DATA STRUCTURE: Concept and Usage of Arrays in Java

Java provides a data structure, the array, which stores a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type. Array in Java is index-based, the first element of the array is stored at the 0th index, the 2nd element is stored on the 1st index, and so on.
