Jan 11, 2024 · Below are some examples to demonstrate the use of Nested Loops: Example 1: Below program uses a nested for loop to print a 2D matrix. Example 2: Below program uses a nested for loop to print all prime factors of a number.

If a loop exists inside the body of another loop, it's called a nested loop in Java. In this tutorial, we will learn about the Java nested loop with the help of examples.

Nested Loops. It is also possible to place a loop inside another loop. This is called a nested loop. The "inner loop" will be executed one time for each iteration of the "outer loop":

Understand nested loops in Java in this step-by-step tutorial. Learn nested for, while, and do-while loops with practical examples. Get Started Now!

A nested for loop is a loop inside another loop. The inner loop executes completely every time the outer loop runs one iteration. This is particularly useful for iterating over rows and columns in two-dimensional data structures, or for printing patterns that require multiple levels of iteration.

Jan 25, 2022 · If a loop is written inside the body of the another loop, it is referred as a nested loops. There are three different types of loops supported in Java. They are for loop, while loop and do while loop.

Java allows the nesting of loops, when we put a loop within another loop then we call it a nested loop. Nested loops are very useful when we need to iterate through a matrix array and when we need to do any pattern-based questions.

Apr 2, 2025 · Nested loops consist of an outer loop and one or more inner loops. The inner loop completes all its iterations for each single iteration of the outer loop. Example: Simple Nested Loop for (int i = 1; i <= 3; i++) { for (int j = 1; j <= 2; j++) { System.out.println("Outer: " + i + ", Inner: " + j); } } Output:

Jan 28, 2025 · Nested loops are powerful constructs in Java that enable developers to tackle complex programming challenges with ease. By understanding their structure, applications, and best practices, you can harness their full potential to …

Use nested loops whenever actually needed, as nesting increases the complexity. Apply the conditions in nested loops properly, sometime incorrect conditions results as infinite loops. Nested loops are helpful when printing some pattern in multi-dimension.
