Return Statements

Execution of a return statement terminates execution of the method body and, hence, of the method call. The return statement in the body of a function differs from the return statement in a procedure or constructor. See below.

The procedure and constructor bodies

When a procedure or constructor is called, the statements in its body are executed one at a time, in the order in which they appear. During this execution, execution of the statement:


terminates execution of the body, and thus of the procedure or constructor call —no further statement in the body is executed, once a return-statement is executed. A return-statement need not be included in the body of a procedure or constructor, but sometimes a body may be easier to write using a return-statement.


The function body

A function call yields a value. Therefore, execution of a function body must terminate by executing a return-statement of the form

return <expression> ;

where the type of the <expression> is the same as (or narrower than) the type of the result of the function. Execution of such a return-statement terminates the function body, and, thus, the function call, and yields the value of the<expression> as the result of the call.

Since execution of a function body must terminate with execution of a return-statement, the last statement of a function body is usually a return-statement. However, return-statements may appear in other places as well.
