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. It is possible to iterate over an array using the for-each loop, though java arrays do not implement Iterab...
$variable = 'value'; // Assign general variable $object->property = 'value'; // Assign an object property ClassName::$property = 'value'; // Assign a static class property $array[0] = 'value'; // Assign a value to an index of an array $array[] = 'value'; // Push an item at the end of an ar...
global a, b, c nonlocal a, b x = something # binds x (x, y) = something # binds x and y x += something # binds x. Similarly for all other "op=" del x # binds x for x in something: # binds x with something as x: # binds x except Exception as ex: # binds ex inside block ...
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. <table></table> <thead></thead> <tbody></tbody> <tfoot></tfoot&...
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. CREATE TABLE tableName( [ColumnName1] [datatype1] [, [ColumnName2] [datatype2] ...] ) ParameterDetailstableNameThe name of the ...
ALTER command in SQL is used to modify column/constraint in a table ALTER TABLE [table_name] ADD [column_name] [datatype]
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 containe...
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 ca...
Tables are supported only in certain flavors of Markdown, including Markdown Extra and Github Flavored Markdown, but not in the original Markdown syntax or in CommonMark. Markdown tables are also not supported on Stack Exchange sites (with the exception of the Documentation beta).

When testing, it is sometimes useful to use a test double to manipulate or verify the behaviour of the system under test. The doubles are passed or injected into the class or method under test instead of instances of production code.
Some languages require you to define ahead of time what kind of variable you're declaring. JavaScript doesn't do that; it will try to figure that out on its own. Sometimes this can create unexpected behavior. If we use the following HTML <span id="freezing-point">0</span> ...
var x int // declare variable x with type int var s string // declare variable s with type string x = 4 // define x value s = "foo" // define s value y := 5 // declare and define y inferring its type to int f := 4.5 // declare and define f inferring its type to float64 b := &quo...

In MongoDB 3.0, MMAP (default) and WiredTiger are the stable storage engines. Usually, if your app is read-heavy, use MMAP. If its write-heavy, use WiredTiger. Your solution may also have a mixed replica set members where you can have one node configured with MMAP and another with WiredTiger. Yo...

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. If t is Foldable it means that for any value t a we know how to access all of the elements of a from "inside&qu...
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.
