How do we read an object in java which is stored in mysql as Blob data type?
MySql Table stored classes Object, like
Class Student implements Serialized{
int roll;
String name;
String course;
Student(int roll, String course, String name)
{
this.roll=roll;
this.name=name;
this.course=course;
}
}
we creat the object of class
Student stud=new Student(1."ram","Java");
Mysql database table stored stud.

How we read and display the object & its containts

Here's a good example of writing a Blob. It's easy to infer what the opposite would be.
