| Description |
Keyword used to indicate the value to return from a function. The value being returned must be the same datatype as defined in the function declaration. Functions declared with void can't return values and shouldn't include a return value. The keyword return may also be used to break out of a function thus not allowing the program to read the remaining statements (see the third example above). |
| Syntax |
type function {
statements
return value
} |
| Parameters |
| type |
boolean, byte, char, int, float, String, boolean[], byte[], char[], int[], float[], String[] |
| function |
a function that is being defined |
| statements |
any valid statements |
| value |
must be the same datatype as the type parameter |
