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)
“It is not true that there is dignity in all work. Some jobs are definitely better than others.... People who have good jobs are happy, rich, and well dressed. People who have bad jobs are unhappy, poor and use meat extenders. Those who seek dignity in the type of work that compels them to help hamburgers are certain to be disappointed.”
—Fran Lebowitz (b. 1950)
