Omg, after hours of rage. I found out list's can't be used to access individual element.
This list class, unlike the vector class, is not designed for solutions that require a data structure for efficient individual element access. The ends of the list are accessed in an optimal way, O(1). However, all other access requires O(n) operations or O(lgn) when the list is sorted. In addition, there are no indices for the elements in a list. However, an elements position within the list can be obtained using iterators and the distance(start_itr, current_pos_itr). The following table describes individual element access expressions:
I am writing a java program that needs to execute shell commands, so I wrote a function that would take the command to execute as a string (ie: "mkdir ~/Folder1") and execute that command with the shell. Here is the function:
Runtime run = Runtime.getRuntime();

Hi, as I was told that my code doesn’t scale well at all, I thought perhaps I’d try to get a better understanding of interfaces/abstract classes and classes and the relationship between them.
I don’t want at this stage work on a big separate project as I've already got plenty ...
