In this tutorial, we will learn to work with Java arrays. We will learn to declare, initialize, and access array elements with the help of examples. An array is a collection of similar data types.

Mar 28, 2025 · Example: This example demonstrates how to initialize an array and traverse it using a for loop to print each element. There are some basic operations we can start with as mentioned below: 1. Array Declaration. To declare an array in Java, use the following syntax: type [] arrayName; type: The data type of the array elements (e.g., int, String).

Jun 22, 2024 · This article provides a variety of programs on arrays, including examples of operations such as sorting, merging, insertion, and deletion of elements in a single-dimensional array.

Pre-requisite to solve these array programs in Java:- Array in Java, Multidimensional Array, Anonymous Array, Array of Objects, Jagged Array. Single-dimensional (1D) Array Programs in Java. More Simple Single Dimensional Array Programs in Java. Multi-dimensional array and Matrix Programs in Java.

Arrays are used to store multiple values in a single variable, instead of declaring separate variables for each value. To declare an array, define the variable type with square brackets:

Feb 10, 2018 · Now, let's see some examples of using an array in Java. This is the most comprehensive list of how to use an array in Java and covers everything from initializing an array to retrieving elements from an array.

Learn about Arrays, the most common data structure in Java. Understand how to write code using examples and practice problems.

To demonstrate a practical example of using arrays, let's create a program that calculates the average of different ages: sum += age; } // Calculate the average by dividing the sum by the length . And in this example, we create a program that finds the lowest age among different ages:

Here is the listing of Java programming examples on Arrays: 1. Java Programs on Largest & Smallest Numbers in an Array. 2. Java Programs on Inserting & Deleting Elements from an Array. 3. Java Programs to Perform Operations on Arrays. 4. Java Programs on Printing the Elements of an Array. 5. Single Dimensional Array Programs in Java. 6.

Arrays are a fundamental data structure in Java, providing a way to store and manipulate multiple values of the same type efficiently. Understanding how to declare, initialize, access, and perform operations on arrays is crucial for effective Java programming.
