Sort array in descending order, find 2nd smallest number without using inbuilt function.

• Iterate through the array and compare each element to find the smallest number.

• Then iterate again to find the second smallest number.

• Implement a sorting algorithm like bubble sort or selection sort to sort the array in descending order.

Bubble sort repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order. Selection sort selects the smallest element from the unsorted portion and swaps it with the first unsorted element.

• Bubble sort has a time complexity of O(n^2) in worst case, while selection sort has a time complexity of O(n^2) in all cases.

• Bubble sort is stable, meaning it preserves the relative order of equal elements, while selection sort is not stable.

• Bu...read more

There are two types of constructors in Java: default constructor and parameterized constructor.

• Default constructor has no parameters and is automatically created by the compiler if no constructor is defined.

• Parameterized constructor takes parameters and is used to initialize the object with specific values.

print() prints the output without moving to the next line, while println() prints the output and moves to the next line.

• print() does not add a new line character at the end of the output

• println() adds a new line character at the end of the output

• Example: System.out.print("Hello"); // prints Hello without moving to the next line

• Example: System.out.println("World"); // prints World and moves to the next line

Pillars of OOPs are four fundamental principles - Inheritance, Encapsulation, Abstraction, and Polymorphism.

• Inheritance: Allows a class to inherit properties and behavior from another class.

• Encapsulation: Bundling data and methods that operate on the data into a single unit.

• Abstraction: Hiding the complex implementation details and showing only the necessary features.

• Polymorphism: Ability to present the same interface for different data types.

Denormalization is the process of adding redundant data to a database to improve read performance.

• Reduces the need for joins in queries

• Increases read performance at the expense of slower writes

• Commonly used in data warehousing and reporting applications

Atomicity refers to the property of a transaction in a database system that ensures all operations within the transaction are completed successfully or none at all.

• Atomicity ensures that all operations within a transaction are completed successfully or none at all

• If any operation within a transaction fails, the entire transaction is rolled back

• Example: transferring money from one account to another - either the full amount is transferred successfully or no money is transferre...read more

Recursively search for an element in an array of strings

• Create a recursive function that takes the array, target element, and current index as parameters

• Check if the current index is out of bounds or if the element at the current index matches the target

• If the element is found, return the index; otherwise, recursively call the function with the next index

Abstraction is the process of removing unnecessary details and focusing on essential characteristics.

• Abstraction involves hiding complex implementation details and exposing only relevant information.

• It helps in simplifying the problem-solving process by focusing on high-level concepts.

• For example, in programming, classes and objects are used to implement abstraction by encapsulating data and methods.

• Abstraction is a key concept in object-oriented programming.

• It allows for cre...read more
