OOP (Object-Oriented Programming) is a programming paradigm based on objects and classes, promoting code reusability and modularity.
Encapsulation: Bundling data and methods that operate on the data within one unit (e.g., a class).
Inheritance: Mechanism to create a new class from an existing class, inheriting attributes and methods (e.g., a 'Dog' class inheriting from an 'Animal' class).
Polymorphism: Ability to pre...
Fail-fast iterators throw ConcurrentModificationException if the collection is modified while iterating. Fail-safe iterators do not throw exceptions.
Fail-fast iterators fail immediately if the collection is modified during iteration.
Fail-safe iterators do not throw exceptions if the collection is modified during iteration.
Fail-fast iterators are used in Java collections like ArrayList, HashMap.

Breaking down a monolith into microservices involves identifying bounded contexts, decoupling components, and implementing communication mechanisms.
Identify bounded contexts within the monolith to define the boundaries of microservices.
Decouple components by extracting them into separate services with well-defined interfaces.

Zookeeper in Kafka is a distributed coordination service used for managing and maintaining configuration information, naming, providing distributed synchronization, and group services.
Zookeeper is used by Kafka to manage broker metadata, topic configurations, and consumer group coordination.
It helps in leader election, maintaining cluster membership, and detecting failures.

Using Java Streams to filter and process a list of integers.
Use Stream.of() to create a stream from an array: Stream.of(array).
Filter elements using .filter(condition): stream.filter(x -> x > 10).
Map elements to a new form with .map(): stream.map(x -> x * 2).
Collect results into a list with .collect(Collectors.toList()): stream.collect(Collectors.toList()).
Debouncing is a technique used to limit the number of times a function is called in response to a rapid series of events.
Debouncing is commonly used in user interface interactions to prevent multiple actions from being triggered by a single event.
It involves setting a delay before executing a function, and if another event occurs within that delay, the timer is reset.
Example: Debouncing can be used in a search bar...
This code demonstrates a simple JavaScript function that adds two numbers and returns the result.
Define a function using the 'function' keyword: function add(a, b) { return a + b; }
Call the function with arguments: let sum = add(5, 10);
Use console.log to display the result: console.log(sum);
Functions can also be assigned to variables: const add = function(a, b) { return a + b; };
