Hi Everyone I am newbie to hibernate i have small doubt

For Example ,

I have Entity Employee..
@Entity
@Table(name="Employee")
Employee(){
@id
@Column(name="employeeID",unique=true, nullable=false)
int id;
@Column(name="employeeName",unique=false, nullable=true)
String Name;
@Column(name="employeeAge",unique=false, nullable=true)
int age;
...
....
}

consider everything configured properely for entity

when i am fetching Employee object from table if age value is null;

In Employee entity (int age) is an primitive type. how it will map ....

You will get a NullPointerException if the value in the database is null. To fix it, you'll need to make sure all values are non-null or use an Integer instead of an int in your code.
