Java program for a hospital management system
Here's a simple Java program for a hospital management system:
```
import java.util.ArrayList;
import java.util.Scanner;
class Patient {
private String name;
private int age;
private String disease;
private String doctor;
public Patient(String name, int age, String disease, String doctor) {
this.name = name;
this.age = age;
this.disease = disease;
this.doctor = doctor;
}
public String getName() {
return name;
}
public int getAge() {
return age;
}
public String getDisease() {
return disease;
}
public String getDoctor() {
return doctor;
}
}
class Doctor {
private String name;
private String specialization;
public Doctor(String name, String specialization) {
this.name = name;
this.specialization = specialization;
}
public String getName() {
return name;
}
public String getSpecialization() {
return specialization;
}
}
public class HospitalManagement {
private ArrayList<Patient> patients;
private ArrayList<Doctor> doctors;
private Scanner scanner;
public HospitalManagement() {
patients = new ArrayList<>();
doctors = new ArrayList<>();
scanner = new Scanner(System.in);
}
public void addPatient() {
System.out.print("Enter patient name: ");
String name = scanner.nextLine();
System.out.print("Enter patient age: ");
int age = scanner.nextInt();
scanner.nextLine(); // Consume newline left-over
System.out.print("Enter patient disease: ");
String disease = scanner.nextLine();
System.out.print("Enter doctor's name: ");
String doctorName = scanner.nextLine();
patients.add(new Patient(name, age, disease, doctorName));
}
public void addDoctor() {
System.out.print("Enter doctor's name: ");
String name = scanner.nextLine();
System.out.print("Enter doctor's specialization: ");
String specialization = scanner.nextLine();
doctors.add(new Doctor(name, specialization));
}
public void displayPatients() {
System.out.println("\nPatient List:");
for (Patient patient : patients) {
System.out.println("Name: " + patient.getName());
System.out.println("Age: " + patient.getAge());
System.out.println("Disease: " + patient.getDisease());
System.out.println("Doctor: " + patient.getDoctor());
System.out.println();
}
}
public void displayDoctors() {
System.out.println("\nDoctor List:");
for (Doctor doctor : doctors) {
System.out.println("Name: " + doctor.getName());
System.out.println("Specialization: " + doctor.getSpecialization());
System.out.println();
}
}
public void run() {
while (true) {
System.out.println("\nHospital Management System");
System.out.println("1. Add Patient");
System.out.println("2. Add Doctor");
System.out.println("3. Display Patients");
System.out.println("4. Display Doctors");
System.out.println("5. Exit");
System.out.print("Enter your choice: ");
int choice = scanner.nextInt();
scanner.nextLine(); // Consume newline left-over
switch (choice) {
case 1:
addPatient();
break;
case 2:
addDoctor();
break;
case 3:
displayPatients();
break;
case 4:
displayDoctors();
break;
case 5:
System.exit(0);
break;
default:
System.out.println("Invalid choice. Please try again.");
}
}
}
public static void main(String[] args) {
HospitalManagement management = new HospitalManagement();
management.run();
}
}
```
*Example Output:*
```

This program defines three classes: `Patient`, `Doctor`, and `HospitalManagement`. The `Patient` class has private member variables for patient details and public methods for accessing those details. The `Doctor` class has private member variables for doctor details and public methods for accessing those details. The `HospitalManagement` class has private member variables for patient and doctor lists, as well as public methods for adding patients and doctors,
