Java除了这两这种方法创建对象外，还有三个方式，使用new 关键字，使用对象克隆clone()方法，以及使用反序列化（ObjectInputStream）的 readObject() 方法。
使用 clone()方法：类必须实现Cloneable接口，并重写其clone()方法
使用反序列化ObjectInputStream 的readObject()方法：类必须实现 Serializable接口
```
public class Student implements Serializable,Cloneable{
private static final long serialVersionUID = -2263090506226622866L;
private String name;
@Override
protected Object clone() throws CloneNotSupportedException {
return super.clone();
}
@Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
Student student = (Student) o;
return name != null ? name.equals(student.name) : student.name == null;
}
@Override
public int hashCode() {
return name != null ? name.hashCode() : 0;
}
}
public class Client {
public static void main(String[] args) throws Exception {
//使用new关键字创建对象
Student student1 = new Student();
//使用clone()方法：类必须实现Cloneable接口，并重写其clone()方法
Student student2 = (Student) student1.clone();
// 使用 反序列化ObjectInputStream的readObject()方法：类必须实现 Serializable接口
// 序列化
ObjectOutputStream objectOutputStream = new ObjectOutputStream(new FileOutputStream("test.txt"));
objectOutputStream.writeObject(student1);
// 反序列化
ObjectInputStream objectInputStream = new ObjectInputStream(new FileInputStream("test.txt"));
Student student3 = (Student) objectInputStream.readObject();
}
}
```
记得之前写过一篇 单例模式 的博客，其中最后就提到序列化也会破坏单例，就是因为反序列化会创建新的对象，所以我们在单例模式中要有readResolve()方法。
