out.println("Residential phone number: " + numres);
		System.out.println("Work phone number: " + numwrk);
		System.out.println("Cellular phone number: " + numcel);
		System.out.print("Coutinue ? (y/n):");

Check out Scanner's other methods, like nextInt(). Also, use the hasNextXXX methods to check if data is available. For instance:

System.out.println("Patient ID?");
String id = (string.hasNextLine() ? string.nextLine() : null);
if (id == null || <id is invalid>)
{
    System.out.println("Invalid Patient ID: " + id);
    choice = "y";
    continue;
}
// other fields similarly

To make sure your code remains readable, you can create one method for each different type of validation.

inserted the code into the program and this is the error
recieved this Error on This line
if (id == null || <id is invalid>);
Multiple markers at this line

- Syntax error on token "is", , expected
- String literal is not properly closed by a
double-quote
- Syntax error on token(s), misplaced construct
(s)
- Syntax error on tokens, delete these tokens

The <id is invalid> is pseudo code. You should fill that in yourself, based on the logic of when an ID is invalid. As I said, you could create a method "boolean isValidPatientID(String id)", then change the if to

if (id == null || !isValidPatientID(id))
