java 复制代码

public class WorkExperience implements Cloneable {
    private String workDate;
    private String company;

    public void setWorkDate(String workDate) {
        this.workDate = workDate;
    }

    public void setCompany(String company) {
        this.company = company;
    }

    @Override
    public Object clone() throws CloneNotSupportedException {
        WorkExperience obj = new WorkExperience();
        obj.workDate = this.workDate;
        obj.company = this.company;
        return obj;
    }

    @Override
    public String toString() {
        return "WorkExperience{" +
                "workDate='" + workDate + '\'' +
                ", company='" + company + '\'' +
                '}';
    }

简历类

java 复制代码

public class Resume implements Cloneable {
    private String name;
    private String sex;
    private String age;
    private WorkExperience work;

    public Resume(String name) {
        this.name = name;
        work = new WorkExperience();
    }

    private Resume(WorkExperience work) throws CloneNotSupportedException {
        this.work = (WorkExperience) work.clone();
    }

    public void setPersonInfo(String sex, String age) {
        this.sex = sex;
        this.age = age;
    }

    public void setWorkExperience(String workDate, String company) {
        work.setWorkDate(workDate);
        work.setCompany(company);
    }


    @Override

        obj.name = name;
        obj.sex = sex;
        obj.age = age;
        return obj;
    }

    @Override
    public String toString() {

演示类

java 复制代码

public class WorkResume {
    public static void main(String[] args) throws CloneNotSupportedException {
        Resume a = new Resume("张三");
        a.setPersonInfo("男","29");
        a.setWorkExperience("1998~2000","XXX公司");
        System.out.println(a);
        Resume b= (Resume) a.clone();
        b.setWorkExperience("2001~2006","YYY公司");
        System.out.println(b);
