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 thought to myself that it was still another Sunday gone by, that Mother was now buried, that I was going to return to work and that, after all, nothing had changed.”
—Albert Camus (1913–1960)
“Chicago—is—oh well a façade of skyscrapers facing a lake, and behind the façade every type of dubiousness.”
