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":

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.

This tutorial covers various aspects of nested for loops in Java, including: The concept and structure of nested for loops. Syntax of a nested for loop. Example programs with detailed explanations and outputs. Best practices and tips for using nested loops effectively.

How nester loops are working. Well this is quite simple, a for loop is define as follow : Here, with one loop, // code . This will be the same as. // code. i++; If you have nested loops, the idea is the same, the inner loop will need to execute as many time as the condition is true before the outer one can increment and check his condition again.

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.

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:

May 4, 2023 · When there is one or more for loops inside a for loop, we call it a nested for loop in Java. Since one for loop is inside another for loop just like a nest, we call it a nested for loop in Java. Refer to the diagram below to understand and visualize the nested for loop in Java.

Nested for loop in Java means one for loop is present inside another for loop. It is similar to the nested-if statement where one if statement is present inside another if statement. In the case of nested for loop, the internal loop is called Inner loop, and the external loop is called outer loop.

Nested for loop in java can be used to print multiplication table. We will show one application of it. Reader can apply the logic to solve various other problems. public static void main (String[] args) { System.out. println ("Printing multiplication table start");
