Learn how to use arrays in Java to store and process fixed-size collections of elements of the same type. Find out how to declare, create, access, sort, search, and reverse arrays, and how to use the Arrays class methods. 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. Learn about Arrays, the most common data structure in Java. Understand how to write code using examples and practice problems. Java Arrays allow you to store multiple values of the same type in a single variable. It is important to understand them for efficient coding whether you are building a simple or complex application. I have created this guide to help you explore the Java Arrays basics. This includes how to declare, initialize and access them. Let’s get into it.
