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.

First row contains 4 elements, second row contains 2 elements and third row contains 3 elements. package com.w3schools; import [Link]; public class Test { public static void main(String args[]){ int[][] jaggedArray = new int[3][]; jaggedArray[0] = new int[]{0,1,2,3}; jaggedArray[1] = new int[]{4,5}; jaggedArray[2] = new int[]{6,7,8};...

January 22, 2024 - We use nested loops to iterate over the jagged array and calculate the sum of each row. The outer loop iterates over the rows, and the inner loop iterates over the columns of each row.

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]

February 10, 2026 - In Java, we can create a dynamic jagged array by creating an array of arrays, where each sub-array represents a row in the two-dimensional array. After thar, we can allocate memory to each sub-array to specify its number of columns. The following example shows the working of dynamic jagged ...

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.

February 11, 2022 - Indexing of Java starts from 0 and goes up to the length of the array minus 1 (0 to length-1). Arrays are stored in the heap memory. ... In order to declare a jagged array, we need to write its name preceded by its data type. The new keyword is used to create the object.

In Java, this is done using the new keyword. Unlike a matrix array, each row in a jagged array can have a different number of columns.

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:

February 21, 2025 - String[][] classStudents = new String[3][]; → Creates a jagged array with 3 rows (classes).

A jagged array is an array of arrays such that the member arrays can be of different sizes.

September 17, 2025 - A jagged array allows rows of unequal size. This makes it flexible for many real-world problems. ... They save memory because rows can be shorter. They handle data that is not rectangular. They give flexibility in storing irregular data. They are easy to manage and access. The syntax is simple. You declare an array of arrays.
