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:
“Our needs hourly
Climb and return like angels.
Unclosing like a hand,
You give for ever.”
—Philip Larkin (19221986)
“Music, in performance, is a type of sculpture. The air in the performance is sculpted into something.”
—Frank Zappa (19401994)
