Java Programming - Lesson 5
Java Arrays Explained: Declaration, Initialisation, Indexing, Length and Multidimensional Arrays Introduction One of the fundamental concepts every aspiring Java programmer must understand is the use of arrays. Imagine developing a programme that needs to store the examination scores of 100 students. Creating 100 separate variables would be inconvenient, difficult to manage and unnecessarily complicated. Fortunately, Java provides a more organised approach through arrays. An array allows you to store multiple values of the same data type under a single variable name. Rather than declaring numerous individual variables, you can create one array and access its contents whenever necessary. In this tutorial, you will learn how to declare, initialise and access arrays in Java. You will also discover how to determine their lengths, process their elements using loops, create larger arrays and work with multidimensional structures. Let's get started! 1. What Is an Array in Java? An array i...
