Java深拷贝与浅拷贝

　　深拷贝与浅拷贝主要的不同是对于引用变量的拷贝，浅拷贝的引用变量不仅仅是拷贝一个引用(地址).引用变量的成员也一样深拷贝。废话少说下面是两个拷贝的例子

1.浅拷贝

package com.LightCopy;

public class Professor implements Cloneable{
    private String name;
    private int age;

    public String getName() {
        return name;
    }

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

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public Professor(String name, int age) {
        this.name = name;
        this.age = age;
    }
    
    @Override
    public Object clone()  {
         Professor o=null;    
            try    
             {    
                 o=(Professor) super.clone();    
             }    
            catch(CloneNotSupportedException e)    
             {    
                 e.printStackTrace();
             }  
            
            return o;    
         }    
    
}

2.深拷贝

package com.DeepCopy;

import com.LightCopy.Professor;

public class Student implements Cloneable {
    private String name;
    private int age;
    private Professor pro;
    public Professor getPro() {
        return pro;
    }

    public void setPro(Professor pro) {
        this.pro = pro;
    }

    public Student(String name, int age,Professor pro) {
        this.name = name;
        this.age = age;
        this.pro=pro;
    }

    public String getName() {
        return name;
    }

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

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    @Override
    public Object clone() {
        Student obj = null;
        try {
            obj = (Student) super.clone();
        } catch (CloneNotSupportedException ex) {
            ex.printStackTrace();
        }
        obj.pro=(Professor)pro.clone();
        return obj;
    }
}
