How to call the methods of an object

• To call a method that doesn't accept arguments, type an empty set of parentheses after the method name.
• To call a method that accepts arguments, enter the arguments between the parentheses that follow the method name, separated by commas.
• The data type of each argument must match the data type that's specified by the method's parameters.
• If a method returns a value, you can code an assignment statement to assign the return value to a variable. The data type of the variable must match the data type of the return value.
