JAVA中的浅拷贝与深拷贝
浅拷贝：实现Clonenable接口并覆盖clone()方法
1 @Override
2 public Object clone() {
3 Student stu = null;
4 try{
5 stu = (Student)super.clone();
6 }catch(CloneNotSupportedException e) {
7 e.printStackTrace();
8 }
9 return stu;
10 }
深拷贝：
1 @Override
2 public Object clone() {
3 Student stu = null;
4 try{
5 stu = (Student)super.clone();
6 }catch(CloneNotSupportedException e) {
7 e.printStackTrace();
8 }
9 stu.addr = (Address)addr.clone(); //深度复制
10 return stu;
11 }
