7. Nested for Loops

Nested loops in programming allow for loops to be placed inside other loops, enabling complex iteration structures. Java supports nesting for all loop types, with the nested 'for' loops being the most common. Clarity and efficiency in code can be compromised by excessive nesting, thus proper usage and indentation are crucial.

What we have learnt

Nested loops are loops that run within another loop, commonly found in Java using 'for' loops.
The outer loop runs, and for each iteration, the inner loop runs completely before continuing with the outer loop.
Proper indentation and cautious use of variables help maintain the efficiency and readability of nested loop structures.

Key Concepts

Term: Nested Loop

Definition: A nested loop is a loop inside another loop, allowing for complex iterations and control flow in programming.
Term: Outer Loop

Definition: The loop that encompasses the inner loop in nested looping structures; it dictates the primary iterations.
Term: Inner Loop

Definition: The loop that runs within the outer loop; it executes completely for each iteration of the outer loop.
Term: Syntax of Nested for Loops

Definition: The structured format that dictates how nested loops are written, including initialization, condition, and update statements.
Term: Complexity

Definition: Refers to how nested loops can complicate code structure and efficiency if not used judiciously.
