Question

Write a static method named lowestPrice that accepts as its parameter a Scanner for an input file. The data in the Scanner represents changes in the value of a stock over time. Your method should compute the lowest price of that stock during the reporting period. This value should be both printed and returned as described below.

Answer 1

Answer:

Explanation:

The following code is written in Java. It creates the method as requested which takes in a parameter of type Scanner and opens the passed file, reads all the elements, and prints the lowest-priced element in the file. A test case was done and the output can be seen in the attached picture below.

import java.io.File;

import java.io.FileNotFoundException;

import java.util.Scanner;

class Brainly{

   public static void main(String[] args) throws FileNotFoundException {

       Scanner console = new Scanner(System.in);

       System.out.print("file location: ");

       String inputLocation = console.next();

       File inputFile = new File(inputLocation);

       Scanner in = new Scanner(inputFile);

       lowestPrice(in);

   }

   public static void lowestPrice(Scanner in) {

       double smallest = in.nextDouble();

       while(in.hasNextDouble()){

           double number = in.nextDouble();

           if (number < smallest) {

               smallest = number;

           }

       }

       System.out.println(smallest);

       in.close();

   }

}
