    Unmanaged Code Definition:

    Unmanaged code is often known as unsafe code. Because it is aimed at the processor architecture, unmanaged code is reliant on the modern computer, in C#.

    The CLR handles tasks such as stack management, memory allocation, and release, among other things, so the programmer is free to focus on other things.

    Whenever a computer uses the word “unsafe,” the system recognizes he or it will be in control of the program. However, problems like buffer overflows can occur if a coder creates faulty code.

    When the .NET framework was released, it was necessary to facilitate calling and integrating unmanaged code into C# programs. This one was applicable to any language that used the .NET framework, not even C#.

    There are two main services that provide this assistance. The first one is InteropServices, and the second is Platform Invoke Technologies.

    To ingest unmanaged code, you must match one of four factors to be identified;

    • (specify the function name and the DLL which holds it).
    • Make a class that holds and groups DLLs.
    • Prototypes should be written in managed code.
    • Make a call to a DLL function.

    Advantages Of An Unmanaged Code:

    • Unsafe code enhances the validity and reliability of the program.
    • The coder is accessible at a low level.
    • Unsafe code is used to communicate with the storage.

    Disadvantages Of Unmanaged Code:

    • There is no safety in the app.
    • Errors must be dealt with by the programmer.
    • Garbage disposal is not implemented automatically.
    • When unsafe code is used, data validation is skipped, which might result in errors.

    View Data Definition:

    We can transfer database schema from a controller to a view in numerous ways in an ASP.NET MVC application, including View Bag, View Data, Temp Data, Session, and Application, as well as highly typed views.

    You may also use the Session and Application State variables to handle data during a user session or across the project, just like we do in our standard WebForms.

    View Data is a technique in the ASP.NET MVC Architecture for passing data from a management function definition to a view.

    View Data is declared as a component with the type View Data Dictionary in the Controller Base object.

    If you correct it and choose to go to description, you’ll see that View Data is described as a property in the Controller Base class with the type View Data Dictionary.

    View State Definition:

    View state is stored in a structure and is immediately accessible when the page loads. The values stored in the view state are not transferable among pages.

    The view state is enabled by default, and independent of whether that is utilized during a component, it serializes the data in every component on the page.

    The Enable View State attribute must be set to false to deactivate the view state for a single control.

    The Enable View State Mac property is used to recognize any effort or approach to corrupt the view state.

    View state’s general characteristics include storing the values of regulated characteristics and pages discovered in the responsible page without the need of a session, preserving the value of the direct authority after a post-back procedure, and creating a custom view state supplier for storing view state information from the database.

    View state is simple to set up and requires no system resources. It also comes with better security measures, compacted or encrypted, and helps with Unicode implementations.

    The disadvantages of view state, on the other hand, are numerous. The performance is not optimal for big amounts of data, as huge values may cause the view state to be slow. Only the variables for the very same page can be saved in the view state. It also poses a security concern and necessitates additional coding to ensure data protection.

How can you understand the definition of exception handling? What does exception handling do? Is exception handling an unanticipated event? How many exceptions in Java are there?

    Definition of Exception Handling:

    An exception handler is a piece of code that specifies what a program should do when an unexpected event interrupts the normal flow of its instructions. In the context of computers, an exception is an unanticipated event that occurs during the execution of a program and disturbs the flow of its commands.

    There are two sorts of exceptions in Java:

    • Checked exceptions are ones that are examined when the code is developed; for the most part, the program is expected to rebound from them, or exception handlers are inserted into programs to specify what the program should do when certain circumstances are met.
    • Unchecked exceptions are unanticipated events that occur during the execution of a program. These can be managed in certain circumstances, but not in most. One sort of uncontrolled exception is an error. 

    Programs connect with the operating system and other software systems through multiple levels. When a checked exception occurs, the procedure that caused it creates this exception object that contains information such as the type of exception and the state of the program at the time of the occurrence.

    Throwing an exception refers to the creation and subsequent passing of this item. The method sends the object to the runtime system, which examines the exception handler code levels that satisfy the exception object’s specifications. The exception handler is said to catch an exception in this scenario.

    The operating system creates a fatal exception message if an adequate exception handler cannot be identified, which implies the program must close and maybe the computer as well.

    Method Overriding Definition:

    The state of overriding lets a subclass or child class specify a specific implementation function that is already sent by one of its super classes or parent classes in any object-oriented programming language. When a subclass’s method has a similar name, value, area, or sign, and return type(or sub-type) as a method in its superclass, the subclass’s method is said to override the super-method class’s.

    One way that Java gets Runtime Polymorphism is by method overriding. However, the child class’s version is used when a method is applied using an object from a subclass. In other words, the version of an overridden method that gets performed is determined by the type of the object being referenced to, not the type of the reference variable.

    Overriding method rules are as given below:

    • Overriding: An overriding method’s access modifier can grant more, but not less, access than the overridden method. A protected instance method in the superclass, for example, can be made public in the subclass but not private. This will cause a compile-time error.
    • Final methods cannot be overridden: We declare a method as final if we do not want it to be overridden.
    • Private methods: These methods cannot be overridden since they are bonded at build time. We can’t even override secret methods in a subclass as a result.
    • The return type (or subtype) of the overriding method must match: Since Java 5.0, The return type of a child class’s overriding method can be many, but it must be a subtype of the parent’s return type. Covariant return type describes this phenomenon.
    • Invoking an overridden method from a subclass: The super keyword can be used to apply the parent class method in an overriding practice.

    To avoid a compile-time error, derived concrete classes must override abstract methods in an interface or abstract class.

    Overriding and synchronized/strictfp methods: 

    The availability of a synchronized/strictfp modifier with a technique has no influence on the overriding rules, which means a synchronized/strictfp technique can override a non-synchronized/strictfp method and vice versa.

    Overridden methods enable Java to provide polymorphism at runtime, as previously indicated. Polymorphism is important in object-oriented programming because it allows a generic class to declare methods that will be shared by all of its descendants while allowing subclasses to define the specific implementation of any or all of those methods. Java states the “one interface, various methods” element of polymorphism in various ways.

    Methodology Dynamic Object-oriented design’s dispatch mechanism is one of the most powerful code reuse and robustness techniques. The method to use existing code libraries to call methods on new class instances without recompiling while keeping a clean abstract interface is a tremendously valuable feature.
