Arrays are fixed in size and can store multiple data types, while lists are dynamic and can only store one data type.

• Arrays are declared with a fixed size, while lists can grow or shrink dynamically.

• Arrays can store multiple data types, while lists can only store one data type.

• Arrays are accessed using an index, while lists are accessed using an iterator.

• Example: int[] arr = new int[5]; List list = new ArrayList<>();

OOPs concepts are fundamental to software engineering. They include inheritance, polymorphism, encapsulation, and abstraction.

• Inheritance allows a class to inherit properties and methods from a parent class.

• Polymorphism allows objects to take on multiple forms and behave differently based on the context.

• Encapsulation is the practice of hiding implementation details and exposing only necessary information.

• Abstraction is the process of identifying essential features of an objec...read more

• MySQL is a specific relational database management system that uses SQL.

• MySQL is open source and free to use, while other SQL-based systems may require licensing fees.

• MySQL has its own unique syntax and features, such as the ability to handle large amounts of data and support for multipl...read more

Compiler translates entire code into machine code while interpreter translates line by line.

• Compiler converts source code into executable code while interpreter executes code directly.

• Compiler generates error messages after the entire code is compiled while interpreter generates error messages line by line.

• Compiler produces faster and efficient code while interpreter produces slower code.

• Examples of compilers are GCC, Clang, and Visual C++ while examples of interpreters are P...read more

Overloading is having multiple methods with the same name but different parameters. Overriding is having a method in a subclass with the same name and parameters as in the superclass.

• Overloading is used to provide different ways of calling the same method with different parameters.

• Overriding is used to provide a specific implementation of a method in a subclass that is already defined in the superclass.

• Overloading is resolved at compile-time based on the number and types of a...read more

OOPs provides modularity, reusability, and extensibility in software development.

• OOPs allows for encapsulation of data and behavior, leading to more secure and maintainable code.

• Inheritance and polymorphism enable code reuse and reduce redundancy.

• Abstraction allows for the creation of simpler and more intuitive interfaces for complex systems.

• OOPs promotes modular design, making it easier to modify and extend code.

• Examples of OOPs languages include Java, Python, and C++.

DBMS is a software to manage databases while RDBMS is a type of DBMS that uses a relational model.

• DBMS stands for Database Management System while RDBMS stands for Relational Database Management System.

• DBMS can manage any type of database while RDBMS uses a relational model to manage data.

• RDBMS ensures data integrity and consistency through the use of constraints and normalization.

• Examples of DBMS include MySQL, Oracle, and Microsoft Access while examples of RDBMS include MyS...read more

Palindrome is a word or phrase that reads the same backward as forward. Reverse is the opposite order of a given sequence.

• Palindrome logic involves comparing the first and last characters of a word/phrase and moving towards the center until all characters are compared.

• Reverse logic involves swapping the first and last characters of a sequence and moving towards the center until all characters are swapped.

• Examples of palindrome words/phrases: level, radar, madam, racecar.

• Examp...read more

Prime number code is a program that identifies prime numbers.

• A prime number is a positive integer greater than 1 that has no positive integer divisors other than 1 and itself.

• The code can be written using a loop to check if a number is divisible by any number other than 1 and itself.

• One common method is the Sieve of Eratosthenes, which generates all prime numbers up to a given limit.
