Overloaded Constructor Not Being Implemented?

For some reason, even though I am giving it the correct number of arguments for the constructor to be initalized it doesn't go through. I end up with a compile error:

PatientBuilder.java:17: error:

constructor Patient in class Patient cannot be applied to given types;
Patient aPatient = new Patient(bloodType, rhFactor, ID, age);
^
required: no arguments
found: String,String,int,int
reason: actual and formal argument lists differ in length

And I'm not understanding how that's possible when it calls for 2 strings and 2 ints and that's what I am passing.

I have this in my main method Scanner inputDevice = new Scanner(System.in);

System.out.println("What is the patients ID number?");
int ID = inputDevice.nextInt();
System.out.println("What is the patients age?");
int age = inputDevice.nextInt();

[Code] ....

And then here are my two constructors, one default and one overloaded.

public Patient() {
patientBlood = new BloodData();
ID = 0;
age = 0;
bloodType = "O";
rhFactor = "+";
