ArrayList is used to store the homogeneous elements at contiguous memory locations according to the indexes. But since the underlying implementation is an array, the array must be resized if you add a lot of elements. LinkedList, as opposed to ArrayList, does not support fast random access. ArrayList vs LinkedList both are a part of the collection framework where both are present in java.util package. 3. The default initial capacity of an ArrayList is pretty small (10 from Java 1.4 – 1.8). ArrayList is a resizable-array implementation whereas LinkedList is a Doubly-linked list implementation of the List interface. by Mario Martinez, Jan 16, 2015 | Java development. This framework defines lots of interfaces and classes for grouping objects and performing manipulations on groups such as insert, delete, sort and many more. Underlying Data Structure. Following example demonstrates the performance of add, set and remove operations using the same data on ArrayList and LinkedList. These indexes can be used to directly access the elements. In Java Collections framework there are two general-purpose List implementations— ArrayList and LinkedList.In this post we’ll see the differences between ArrayList and LinkedList in Java to understand these two implementations better. So, in order to find an element by index, we should traverse some portion of the list manually .
