January 22, 2024 - We then use nested loops to iterate over the jagged array and print the names of students in each grade. The outer loop iterates over the rows (grades), and the inner loop iterates over each grade’s columns (students). ... public class JaggedArrayExample { public static void main(String[] args) { // Declare and initialize a 2D jagged array to store names of students in different grades String[][] jaggedArray = { { "Ram", "Laxman" }, // Grade 1 students { "Rahul", "Gauri", "Komal" }, // Grade 2 students { "Ajinkya", "Virat", "Tejaswi", "Sanju" } // Grade 3 students }; // Accessing and printin

April 1, 2025 - We have already discussed Multi-dimensional arrays in Java in one of our previous tutorials. In this tutorial, we will discuss what is a Jagged Array and how to use it in your program. This array is also known as “Ragged array” and is basically an array of arrays. ... It is an array of arrays where each element is, in turn, an array. A special feature of this type of array is that it is a Multidimensional array whose each element can have different sizes. For Example, a two-dimensional array in Java is an array of single dimension array.

February 8, 2025 - A jagged array in Java is an array where each row can have a different number of columns. It’s not too hard once you understand it, but it can confuse you if you’ve never seen it before. Let’s go through it with an example.

April 9, 2025 - Let's get our hands dirty with some jagged array Java examples.

February 10, 2026 - For example, a jagged array with three rows can have the first row with three elements, the second with two elements, and the third with four elements.

June 23, 2020 - Jagged array is a multidimensional array where member arrays are of different size. For example, we can create a 2D array where first array is of 3 elements, and is of 4 elements. Following is the example demonstrating the concept of jagged array.

To work with jagged arrays in Java, we need to follow these steps: Declare an array - Define the reference of the array with a specific data type. Create an array - Allocate memory for the array using the new keyword. Initialize an array - Assign values to the elements of the array. Retrieve elements of an array - Access array elements using their row and column index. We will go through each step with examples below.

February 11, 2022 - Consider an example of a 2-D array with 2 rows, here each row can have a different number of columns, i.e, elements. They don't need to be equal in length. It is important to understand that 2-D arrays have the same number of columns in each row. Whereas in jagged arrays, the rows have different ...

March 29, 2021 - Jagged array is (using for-each loop): 10 9 8 7 5 6 88 30 15 50 10 20 30 40 50 Jagged array is (using for loop): 10 9 8 7 5 6 88 30 15 50 10 20 30 40 50 · In this program, we used length property to find the size of each parent and child array.

June 9, 2026 - This example demonstrates how to create a jagged array with sizes determined at runtime. Problem Statement: Create a program that allows users to define the dimensions of a jagged array dynamically and populate it with their input. import java.util.Scanner; public class DynamicJaggedArray { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); // Get number of rows from user System.out.print("Enter the number of rows for jagged array: "); int numRows = scanner.nextInt(); // Create jagged array with the specified number of rows int[][] jaggedArray = new int[numRows]

December 30, 2024 - A jagged array in Java is an array of arrays with varying row sizes, making it non-rectangular. Each row can have a different number of elements.

Then, you can initialize each element of the outer array with a new array of the desired size. For example, the following code creates a jagged array with three rows, where the first row has three elements, the second row has two elements, and the third row has four elements:

December 3, 2024 - ... // Java program to demonstrate ... static void main(String[] args) { int r = 5; // Declaring 2-D array with 5 rows int arr[][] = new int[r][]; // Creating a 2D array such that first row // has 1 element, second row has two // ...

Java program to reverse a given string with preserving the position of spaces

July 7, 2026 - The elements of a jagged array can be of different dimensions and sizes, unlike C-styled arrays that are always rectangular. We know that a two-dimensional array is nothing but an array of single-dimensional arrays. Therefore, it is possible to create a two-dimensional array in Java, where individual one-dimensional arrays have different lengths. To illustrate, consider the following example, which declares a single-dimensional array having three elements, each of which is a single-dimensional integer array.

// Another Java program to demonstrate 2-D jagged // array such that first row has 1 element, second // row has two elements and so on. class Main { public static void main(String[] args) { int r = 5; // Declaring 2-D array with 5 rows int arr[][] = new int[r][]; // Creating a 2D array such ...

public class jagged_Array_for { public static void main(String args[]) { //Jagged Array using En hanced For Loop in Java Programming int a[][]={ {10,20,30,40}, {10,20,30}, {10,20,30,50} }; for(int k[]:a) { for(int l:k) { System.out.print(" "+l); } System.out.println(""); } } }

March 8, 2026 - For example, you might use a jagged array to store the words in each sentence of a paragraph, where each sentence has a different number of words. Here's how you declare and initialize a jagged array in Java: data_type[][] array_name = new ...
