用java编写详细代码：一个客户信息管理系统，包含个人客户（ IndividualCustomer）和企业客户（InstitutionalCustomer）两类信息并储存在某类集合中,主函数 编写向系统中添加客户（addCustomer）的方法，并从键盘输入具体客户的信息（要求 包括个人客户和企业客户）保存在某类集合（具体集合类自己选择）。 （4）编写从系统中输出客户（printCustomer）的方法，应用多态编程输出所有具体客户的信息。

好的，以下是Java代码：

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

class Customer {
    private String name;
    private String address;
    private String phoneNumber;
    private String email;

    // 构造方法
    public Customer(String name, String address, String phoneNumber, String email) {
        this.name = name;
        this.address = address;
        this.phoneNumber = phoneNumber;
        this.email = email;
    }

    // getter 和 setter 方法
    public String getName() {
        return name;
    }

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

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public String getPhoneNumber() {
        return phoneNumber;
    }

    public void setPhoneNumber(String phoneNumber) {
        this.phoneNumber = phoneNumber;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    // toString 方法
    public String toString() {
        return "Name: " + name + "\nAddress: " + address + "\nPhone Number: " + phoneNumber + "\nEmail: " + email;
    }
}

class IndividualCustomer extends Customer {
    private String idNumber;

    // 构造方法
    public IndividualCustomer(String name, String address, String phoneNumber, String email, String idNumber) {
        super(name, address, phoneNumber, email);
        this.idNumber = idNumber;
    }

    // getter 和 setter 方法
    public String getIdNumber() {
        return idNumber;
    }

    public void setIdNumber(String idNumber) {
        this.idNumber = idNumber;
    }

    // toString 方法
    public String toString() {
        return super.toString() + "\nID Number: " + idNumber;
    }
}

class InstitutionalCustomer extends Customer {
    private String taxIdNumber;

    // 构造方法
    public InstitutionalCustomer(String name, String address, String phoneNumber, String email, String taxIdNumber) {
        super(name, address, phoneNumber, email);
        this.taxIdNumber = taxIdNumber;
    }

    // getter 和 setter 方法
    public String getTaxIdNumber() {
        return taxIdNumber;
    }

    public void setTaxIdNumber(String taxIdNumber) {
        this.taxIdNumber = taxIdNumber;
    }

    // toString 方法
    public String toString() {
        return super.toString() + "\nTax ID Number: " + taxIdNumber;
    }
}

public class CustomerManagementSystem {
    private ArrayList<Customer> customers = new ArrayList<Customer>();

    // 添加客户
    public void addCustomer(Customer customer) {
        customers.add(customer);
    }

    // 输出客户信息
    public void printCustomers() {
        for (Customer customer : customers) {
            System.out.println(customer.toString());
            System.out.println();
        }
    }

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

        CustomerManagementSystem system = new CustomerManagementSystem();

        System.out.println("Enter customer information:");

        // 添加个人客户
        System.out.print("Name: ");
        String name = scanner.nextLine();
        System.out.print("Address: ");
        String address = scanner.nextLine();
        System.out.print("Phone Number: ");
        String phoneNumber = scanner.nextLine();
        System.out.print("Email: ");
        String email = scanner.nextLine();
        System.out.print("ID Number: ");
        String idNumber = scanner.nextLine();

        IndividualCustomer individualCustomer = new IndividualCustomer(name, address, phoneNumber, email, idNumber);
        system.addCustomer(individualCustomer);

        // 添加企业客户
        System.out.print("Name: ");
        name = scanner.nextLine();
        System.out.print("Address: ");
        address = scanner.nextLine();
        System.out.print("Phone Number: ");
        phoneNumber = scanner.nextLine();
        System.out.print("Email: ");
        email = scanner.nextLine();
        System.out.print("Tax ID Number: ");
        String taxIdNumber = scanner.nextLine();

        InstitutionalCustomer institutionalCustomer = new InstitutionalCustomer(name, address, phoneNumber, email, taxIdNumber);
        system.addCustomer(institutionalCustomer);

        // 输出客户信息
        system.printCustomers();
    }
}

这个客户信息管理系统使用了面向对象的编程思想，将客户抽象出来成为一个类，然后派生出个人客户和企业客户两个子类，通过多态来统一处理不同类型的客户。在主函数中，通过输入来创建客户对象，并将其添加到集合中，最后输出所有客户的信息。
