I am trying to write a lab/program that loops through a .txt input file. Reads an entire line of data as a string, then splits that string into an array delimited by a space. If there are 4 items in the resulting array, and each item is a valid double, I want it to determine the distance between the points & return info to a separate output.txt file.

{CODE}

import java.io.*;

import java.util.Scanner;



public class RLabs {



    public static void main(String args) throws FileNotFoundException {

        double dealtaX, deltaY, distance,x1, y1, x2, y2;

        String Line, item1, item2, item3, item4;

        String Sect;

        Scanner inFile;

        PrintWriter outFile;



        System.out.println("I/O File Line Distance Program Starting. Opening file...");

        System.out.println("Please ensure data is entered per line in the format of (X1 Y1 X2 Y2).");

        inFile = new Scanner(new File("input.txt"));

        outFile = new PrintWriter(new File("countresults.txt"));





        while(inFile.hasNext()){



            Line = inFile.nextLine();

            Sect = Line.split(" ");

            if(Sect.length == 4) {

                item1 = Sect[0];

                item2 = Sect[1];

                item3 = Sect[2];

                item4 = Sect[3];



                if(testDoubleLow(item1,0)&&(testDoubleLow(item2,0)&&(testDoubleLow(item3,0)&&(testDoubleLow(item4,0))))){
