Hibernate creates persistent class

A four-point principle of JavaBean

1. Must be a public class

2. Provide a public default constructor with no parameters

3. Property private

4. Property setter/getter encapsulation

 

 

2. Create a student persistence class

import java.util.Date;
//student class
public class Students {
        /*
