What is Difference between abstract class and interface? tccicomputercoaching.com

Definition:

An abstract class is a class that is declared abstract – it may or may not contain abstract
methods. The keyword “abstract” is used to create an abstract class just before the class keyword in the class declaration.

In simple terms, an interface is a collection of abstract methods that is used to specify a behaviour that the class has to implement.

Difference between Abstract Class and Interface in Java

Implementation

• Implementation for Java abstract class cannot be provided by interface but an abstract class can provide an implementation for the interface in Java.
• “Method Type” of Abstract Class and Interface in Java – The second major difference between the two is that while an interface can only have abstract methods, an abstract class can have both abstract and non-abstract methods. However, since Java 8, an interface can have default and static methods too.
• “Access Modifiers” of Abstract Class and Interface in Java – An abstract class can have public, private and protected access modifiers, however methods of an interface are implicitly public and abstract. You cannot use any other access modifier with interface methods’.

Inheritance vs. Abstraction

• An abstract class can be extended using the keyword ‘extends’ while a Java interface uses the keyword ‘implements’ to be implemented.
• “Keyword” of Abstract Class and Interface in Java– While “abstract” keyword is used to declare an abstract class method as abstract, however, interfaces are entirely a different story; they can only have public, static final constants and method declarations.
• “Use” of Abstract Class and Interface in Java – While an interface is ideal for type declaration, an abstract class is best suited for code reusability and evolution perspective. An interface looks like a class, but it is not a class.
• “Reliability” of Abstract Class and Interface in Java– Another major difference between an abstract class and an interface is that the former is a bit faster than the latter because a search is usually involved in an interface before any overridden method is called in Java.

Final Java Variables

• Abstract class in Java may or may not have variables declared as final but in Java interfaces, it is by default that they will declare final.

Type of Variable

• Java interface can only have static and final variables while abstract class in Java can have both final and non-final as well as static and non-static variables.

How Does Python Handle Memory Management? tccicomputercoaching.com

Python uses private heaps to maintain its memory. So the heap holds all the Python objects and the data structures. This area is only accessible to the Python interpreter; programmers can’t use it.

And it’s the Python memory manager that handles the Private heap. It does the required allocation of the memory for Python objects.

 

Python employs a built-in garbage collector, which salvages all the unused memory and offloads it to the heap space.

Python is most popular Language in present time.

TCCI teach python from scratch to Advance level to the interested people.

What is SQL? What is an Importance of SQL? tccicomputercoaching.com

What is SQL ?

SQL stands for Structured Query Language. SQL is a language for interacting with data in a database. SQL works following:

Create, Putting data into tables. Read Query data out of a table. Update Change data already in a table .Delete Remove data from the table.

What is an Importance of SQL?

SQL helps a user program to update the computer database by removing old data, modifying hitherto stored data, and adding new data.

It works by understanding and analyzing databases that include data fields in their tables. For example, we can take a large organization where a lot of data have to be stored and managed.

SQL DDL provides commands for defining relation schemas, deleting relations, modifying relation schemas. SQL includes commands for beginning and ending the transactions.

What is the difference between NULL and Void Pointer? tccicomputercoaching.com

A null pointer is basically a null value assigned to a pointer of any data type whereas a void pointer is a data type which remains void as long as an address of a data type is not assigned to it.

The data type of the pointer is nothing but the type of data stored at the memory location where the pointer is pointed. When you are not sure about the type of data that is going to store at a particular memory location, you need to create the void pointer.

Null pointer does not contain a reference of any variable/value. Hence we may state that it has a NULL as its value making it a null pointer.

void pointer is always of type void *

Mainly such pointers are used for dynamic memory allocations (using malloc(), calloc() and realloc() functions) , where memory block reserved is pointer to by a void pointer and as the pointer value is returned it has to be explicitly type casted to a particular desired type.

Student of IT Field can update their Programming knowledge at TCCI.
