We want to find the average of three positive numbers (doubles). Consider the following class (which is not complete): // Program finds the minimum of 3 positive numbers import java.util.Scanner; public class Lab5 { // find the minimum of three numbers public static void main(String[ ] args) Scanner input - new Scanner (System.in); double one; // first number double two; // second number double three; // third number System.out.printf("%s " , "Enter a positive number or type Q to terminate" while (true) one - getInput (input): // Write code to get the remaining inputs and // if a negative value is entered. // Write code to display the minimum of the three // floating-point numbers * } // end whilee l // end main // the minimum method determines the smallest of three numbers // complete the header for the minimum method // that takes three double parameters and returns a double public static minimum () // Add code to compute and return the minimum of three numbers ) // end method minimum // the getInput method prompts the user for input and // returns a number entered by the user or -1 if a negative number // or if something else is entered. public static double getInput (Scanner input) // Add code to prompt and return the user's input } // end method getInput 1. Complete the getInput method to prompt the user and return the user's input or a -1 if he enters something other than a number 2. Add the appropriate code in the while loop to input the remainder of the input data using the getInput method or exiting the program whenever a negative value is returned. 3. Complete the header of the three parameter minimum method shown above Write the code that returns the smallest value and outputs that value 4
