Hi, what is difference between "random access" data store (such as an array) and sequential access data (such as a linked list)? I got this doubt while reading difference between AbstractList and AbstractSequentialList, two abstract classes. Hope somebody will help me..
These terms have more to do with how elements are stored. Random Access - Is self explanatory in the sense you can access elements without worrying about how they are stored. The cost of accessing the element is always constant(independent of number of elements) Sequntial Access - You need to traverse a list to access a particular object. Depending on how the elements are stored will affect the way you access it. The cost in this case may vary from 1(case when ur searching for first element) or 'n'(case when ur searching for last element) Do post ur views if ur still not clear about it Thanks
