Issue
I was reading this, advantages of java, where it states that random access is an advantage of arrays in java. I do not understand how can accessing a random element of an array is an advantage. Shouldn't it be a disadvantage?
Why is java allowing to access elements of an array randomly, if the data is stored continuously, shouldn't the data be accessed in an orderly manner?
Solution
Random(direct) access implies the ability to access any entry in a array in constant time (independent of its position in the array and of array's size). And that is big advantage.
It is typically contrasted to sequential access. Datastructure has sequential access if we can only visit the values it contains in one particular order.
