Java is a popular programming language known for its platform independence and object-oriented approach.
Java is platform-independent, meaning it can run on any device with a Java Virtual Machine (JVM)
It is object-oriented, allowing for modular and reusable code
Java is widely used for developing web applications, mobile apps, and enterprise software
Popular Java frameworks include Spring, Hibernate, and Apache Struts
Encapsulation is the concept of bundling data and methods that operate on the data into a single unit, known as a class.
Encapsulation helps in hiding the internal state of an object and restricting access to it.
It allows for better control over the data by preventing direct access from outside the class.
Encapsulation also helps in achieving data abstraction, where the internal details of an object are hidden and only n...
Method overloading is having multiple methods in the same class with the same name but different parameters. Method overriding is having a method in a subclass with the same name and parameters as a method in its superclass.
Method overloading is achieved by having methods with the same name but different parameters in the same class.
Method overriding is when a subclass provides a specific implementation of a method tha...
Exception handling is the process of responding to the occurrence of exceptions during program execution.
Exception handling allows developers to gracefully handle errors and prevent program crashes.
It involves using try, catch, and finally blocks to handle exceptions.
Examples of exceptions include NullPointerException, ArrayIndexOutOfBoundsException, and IOException.
Remove duplicate elements in string using recursion
Create a recursive function that takes a string and a set to keep track of unique characters
Check if the current character is already in the set, if so skip it
Append the current character to the result and add it to the set
Recursively call the function with the remaining substring

To create a pipeline in Databricks, you can use Databricks Jobs or Apache Airflow for orchestration.
Use Databricks Jobs to create a pipeline by scheduling notebooks or Spark jobs.
Utilize Apache Airflow for more complex pipeline orchestration with dependencies and monitoring.
Leverage Databricks Delta for managing data pipelines with ACID transactions and versioning.
An abstract class is a class that cannot be instantiated and may contain abstract methods that must be implemented by its subclasses.
Cannot be instantiated directly
May contain abstract methods
Used as a blueprint for other classes
Abstraction is the process of hiding complex details and showing only the essential features of an object or system.
Abstraction allows us to focus on what an object does, rather than how it does it
It helps in simplifying complex systems by breaking them down into smaller, more manageable parts
Examples of abstraction include using a car without needing to understand its internal combustion engine, or using a smartphone
QuickSort is one of the best sorting algorithms with an average time complexity of O(n log n).
QuickSort is a divide and conquer algorithm that works by selecting a 'pivot' element and partitioning the array around the pivot.
It has an average time complexity of O(n log n) and a worst-case time complexity of O(n^2).
Example: ['apple', 'banana', 'cherry', 'date', 'fig'] can be sorted using QuickSort.
Example: ['3', '1', '4'...
Bubble sorting has a time complexity of O(n^2) for a sorted list.
Bubble sorting has a worst-case time complexity of O(n^2) for a sorted list.
The time complexity does not change even if the list is already sorted.
Example: If we have a sorted list of size n, bubble sorting will still take O(n^2) time.
