Java Array Programs

An array is a data structure consisting of a collection of elements (values or variables), of the same memory size, each identified by at least one array index or key. An array is a linear data structure that stores similar elements (i.e. elements of similar data type) that are stored in contiguous memory locations. 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.

Additionally, we will discuss the basics and advanced Java Arrays programs and for each type of program, we’ve provided illustrative examples to further enhance your learning. Each program comes with a detailed description, Java code, and output. All of the examples have been thoroughly tested on both Windows and Linux systems.

Java Arrays Program – FAQs

1. What is an example of an array in real life?

Here are some examples of arrays that we see in our day-to-day life –

Student Grades: In a classroom, you can use an array to store the grades of each student in a particular subject. Each element of the array would represent the grade of a specific student.

List of Phone Contacts: Your smartphone’s contact list is essentially an array. Each entry in the list represents a contact, and you can easily search, add, or delete contacts using array-like data structures.

High Scores in a Game: Video games often use arrays to store and display high scores achieved by players. Each element of the array represents a player’s score.

2. What is array in Java with example?

An array is a group of similar elements (i.e. elements of similar datatype) that are stored in a sequence of memory locations. for example, if we wish to store the contacts on our phone, then the software will simply place all our contacts in an array.

3. What are the different types of arrays in Java?

In programming languages like Java and many others, arrays come in two primary types based on their dimensions: Single-Dimension Arrays and Multi-Dimensional Arrays.
