一个物业管理系统具体Java代码

以下是一个简单的物业管理系统的 Java 代码示例：

import java.util.Scanner;

public class PropertyManagementSystem {

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        Property[] properties = new Property[5];
        int count = 0;
        
        while (true) {
            System.out.println("请选择操作：");
            System.out.println("1. 添加物业");
            System.out.println("2. 显示所有物业");
            System.out.println("3. 搜索物业");
            System.out.println("4. 删除物业");
            System.out.println("5. 退出");
            
            int choice = scanner.nextInt();
            
            switch (choice) {
                case 1:
                    if (count < 5) {
                        System.out.println("请输入物业名称：");
                        String name = scanner.next();
                        System.out.println("请输入物业地址：");
                        String address = scanner.next();
                        System.out.println("请输入物业面积：");
                        double area = scanner.nextDouble();
                        properties[count] = new Property(name, address, area);
                        count++;
                        System.out.println("添加成功！");
                    } else {
                        System.out.println("物业数量已达上限！");
                    }
                    break;
                case 2:
                    if (count == 0) {
                        System.out.println("当前没有物业！");
                    } else {
                        for (int i = 0; i < count; i++) {
                            System.out.println(properties[i]);
                        }
                    }
                    break;
                case 3:
                    System.out.println("请输入搜索关键字：");
                    String keyword = scanner.next();
                    boolean found = false;
                    for (int i = 0; i < count; i++) {
                        if (properties[i].getName().contains(keyword) || properties[i].getAddress().contains(keyword)) {
                            System.out.println(properties[i]);
                            found = true;
                        }
                    }
                    if (!found) {
                        System.out.println("未找到符合条件的物业！");
                    }
                    break;
                case 4:
                    System.out.println("请输入要删除的物业名称：");
                    String name = scanner.next();
                    boolean deleted = false;
                    for (int i = 0; i < count; i++) {
                        if (properties[i].getName().equals(name)) {
                            for (int j = i; j < count - 1; j++) {
                                properties[j] = properties[j+1];
                            }
                            count--;
                            deleted = true;
                            System.out.println("删除成功！");
                            break;
                        }
                    }
                    if (!deleted) {
                        System.out.println("未找到要删除的物业！");
                    }
                    break;
                case 5:
                    System.out.println("感谢使用物业管理系统！");
                    System.exit(0);
                default:
                    System.out.println("无效的选择！");
                    break;
            }
        }
    }

}

class Property {
    private String name;
    private String address;
    private double area;
    
    public Property(String name, String address, double area) {
        this.name = name;
        this.address = address;
        this.area = area;
    }
    
    public String getName() {
        return name;
    }
    
    public String getAddress() {
        return address;
    }
    
    public double getArea() {
        return area;
    }
    
    public String toString() {
        return "名称：" + name + "，地址：" + address + "，面积：" + area;
    }
}

这个物业管理系统可以进行添加物业、显示所有物业、搜索物业和删除物业等操作。其中，使用 Property 类来表示一个物业，包含名称、地址和面积三个属性。在主函数中，使用一个 Property 数组来存储所有的物业，并且限制了最多只能添加五个物业。用户可以通过控制台输入来进行各种操作，如添加物业时需要输入物业名称、地址和面积，删除物业时需要输入要删除的物业名称等。
