Unable to add valid if statement to method

[Emma Lucy]

Hi,
When the printPatientList method is called, all the details for the patients in the patientList array are displayed, but I am unable to add a valid if statement to say if no patients are in the array, println("No patients registered"). Code below:

public void printPatientList() 
{ 
System.out.println("Patients currently registered:");
for (int i=0; i<numPatients; i++) 
patientList[i].printDetails(); //prints array contents 
}

Any suggestions most gratefully received.

What's wrong with

if (numPatients == 0)
  System.out.println("I'm out of patients...");

I see your for loop does not have {}'s
May be you are adding the if statement in the wrong place. Add curly braces to the for loop, and then add your if, so you'll see where everything goes.

Thanks Ernest, that works brilliantly. I'm a real newbie - doh!
