药品信息管理java代码

药品信息管理是一个常见的管理系统，可以使用Java编程语言来实现。以下是一个简单的药品信息管理系统的Java代码示例：

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

class Drug {
    private String name;
    private String manufacturer;
    private double price;

    public Drug(String name, String manufacturer, double price) {
        this.name = name;
        this.manufacturer = manufacturer;
        this.price = price;
    }

    public String getName() {
        return name;
    }

    public String getManufacturer() {
        return manufacturer;
    }

    public double getPrice() {
        return price;
    }
}

class DrugManagementSystem {
    private List<Drug> drugList;

    public DrugManagementSystem() {
        drugList = new ArrayList<>();
    }

    public void addDrug(Drug drug) {
        drugList.add(drug);
    }

    public void displayDrugs() {
        for (Drug drug : drugList) {
            System.out.println("Name: " + drug.getName());
            System.out.println("Manufacturer: " + drug.getManufacturer());
            System.out.println("Price: " + drug.getPrice());
            System.out.println("--");
        }
    }
}

public class Main {
    public static void main(String[] args) {
        DrugManagementSystem system = new DrugManagementSystem();
        Scanner scanner = new Scanner(System.in);

        while (true) {
            System.out.println("1. Add drug");
            System.out.println("2. Display drugs");
            System.out.println("3. Exit");
            System.out.print("Enter your choice: ");
            int choice = scanner.nextInt();

            if (choice == 1) {
                System.out.print("Enter drug name: ");
                String name = scanner.next();
                System.out.print("Enter manufacturer: ");
                String manufacturer = scanner.next();
                System.out.print("Enter price: ");
                double price = scanner.nextDouble();

                Drug drug = new Drug(name, manufacturer, price);
                system.addDrug(drug);
                System.out.println("Drug added successfully!");
            } else if (choice == 2) {
                system.displayDrugs();
            } else if (choice == 3) {
                break;
            } else {
                System.out.println("Invalid choice! Please try again.");
            }
        }

        scanner.close();
    }
}

这段代码实现了一个简单的药品信息管理系统。用户可以选择添加药品、显示药品列表或退出程序。每个药品有名称、生产商和价格属性。用户可以通过输入相关信息来添加药品，并可以查看已添加的药品列表。
