A class is a blueprint or template for creating objects, while an object is an instance of a class.
A class defines the properties and methods that an object will have.
An object is created from a class using the 'new' keyword.
Multiple objects can be created from a single class.
Classes can inherit properties and methods from other classes.
Objects can have unique values for their properties, while classes define the struc
Inheritance is a mechanism in OOP where a new class is derived from an existing class.
Inheritance allows for code reuse and promotes code organization.
The derived class inherits all the properties and methods of the base class.
The derived class can also override or extend the functionality of the base class.
There are different types of inheritance such as single, multiple, and hierarchical inheritance.
Example: A Car cl...

Merge Sort is a divide and conquer algorithm that divides the input array into two halves, recursively sorts them, and then merges the sorted halves.
Divide the input array into two halves
Recursively sort the two halves
Merge the sorted halves back together
Quick Sort is a popular sorting algorithm that uses a divide-and-conquer approach to sort elements in an array.
Choose a pivot element from the array.
Partition the array into two sub-arrays: elements less than the pivot and elements greater than the pivot.
Recursively apply the same process to the sub-arrays.
Combine the sorted sub-arrays to get the final sorted array.

Static methods belong to the class itself, while default methods are part of an interface in Java.
Static methods can be called without creating an instance of the class, while default methods are used to provide a default implementation in interfaces.
Static methods are defined using the 'static' keyword, while default methods are defined using the 'default' keyword in Java.
Static methods cannot be overridden in subclas...
