In Java also, an array is a collection of similar things. Arrays are cumbersome, in most cases you are better off using the Collection API. For processing such a large amount of data, programmers need powerful data types that would facilitate efficient storage, accessing and dealing with such data items. memory must be allocated for the array) Creating Arrays type[] arrayName; declaration syntax: note the location of the [] int[] grades; // declaration grades = new int[5]; // Create array.
