Answer to Question #111766 in Java | JSP | JSF for Stephen

Question

Discuss the concept of parameters. What are parameters for? What is the difference between formal parameters and actual parameters? Give an example in Java code that illustrates formal parameters and actual parameters.

Answer 1

formal parameter - an argument specified when declaring or defining a function.

actual parameter is the argument passed to the function when it is called.

public double myFunction(int a,double b)// int a, double b - formal parameters of the myFunction method
{
//do something
}

public static void main(String[] args) {

myFunction(5, 3.14); // 5, 3.14 - actual parameters of the myFunction method

}
