Arrays in Java
Arrays in Java are fundamental data structures used to store elements of the same type sequentially in memory. They provide a convenient way to manage collections of data where each element is accessed by its index. Basics of Arrays An array in Java is a fixed-size container that holds a specific number of elements of the same data type. This means all elements in an array must be of the same type such as integers ( int ), floating-point numbers ( double ), characters ( char ) or objects ( Object ). Declaring and Initializing Arrays To declare an array in Java we specify the type of elements followed by square brackets [] and the array name: dataType[] arrayName; For example, to declare an integer array named numbers : int[] numbers; Arrays in Java are objects and like all objects they must be instantiated with the new keyword before they can be used: arrayName = new dataType[arraySize]; For instance, to create an integer array numbers with a si...
