原型模式Prototype：用原型实例指定创建对象的种类，并通过拷贝这些原型创建新的对象

例子：进行简历复制

先建立一个工作经历类

package Prototype;public class WorkExperience implements Cloneable{	public String workDate;	public String company;	public String getWorkDate() {		return workDate;	}	public void setWorkDate(String workDate) {		this.workDate = workDate;	}	public String getCompany() {		return company;	}	public void setCompany(String company) {		this.company = company;	}		public Object clone() throws CloneNotSupportedException{		return super.clone();	}	}

简历类

package Prototype;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();	}	public Resume(WorkExperience work) throws CloneNotSupportedException{		this.work=(WorkExperience)work.clone();	}	public void setPersonalInfo(String sex,String age){		this.sex=sex;		this.age=age;	}		public void setWorkExperience(String workDate,String company){		work.workDate=workDate;		work.company=company;	}	public void dispany(){		System.out.println(name+" "+sex+" "+age);		System.out.println(work.workDate+" "+work.company);	}	public Object Clone() throws CloneNotSupportedException{		Resume obj=new Resume(this.work);		obj.name=this.name;		obj.sex=this.sex;		obj.age=this.age;		return obj;	}	}

进行测试，clone两个人

package Prototype;public class Test {	public static void main(String[] args) throws CloneNotSupportedException {		// TODO Auto-generated method stub		Resume a=new Resume("Autumn");		a.setPersonalInfo("woman","18");		a.setWorkExperience("1998--2008", "ali");				Resume b=(Resume)a.Clone();		b.setWorkExperience("1998--2000", "tenxun");				Resume c=(Resume)a.Clone();		c.setWorkExperience("1998--2020", "huawei");		c.setPersonalInfo("man","88");				a.dispany();		b.dispany();		c.dispany();	}}

结果如下，可见，无论是修改值类型还是引用类型，都为对克隆体即原型产生影响

Autumn woman 181998--2008 aliAutumn woman 181998--2000 tenxunAutumn man 881998--2020 huawei
