Functions
In Java, functions (or methods) are blocks of code designed to perform specific tasks. They enhance code reusability, modularity, and readability. A function is defined using the public static return_type function_name(parameters) syntax.  
Return type: Specifies the data type of the value returned by the function.  
Parameters: Input values passed to the function.
Function body: Contains the code to be executed.
Recursive Functions
A recursive function is a function that calls itself directly or indirectly. They are often used to solve problems that can be broken down into smaller, similar subproblems. A base case is essential to prevent infinite recursion. For example, calculating factorial using recursion.  
Arrays
Arrays are used to store multiple values of the same data type in a contiguous memory location. They are accessed using an index starting from 0. Basic operations on arrays include:  
Declaration: Creating an array with a specified size.
Initialization: Assigning values to array elements.
Accessing elements: Retrieving values from specific indices.  
Iterating: Processing each element using loops.
Searching: Finding specific elements within the array.
Sorting: Arranging elements in a specific order.
