I have created a Deque in java and want to print out a string of integers, line

Question

I have created a Deque in java and want to print out a string of integers, line by line, and from a text file. I tried setting my field "number" to an integer but it printed each number out in a singular row instead of line by line. I think I can get it to print line by line if I can convert the string into an integer, so where and how do I convert it to an integer in my code below? Also, if you know a way to set the field "number" as an integer, and print line by line without having to convert it then please show me how I would go about that. Your help is greatly appreciated.

Deque my = new LinkedList(); File inputFile = new File ("file.txt"); Scanner insertion - new Scanner (inputFile) String number; while (insertion.hasNext()) number = insertion . nextLine(); my.offerFirst (number)

Explanation / Answer

please findthe java code

import java.io.File;

import java.io.FileNotFoundException;

import java.util.Deque;

import java.util.Iterator;

import java.util.LinkedList;

import java.util.Scanner;

public class DequeDemo {

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

Deque<Object> my = new LinkedList();

File inputFile = new File("File.txt");

Scanner insertion = new Scanner(inputFile);

int number;

while(insertion.hasNext()) {

number = Integer.parseInt(insertion.nextLine());

my.offerFirst(number);

}

System.out.println("Content of deque is ");

Iterator<Object> itr = my.iterator();

while(itr.hasNext())

{

System.out.println(itr.next());

}

}

}
