| | 3 | The '''return''' statement terminates execution of the method in which it appears and returns control to the calling method. |
| | 4 | |
| | 5 | The value of the expression clause is returned to the calling function converted to the type specified in the method declaration.[[BR]] |
| | 6 | Constructors and destructors, and functions of type void, cannot specify an expression in the return statement.[[BR]] |
| | 7 | Functions of all other types must specify an expression in the return statement |
| | 8 | |
| | 9 | If the return statement is inside a try block, the finally block, if one exists, will be executed before control returns to the calling method. |
