The java.util.Iterator is the standard Java SE interface for object that implement the Iterator design pattern. The java.lang.Iterable interface is for objects that can provide an iterator.

The HTML <table> element allows web authors to display tabular data (such as text, images, links, other tables, etc.) in a two dimensional table with rows and columns of cells.

The CREATE TABLE statement is used create a new table in the database. A table definition consists of a list of columns, their types, and any integrity constraints.
ALTER command in SQL is used to modify column/constraint in a table

The Flexible Box module, or just 'flexbox' for short, is a box model designed for user interfaces, and it allows users to align and distribute space among items in a container such that elements behave predictably when the page layout must accommodate different, unknown screen sizes. A flex container expands items to fill available space and shrinks them to prevent overflow.

Variable arguments are used by functions in the printf family (printf, fprintf, etc) and others to allow a function to be called with a different number of arguments each time, hence the name varargs.

To implement functions using the variable arguments feature, use #include <stdarg.h>.

To call functions which take a variable number of arguments, ensure there is a full prototype with the trailing ellipsis in scope: void err_exit(const char *format, ...); for example.

Foldable is the class of types t :: * -> * which admit a folding operation. A fold aggregates the elements of a structure in a well-defined order, using a combining function.

The Traversable class generalises the function formerly known as mapM :: Monad m => (a -> m b) -> [a] -> m [b] to work with Applicative effects over structures other than lists.
