In computer programming, duplicate code is a sequence of source code that occurs more than once, either within a program or across different programs owned or maintained by the same entity. Duplicate code is generally considered undesirable for a number of reasons. [ 1 ]
Release versions of Flutter apps on all platforms use ahead-of-time (AOT) compilation [22] except for on the Web where code is transpiled to JavaScript or WebAssembly. [ 23 ] [ 24 ] Flutter inherits Dart's Pub package manager and software repository , which allows users to publish and use custom packages as well as Flutter-specific plugins. [ 25 ]
In computer programming, indentation style is a convention, a.k.a. style, governing the indentation of blocks of source code.An indentation style generally involves consistent width of whitespace (indentation size) before each line of a block, so that the lines of code appear to be related, and dictates whether to use space or tab characters for the indentation whitespace.
"Don't repeat yourself" (DRY), also known as "duplication is evil", is a principle of software development aimed at reducing repetition of information which is likely to change, replacing it with abstractions that are less likely to change, or using data normalization which avoids redundancy in the first place.
In software engineering and programming language theory, the abstraction principle (or the principle of abstraction) is a basic dictum that aims to reduce duplication of information in a program (usually with emphasis on code duplication) whenever practical by making use of abstractions provided by the programming language or software libraries.

A study from the University of Maryland found that Android developers that used only Stack Overflow as their programming resource tended to write less secure code than those who used only the official Android developer documentation from Google, while developers using only the official Android documentation tended to write significantly less ...
In object oriented programming, objects provide a layer which can be used to separate internal from external code and implement abstraction and encapsulation. External code can only use an object by calling a specific instance method with a certain set of input parameters, reading an instance variable, or writing to an instance variable.
I suppose pretty much all countries will have some coal, gas or oil. Whether that is commercially interresting and actually exploited is a different matter. You might look at opec, List of oil fields and List of natural gas fields. DirkvdM 10:36, 2 December 2005 (UTC) Also several countries have big biofuel resources (ie big forests).
