我有一个商机他有123456 共6个状态分别代表线索、提供简历、面试通过、人员驻场、合同评审、合同归档。请你设计一个请用java写出商机从线索到归档的整个流程流转过程

1. 首先创建一个枚举类，包含6个状态：

public enum BusinessStatus {
    LEAD,
    RESUME_PROVIDED,
    INTERVIEW_PASSED,
    ON_SITE,
    CONTRACT_REVIEWED,
    CONTRACT_ARCHIVED
}

2. 然后创建一个商机类，包含商机的基本信息和当前状态：

public class Business {
    private String name;
    private String description;
    private BusinessStatus status;

    // getters and setters
}

3. 在商机类中添加一个方法，用于更新商机的状态：

public void updateStatus(BusinessStatus newStatus) {
    // 检查状态是否合法
    if (newStatus.ordinal() - this.status.ordinal() != 1) {
        throw new IllegalArgumentException("Invalid status transition.");
    }

    // 更新状态
    this.status = newStatus;
}

4. 最后，编写一个测试类，模拟商机的整个流程流转过程：

public class BusinessProcess {
    public static void main(String[] args) {
        // 创建一个新的商机
        Business business = new Business();
        business.setName("ABC");
        business.setDescription("This is a new business.");

        // 商机从线索状态开始
        business.updateStatus(BusinessStatus.LEAD);
        System.out.println("Business status: " + business.getStatus());

        // 提供简历
        business.updateStatus(BusinessStatus.RESUME_PROVIDED);
        System.out.println("Business status: " + business.getStatus());

        // 面试通过
        business.updateStatus(BusinessStatus.INTERVIEW_PASSED);
        System.out.println("Business status: " + business.getStatus());

        // 人员驻场
        business.updateStatus(BusinessStatus.ON_SITE);
        System.out.println("Business status: " + business.getStatus());

        // 合同评审
        business.updateStatus(BusinessStatus.CONTRACT_REVIEWED);
        System.out.println("Business status: " + business.getStatus());

        // 合同归档
        business.updateStatus(BusinessStatus.CONTRACT_ARCHIVED);
        System.out.println("Business status: " + business.getStatus());
    }
}

输出结果：

Business status: LEAD
Business status: RESUME_PROVIDED
Business status: INTERVIEW_PASSED
Business status: ON_SITE
Business status: CONTRACT_REVIEWED
Business status: CONTRACT_ARCHIVED
