- Q1. Describe polymorphism
- Ans.
Polymorphism is the ability of a single function or method to operate on different types of data.
Polymorphism allows objects of different classes to be treated as objects of a common superclass.
There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).
Example: Inheritance in object-oriented programming languages like Java allows for polymorphism.

- Q1. What is the difference between abstract class and an interface in Java?
- Ans.
Abstract class can have both abstract and non-abstract methods, while interface can only have abstract methods.
Abstract class can have constructors, member variables, and methods, while interface cannot.
A class can implement multiple interfaces but can only extend one abstract class.
Abstract classes are used to define a common behavior among subclasses, while interfaces are used to define a contract for classes to impl...
- Q2. An abstract class can have method implements and abstract method, while an interface only contains abstract method (before Java 8) . Abstract classes support single inheritance, whereas interfaces support ...
- Ans.
Abstract classes can have both implemented and abstract methods, while interfaces can only have abstract methods. Abstract classes support single inheritance, interfaces support multiple inheritance.
Abstract classes can have both implemented and abstract methods, providing more flexibility in design.
Interfaces can only have abstract methods, promoting a more strict contract for implementing classes.
Abstract classes sup...

- Q1. What is the implementation of Merge Sort in Java?
- Ans.
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
- Q2. What is the implementation of the Quick Sort algorithm in Java?
- Ans.
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...
