2. the return type—the data type of value returned method, or void if method not return value.
3. the method name—the rules field names apply method names well, convention little different.
4. the parameter list in parenthesis—a comma-delimited list of input parameters, preceded data types, enclosed parentheses, (). if there no parameters, must use empty parentheses.
5. the method body, enclosed between braces—the method's code, including declaration of local variables, goes here.
