Hey guys and girls, first post here been reading for a few days but I am pretty new to java and I have to edit a class to import a file into an array. The class initially defined the array within itself. So I made my changes and I am getting a symbol not found on lines 75 and 82, in reference to inFile object of the Scanner class. Any help would be greatly appreciated, especially format criticism as I would like my future programs to be readable.

//package ChargeAccount;
import java.util.*;
import java.util.Scanner;
import java.io.*;
public class ChargeAccount {

    private int search;
    private String fileName;
    private int indexPos;
    private boolean check;
    private int sizeCount;
    private boolean fileExist;

    private int[] accounts; //modify the original array into a non final
    /*= { 
    5658845, 4520125, 7895122, 8777541, 8451277, 1302850,
    8080152, 4562555, 5552012, 5050552, 7825877, 1250255, 
    1005231, 6545231, 3852085, 7576651, 7881200, 4851002 };*/

    public ChargeAccount(){ //no arg constructor, sets search to -1 and sends toresults method
    search = 0;

    public ChargeAccount(int search, String fileName){
    //I need to define a public array here dependant on a file identified by user
    this.fileName = fileName;
    Scanner keyboard = new Scanner(System.in);

    //Used for debugging System.out.println(""+accounts.length);
    this.search = search;
    check = returnResults(search);
        System.out.println("The account "+search+" was not found");
        else {
        System.out.println("The account "+search+" was found at position: "+indexPos);

    private boolean returnResults(int search){
    if(search == 0){
        return false;
    else {
        indexPos = Arrays.binarySearch(accounts, search);
            if(indexPos != -1)
        return true;
            return false;

    //create a method that does the file validation and array creation fileToArray()
    public void fileToArray(String fileName)throws IOException{
    this.fileName = fileName;
    Scanner keyboard = new Scanner(System.in);
    //first i need to identify how many elements will be in the file
    //ill use a do while with nested if/else
        File file = new File(fileName);
        fileExist = false;
        System.out.println("File "+fileName+" does not exist, please enter a different file name with extension(*.txt)");
        //Consume the next line into fileName
        fileName = keyboard.nextLine();
        Scanner inFile = new Scanner(file);
        fileExist = true;
        //Now that we have a validated file, lets find how many elements are within
        //ill use a while to determine this
        //now we've obtained the sizeCount, we'll use that to initialize the account array
        accounts = new int[sizeCount];
        //thats done, lets add our elements
        for(int i = 0; i < sizeCount; i++){
        accounts[i] = inFile.nextInt();



Make sure the definition of the inFile variable is in scope where you are trying to use it.
In scope means defined within the same pair of {}s where it is being referenced.

Thank you NormR1, I was assuming while in the scope of the method I would be okay. Glad to get that one out of the way.
