Parameters are specified after the method name, inside the parentheses. You can add as many parameters as you want, just separate them with a comma.The following example has a method that takes a String called fname as parameter. When the method is called, we pass along a first name, ...
>parameter, which represents a class of any type. Hence, we pass different classes (String.class,Integer.class,Double.class) to demonstrate the flexibility of this approach. 4.
