		| 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 |  |
