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. In Java, an array is an important linear data structure that allows us to store multiple values of the same type. Arrays in Java are objects, like all other objects in Java, arrays implicitly inherit from the java.lang.Object class. 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. For your convenience, Java SE provides several methods for performing array manipulations (common tasks, such as copying, sorting and searching arrays) in the java.util.Arrays class.
