In the following example, we have simply created an array of length four.Once you select a zone and a difficulty level, the quest begins. Java provides the add() method to add elements in the ArrayList. ![]() ![]() We can add elements in an array by using the assignment operator. We cannot use generics along with array because it is not a convertible type of array.ĪrrayList allows us to store only generic/ type, that's why it is type-safe.Īrray provides a length variable which denotes the length of an array.ĪrrayList provides the size() method to determine the size of ArrayList. We use an iterator to iterate over ArrayList. We use for loop or for each loop to iterate over an array. It automatically converts primitive type to object. We cannot store primitive type in ArrayList. The resize operation in ArrayList slows down the performance.Īn array can store both objects and primitives type. It performs fast in comparison to ArrayList because of fixed size.ĪrrayList is internally backed by the array in Java. ![]() We can create an instance of ArrayList without specifying its size. It is mandatory to provide the size of an array while initializing it directly or indirectly. It contains popular classes like Vector, HashTable, and HashMap.Īn array is a fixed-length data structure.ĪrrayList is a variable-length data structure. The ArrayList is a class of Java Collections framework. It serves as a container that holds the constant number of values of the same type. The following table describes the key differences between array and ArrayList: BasisĪn array is a dynamically-created object.
