Methods are pre-defined blocks of code that can be called (aka invoked) by naming the method and passing an appropriate list of arguments.

• Pattern:

  methodName(argumentList);

  where:
  • methodName is the identifier naming the particular method.
  • argumentList is a list (possible empty) of items called arguments expected by the method that are in a specified order, enclosed in parentheses and separated by commas.

• As an example, consider the the following call to the user-defined computeDistance() method. This call passes arguments to the method giving the x-y coordinates of two points. The method computes and returns the Euclidean distance between those two points.
