Java Bean
➡️ It is a reusable software component.
➡️ A bean encapsulates many objects into one object, so we can access this object from multiple places.
➡️ It provides the easy maintenance.

Java Bean is a java class that should follow following rules:
➡️ It should have a no-argument or zero argument Constructor.
➡️ It should be Serializable.
➡️ It should provide methods to set and get the values of the properties (getter & setter methods).

Java Bean Property types
➡️ Simple : It has a single value whose changes are independent of changes in any other property.
➡️ Indexed : Such bean supports a range of values instead of a single value.
➡️ Bound : A change to the property results in a notification being sent to some other bean.
➡️ Constrained : Here a change to the property results in validation by another bean in this property. The other bean may reject the change if it is not appropriate.

  5. Avoid Spyware/Adware
  6. Protect Passwords
  7. Back up Important Files

Cyber Safety Tips 👇
✅ હંમેશા લેટેસ્ટ સોફ્ટવેર ઉપડૅટ ઇન્સટોલ કરવા
✅ એન્ટી વાયરસ સોફ્ટવેર નો ઉપયોગ કરવો
✅ ફાયરવોલ સોફ્ટવેર નો ઉપયોગ કરવો
✅ કોઈ સોફ્ટવેર કે જેમ વારંવાર એડ આવતી હોય તો તેનો ઉપયોગ ન કરવો

❌ તમારા આઈ.ડી. અને પાસવૉર્ડ કોઈ સાથે શેર ન કરવા

Watch “JSP Part-19 | JSP JDBC with CRUD – Code Optimization, Retrieving Data using Array List (Gujarati)” on YouTube

by

➡️ Retrieving data using Array List (array list of objects)
➡️ Code Optimization

Here, Array List us used to hold the list of object of type EmpBean.

JSP with Bean and Data access object (DAO). JSP is the normal jsp page which uses the bean to store employee information. The DAO file also know an Data Access Layer of our application, contains the code perform database operations such as add, change, delete etc.,

This video demonstrates the best usage of MVC (Model View & Controller) architecture in Java.
➡️ The model here is the EmpBean which holds the employee information.
➡️ The index page is the View which is interface used by client to enter the input and get to view the output.
➡️ The controller here the file which accepts the request from client and sets to bean and bean finally manages the database operation.

CRUD – Create, Read, Update & Delete

With reference to previous video 👉 https://youtu.be/63cIEAnz7Hc which consist of Add operation & Display operation.
and 👉 https://youtu.be/Asi4H3QCHY4 which consist of Delete operation.

In this video the same example has been extended to support Edit/Update operation using display page. The link (url to edit page and ID of record to be updated) has been generated in the display page for to update record.

Once user click the Edit link , the control is transfer to edit.jsp page, where the the ID of the record to be updated is fetch from request object and the other details are set in text boxes so that user can edit the data.

There is a Update (submit) button which transfer user control to the update.jsp page, where all the submitted data is updated into emp table.

Model View & Controller
▶️ It is a design pattern that separates the business logic, presentation logic and data.
▶️ Model represents the state of the application i.e. data. It can also have business logic. (Data & business logic)
▶️ View represents the presentation i.e. UI (User Interface).
▶️ Controller acts as an interface between View and Model. Controller intercepts all the incoming requests. (Controller is a request handler)
