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:
“We must return optimism to our parenting. To focus on the joys, not the hassles; the love, not the disappointments; the common sense, not the complexities.”

“Lise: Look, monsieur, I don’t know what type of girl you think I am, but I’m not. And now I would like to return to my friends.
Jerry: I thought you were bored with them. You sure looked it.
Lise: You should see me now.
Jerry: Ouch.”
—Alan Jay Lerner (1918–1986)
