Question

create two subclasses called outpatient and inpatient which inherit from the patient base class

Answer 1

class Patient
{
    String First_Name;
    String Last_Name;
   String DOB;
   String Age;

Patient(String f_Name, String l_Name, String d, String ag)
{   
   First_Name = f_Name;
Last_Name = l_Name;
   DOB=d;
   Age=ag;
}

void Display()
{
System.out.println("First Name : " + First_Name);
System.out.println("Last Name : " + Last_Name);
   System.out.println("Date of Birth : " + DOB);
   System.out.println("Age : " + Age);
}
}

class OutPatient extends Patient
{
int id;
String Phone_Number;
String Doctor_name;

OutPatient(int i, String f_Name, String l_Name, String d,String ag, String ph, String dr )
{
super(f_Name,l_Name,d,ag);
id = i;
Phone_Number=ph;
Doctor_name = dr;
}
void Display()
{
super.Display();

System.out.println("ID : " + id);
System.out.println("Phone Number : " + Phone_Number);
System.out.println("Doctor Name : " + Doctor_Name);
}
}

class InPatient extends Patient
{
   String visitReason;
   String Admission_diagnosis;
   String Discharge_diagnosis;
   String Treatment;
   int Number_of_Days;

InPatient(String f_Name, String l_Name,String d, String ag, String reason, String a_dig, String d_dig, String treat,int days)
{
super(f_Name,l_Name,d,ag);
visitReason=reason;
       Admission_diagnosis=a_dig;
       Discharge_dignosis=d_dig;
       Treatment=treat;
       Number_of_Days=days;   
}
void Display()
{
super.Display();

System.out.println("visitReason : " + visitReason);
System.out.println("Admission diagnosis : " + Admission_diagnosis);
       System.out.println("Discharge diagnosis : " + Discharge_diagnosis);
System.out.println("Treatment : " + Treatment);
       System.out.println("Number of Days: " + Number_of_Days);
}
}
