add a function/method Sum, that takes two parameters and returns a sum. Show how to CALL this method and get a sum out of it. Please use pseudocode or Java to do that.

import java.util.Scanner; public class Methods2 { public static double average(double p1, double p2) { double ave; ave=(p1+p2)/2; return ave; }//end of average public static void main(String [] arg) { System.out.printf(" Hello from main"); Scanner keyboard=new Scanner(System.in); double num1, num2; System.out.printf(" Please enter number one:"); num1=keyboard.nextDouble(); System.out.printf(" Please enter number two:"); num2=keyboard.nextDouble(); double result; // the average is called // the return value is assigned to "result" result=average(num1, num2); System.out.printf(" The result is %f", result); }//end of main }//end of Methods2
