Importing and sorting text file

Question

I am importing a text file. Now i need to run and if function, so I can sort the text data between positive and negatives.
import java.util.Scanner;               //Needed for Scanner Class
import java.io.*;                              // Java API Class that allows you to import files
The Transactions.java program was designed to import text file (transactions, sort
the data with values of "<= 0" and ">=1" as withdrawals and deposits respectively.
Then the program will output the data into two different text files: Deposits.txt
and Withdrawals.txt.
public class Transactions
public static void main (String[] args) throws IOException
String display = "test";
     //Create a Scanner object for keyboard input.
Scanner keyboard = new Scanner(System.in);
     //Get the file name.
System.out.print("Please enter the name of the file you are trying to acces:");
String filename = keyboard.nextLine();
     //Open the file.
File file = new File(filename);
Scanner inputFile = new Scanner(file);
          //Read lines from the file until none are left.
while (inputFile.hasNext())
          //Close the file
inputFile.close();
}

the program will call a text file. the text file has a range of numbers. from negative to positives. i can get the program to import the data; however, i need these data to be sorted by <= 0 & >= 1When you read the lines from the text file they will be read as Strings. You will need to parse those Strings to a number (Integer or Float/Double depending on if the numbers are whole numbers or decimals). The Double and Integer API pages give you the methods you need to use to convert the String to the correct number.
