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:
“It is the secret of the world that all things subsist and do not die, but only retire from sight and afterwards return again.”
—Ralph Waldo Emerson (18031882)
“We have two kinds of conference. One is that to which the office boy refers when he tells the applicant for a job that Mr. Blevitch is in conference. This means that Mr. Blevitch is in good health and reading the paper, but otherwise unoccupied. The other type of conference is bona fide in so far as it implies that three or four men are talking together in one room, and dont want to be disturbed.”
—Robert Benchley (18891945)
