In computer programming, the return type (or result type) defines and constrains the data type of the value returned from a subroutine or method. In many programming languages (especially statically-typed programming languages such as C, C++, Java) the return type must be explicitly specified when declaring a function.
In the Java example:
public int someMethodthe return type is int. The program can therefore rely on the method returning a value of type int. Various mechanisms are used for the case where a subroutine does not return any value, e.g., a return type of void is used in some programming languages:
public void returnNothingFamous quotes containing the words return and/or type:
“We wished our two souls
might return like gulls
to the rock. In the end,
the water was too cold for us.”
—Robert Lowell (1917–1977)
“Writing is more than anything a compulsion, like some people wash their hands thirty times a day for fear of awful consequences if they do not. It pays a whole lot better than this type of compulsion, but it is no more heroic.”
—Julie Burchill (b. 1960)
