Ques:- How can multiple submits due to refresh button clicks be prevented?
Asked In :-
Infiflex Technologies, Mallow Technologies,
Right Answer:
To prevent multiple submits due to refresh button clicks in JSP, you can implement the Post/Redirect/Get (PRG) pattern. After processing the form submission, redirect the user to a different page or the same page using a `response.sendRedirect()` method. This way, refreshing the page will not resubmit the form data.

Ques:- Explain the Encapsulation principle.
Comments
Encapsulation is defined as the wrapping up of data under a single unit. It is the mechanism that binds together code and the data it manipulates.Other way to think about encapsulation is, it is a protective shield that prevents the data from being accessed by the code outside this shield.
<ul>
<li> Technically in encapsulation, the variables or data of a class is hidden from any other class and can be accessed only through any member function of own class in which they are declared.</li>
<li> As in encapsulation, the data in a class is hidden from other classes using the data hiding concept which is achieved by making the members or methods of class as private and the class is exposed to the end user or the world without providing any details behind implementation using the abstraction concept, so it is also known as combination of data-hiding and abstraction..</li>
<li> Encapsulation can be achieved by: Declaring all the variables in the class as private and writing public methods in the class to set and get the values of variables.</li>
</ul>

Ques:- How do you handle offline functionality in a mobile app
Asked In :-
Toxsl Technologies, TRICON INFOTECH PVT, SPARX IT SOLUTIONS, RAKUTEN INDIA ENTERPRISE PVT, infobell IT solutions, Grapelime Infotech, 9series Solutions, Sarvaha Systems, Aruba Networks, Uolo Technology,
Right Answer:
To handle offline functionality in a mobile app, implement local data storage using options like SQLite, Realm, or SharedPreferences. Use caching strategies to store data when online and sync changes when the device reconnects. Additionally, provide user feedback for offline status and ensure critical features are accessible without an internet connection.

Asked In :-
Payoda, Ideas2IT, Gaian Solutions India, Infosenseglobal, GTL Software, Quick Release, Zysk Technologies, Anova Data, Aosta Software Technologies, Aggregate Intelligence,
Comments
_init__ () is a first method defined in a class. when an instance of a class is created, python calls __init__() to initialize the attribute of the object.
Following example demonstrate further:
class Employee:
def __init__(self, name, empCode,pay):
self.name=name
self.empCode=empCode
self.pay=pay
e1 = Employee("Sarah",99,30000.00)
e2 = Employee("Asrar",100,60000.00)
print("Employee Details:")
print(" Name:",e1.name,"Code:", e1.empCode,"Pay:", e1.pay)
print(" Name:",e2.name,"Code:", e2.empCode,"Pay:", e2.pay)
---------------------------------------------------------------
Output
Employee Details:
(' Name:', 'Sarah', 'Code:', 99, 'Pay:', 30000.0)
(' Name:', 'Asrar', 'Code:', 100, 'Pay:', 60000.0)

Ques:- Explain different ways to trigger / raise exceptions in your python script ?
Asked In :-
Fluid AI, Surya Software, Intelizign, RELX Group, GyanMatrix Technologies, Interview Mocha, Lexicon Networks, Onebill software, Kriti, Volksoft Technologies,
Right Answer:
In Python, you can trigger or raise exceptions using the following methods:
1. **Using the `raise` statement**: You can raise a specific exception by using `raise ExceptionType("Error message")`.
2. **Raising a built-in exception**: You can raise built-in exceptions like `ValueError`, `TypeError`, etc., directly with `raise ValueError("Invalid value")`.
3. **Using `raise` without arguments**: This re-raises the last exception caught in an `except` block.
4. **Custom exceptions**: You can define your own exception class and raise it using `raise MyCustomException("Error message")`.
5. **Using `assert` statement**: This raises an `AssertionError` if the condition is false, e.g., `assert condition, "Error message"`.
6. **Using `sys.exit()`**: This raises a `SystemExit` exception to terminate the program.

Ques:- What is MVT and MVC, and how is it related to Django?
Asked In :-
Trigent Software, Infiniti Software Solutions, AppSquadz, Addverb Technologies, EvolveWare, Paktolus, Perceptive Analytics, Gibots, Vofox Solutions, WDS,
Right Answer:
MVT stands for Model-View-Template, and MVC stands for Model-View-Controller. In Django, MVT is a variation of MVC where:
– Model: Represents the data and business logic.
– View: Handles the logic and interacts with the model to retrieve data.
– Template: Manages the presentation layer, rendering the data to the user.
Django uses MVT to separate concerns, similar to how MVC organizes code, but with a focus on templates for rendering HTML.
