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:
“I have often wondered how they manage to get return envelopes which miss, by one-quarter of an inch, fitting the blank you are supposed to return. They say, “Please fill out and return the enclosed envelope,” and the enclosed envelope is always one-quarter of an inch too small.”
—Robert Benchley (1889–1945)
“I can barely conceive of a type of beauty in which there is no Melancholy.”
—Charles Baudelaire (1821–1867)
