很抱歉,我无法直接提供完整的客户关系管理系统的Java代码,因为它通常需要根据特定的需求和业务逻辑进行定制开发。但是,我可以提供一个简单的示例代码,展示如何构建一个基本的客户关系管理系统。以下是一个简单的示例:
```java
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;
class Customer {
private String name;
private String email;
public Customer(String name, String email) {
this.name = name;
this.email = email;
}
public String getName() {
return name;
}
public String getEmail() {
return email;
}
}
class CustomerManagementSystem {
private List<Customer> customers;
public CustomerManagementSystem() {
customers = new ArrayList<>();
}
public void addCustomer(Customer customer) {
customers.add(customer);
System.out.println("Customer added: " + customer.getName());
}
public void removeCustomer(Customer customer) {
customers.remove(customer);
System.out.println("Customer removed: " + customer.getName());
}
public void displayAllCustomers() {
for (Customer customer : customers) {
System.out.println("Name: " + customer.getName() + ", Email: " + customer.getEmail());
}
}
}
public class Main {
public static void main(String[] args) {
CustomerManagementSystem cms = new CustomerManagementSystem();
Scanner scanner = new Scanner(System.in);
while (true) {
System.out.println("1. Add Customer");
System.out.println("2. Remove Customer");
System.out.println("3. Display All Customers");
System.out.println("4. Exit");
System.out.println("Please enter your choice:");
int choice = scanner.nextInt();
scanner.nextLine(); // Consume newline character
switch (choice) {
case 1:
System.out.println("Enter customer name:");
String name = scanner.nextLine();
System.out.println("Enter customer email:");
String email = scanner.nextLine();
Customer customer = new Customer(name, email);
cms.addCustomer(customer);
break;
case 2:
System.out.println("Enter customer name to remove:");
String nameToRemove = scanner.nextLine();
Customer customerToRemove = null;
for (Customer c : cms.customers) {
if (c.getName().equalsIgnoreCase(nameToRemove)) {
customerToRemove = c;
break;
}
}
if (customerToRemove != null) {
cms.removeCustomer(customerToRemove);
} else {
System.out.println("Customer not found!");
}
break;
case 3:
cms.displayAllCustomers();
break;
case 4:
System.out.println("Exiting...");
System.exit(0);
break;
default:
System.out.println("Invalid choice!");
}
}
}
}
```
这只是一个简单的示例,实际的客户关系管理系统可能包含更多功能和复杂的业务逻辑。你可以根据自己的需求来扩展和定制这个示例代码。希望对你有所帮助!
