Default constructor
open-in-new
<p>In computer <a href="/facts/Programming_languages/cWTYbgWa">programming languages</a>, the term default constructor can refer to a <a href="/facts/Constructor_(computer_science)/8JNHsH5H">constructor</a> that is automatically generated by the compiler in the absence of any programmer-defined constructors (e.g. in Java), and is usually a <a href="/facts/Nullary_constructor/Yok4sanz">nullary constructor</a>. In other languages (e.g. in C++) it is a constructor that can be called without having to provide any arguments, irrespective of whether the constructor is auto-generated or user-defined. Note that a constructor with formal <a href="/facts/Parameter_(computer_science)/LcuLbbSq">parameters</a> can still be called without arguments if <a href="/facts/Default_argument/WmF2e6Ha">default arguments</a> were provided in the constructor's definition. </p>
