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:
“The chickadee and nuthatch are more inspiring society than statesmen and philosophers, and we shall return to these last as to more vulgar companions.”
—Henry David Thoreau (1817–1862)
“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)
