Have to solve 2 coding questions on coding platform
Oops concept in Java refers to Object-Oriented Programming principles like inheritance, encapsulation, polymorphism, and abstraction.
Inheritance allows a class to inherit properties and behavior from another class.
Encapsulation hides the internal state of an object and restricts access to it.
Polymorphism allows objects to be treated as instances of their parent class.
Abstraction focuses on the essential characteristics
Microservices communicate through lightweight protocols like HTTP, messaging queues, and RPC.
HTTP: RESTful APIs are commonly used for communication between microservices.
Messaging queues: Services can communicate asynchronously through message brokers like RabbitMQ or Kafka.
RPC (Remote Procedure Call): Services can directly call each other's functions over the network.
The static keyword in Java is used to create class-level variables and methods that can be accessed without creating an instance of the class.
Static variables are shared among all instances of a class
Static methods can be called without creating an instance of the class
Static blocks are used to initialize static variables
DB connections flow in Spring Boot involves configuring data source, creating connection pool, and managing transactions.
Configure data source in application.properties or application.yml
Use @EnableJpaRepositories to enable JPA repositories
Create connection pool using HikariCP or Tomcat JDBC
Manage transactions using @Transactional annotation
REST is lightweight, uses standard HTTP methods, and is more flexible. SOAP is more rigid, uses XML, and has built-in security features.
REST uses standard HTTP methods like GET, POST, PUT, DELETE for communication.
SOAP uses XML for communication and has built-in security features like WS-Security.
REST is more lightweight and flexible, making it easier to work with in modern web development.
SOAP is more rigid and has a ...

JDBC steps involve loading the driver, establishing a connection, creating a statement, executing the query, and processing the results.
Load the JDBC driver using Class.forName() method
Establish a connection to the database using DriverManager.getConnection() method
Create a statement object using the connection.createStatement() method
Execute the query using statement.executeQuery() method
Process the results by iterati

Polymorphism is the ability of a function or method to behave differently based on the object it is called with.
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: Animal class with methods eat() and sleep(). Dog and Cat classes can inherit from Animal and override

The task is to determine if a given singly linked list forms a cycle or not.
A cycle occurs when a node's next points back to a previous node in the list.
To solve this problem, we can use the Floyd's Cycle-Finding Algorithm.
The algorithm uses two pointers, one moving at a normal pace and the other moving twice as fast.
If there is a cycle, the fast pointer will eventually catch up to the slow pointer.
If the fast pointer ...

The minimum depth of a binary tree is the number of nodes along the shortest path from the root node down to the nearest leaf node.
The minimum depth can be found by performing a breadth-first search (BFS) traversal of the binary tree
During the BFS traversal, keep track of the current level and increment the depth by 1 for each level
Stop the BFS traversal when a leaf node is encountered and return the depth as the minim
Given two arrays A

The problem is to find the intersection of two sorted arrays.
Use two pointers to iterate through the arrays.
Compare the elements at the current pointers and move the pointers accordingly.
If the elements are equal, add it to the intersection array and move both pointers.
If the element in the first array is smaller, move the first pointer.
If the element in the second array is smaller, move the second pointer.

A mutex is a binary semaphore used for mutual exclusion, while a semaphore is a generalized synchronization primitive.
Mutex is used to protect a critical section of code, allowing only one thread to access it at a time.
Semaphore is used to control access to a shared resource, allowing multiple threads to access it simultaneously.
Mutex has ownership, meaning the thread that locks it must unlock it.
Semaphore does not hav...
