List is mutable, tuple is immutable in Python.
Lists are mutable, meaning their elements can be changed after creation.
Tuples are immutable, meaning their elements cannot be changed after creation.
Lists are defined using square brackets [], tuples using parentheses ().
Lists are typically used for collections of similar items, tuples for fixed collections of dissimilar items.
Generators in Python are functions that allow you to iterate over a sequence of items without storing them all in memory at once.
Generators are created using a function with 'yield' instead of 'return'.
They are used to generate a sequence of values lazily, one at a time.
Generators are memory efficient as they do not store all values in memory at once.
Example: def my_generator(): for i in range(5): yield i
Example: ...

OOPS is a programming paradigm based on objects that have properties and methods.
Encapsulation: bundling of data and methods that operate on that data within a single unit
Inheritance: ability of a class to inherit properties and methods from a parent class
Polymorphism: ability of objects to take on many forms or have multiple behaviors
Abstraction: hiding of complex implementation details and showing only the necessary ...
Explanation of Super, Throw, Final and Finally
Super: used to call a method from a parent class
Throw: used to throw an exception
Final: used to declare a constant or to prevent method overriding
Finally: used to execute code after try-catch block, regardless of exception

The 4 principles of OOP are Inheritance, Encapsulation, Abstraction, and Polymorphism.
Inheritance allows a class to inherit properties and behavior from another class.
Encapsulation restricts access to certain components within a class, protecting the data.
Abstraction hides complex implementation details and only shows the necessary features.
Polymorphism allows objects to be treated as instances of their parent class.
String buffer is synchronized and thread-safe, while string builder is not synchronized and faster.
String buffer is synchronized, making it thread-safe for use in multi-threaded environments.
String builder is not synchronized, providing better performance in single-threaded applications.
String builder is faster than string buffer due to lack of synchronization overhead.
Example: StringBuffer sb = new StringBuffer(); Str
Strings are immutable in order to ensure data integrity and security.
Immutable strings prevent accidental data modification, ensuring data integrity.
Immutable strings enhance security by preventing unauthorized access or tampering.
Immutable strings allow for more efficient memory management and optimization.
Example: 'Hello' cannot be changed to 'Hella' directly, a new string must be created.
There are two types of exceptions in Java: checked exceptions and unchecked exceptions.
Checked exceptions are checked at compile time and must be handled using try-catch or throws keyword.
Unchecked exceptions are not checked at compile time and include RuntimeException and its subclasses.
Examples of checked exceptions include IOException, SQLException, and ClassNotFoundException.
Examples of unchecked exceptions include...
Linear search is a simple searching algorithm that sequentially checks each element in a list until a match is found.
Iterate through each element in the list
Compare the current element with the target value
Return the index if a match is found, otherwise return -1
JDK includes JRE and development tools, while JRE includes only the Java Runtime Environment.
JDK stands for Java Development Kit, which includes JRE and development tools like compilers and debuggers.
JRE stands for Java Runtime Environment, which includes JVM and libraries necessary to run Java applications.
JVM stands for Java Virtual Machine, which is responsible for executing Java bytecode.
