

Create Model

Patient.java public class Patient { private int refNo; private String name;

//enter get and set methods for the attributes }

Patient.java (Solutions) public class Patient { private int refNo; private String name;

public int getRefNo() { return refNo; }

public void setRefNo(int no) { this.refNo = no; }

public String getName() { return name; }

public void setName(String aName) { this.name = aName; } }



Create View

PatientView.java public class PatientView { public void displayPatientDetails(String name, int ref){ System.out.println("Patient: "); System.out.println("Name: " + name); System.out.println("Ref No: " + ref); } }



Create Controller

PatientController.java public class PatientController { //add attributes required – pat for a Patient Object and view for a PatientView object //enter you code here

public PatientController(Patient aPat, PatientView aView){ //enter your code here

} public void setPatientName(String name){ pat.setName(name); } public String getPatientName(){ return pat.getName(); } public void setPatientNo(int no){ pat.setRefNo(no); } public int getPatientNo(){ return pat.getRefNo(); } public void updateView(){ view.displayPatientDetails(pat.getName(),pat.getRefNo()); } }

PatientController.java (Solutions) public class PatientController { //add attributes required – pat for a Patient Object and view for a PatientView object private Patient pat; private PatientView view;

public PatientController(Patient aPat, PatientView aView){ this.pat = aPat; this.view = aView; } public void setPatientName(String name){ pat.setName(name); } public String getPatientName(){ return pat.getName(); } public void setPatientNo(int no){ pat.setRefNo(no); } public int getPatientNo(){ return pat.getRefNo(); } public void updateView(){ view.displayPatientDetails(pat.getName(),pat.getRefNo()); } }
