I need help with a java program!!?

[Jesse K]

I am writing a program that is taking a five digit number, reversing it and displaying one digit at a time. I am suppose to be using method extractNextDigit() to display the numbers one at a time. I am getting the error cannot find symbol method extractNextDigit(). I am new to programming, and my teacher is not helping at all. Here is what I have so far.

import java.util.Scanner; // program uses class Scanner

public class Project2
{

// main method begins execution of Java application
public static void main(String[] args)
{
// create Scanner to obtain imput from command window
Scanner input = new Scanner( System.in );

int number1;
int number2;
int number3;
int number4;
int number5;

System.out.print( "Number5: " );
number5 = input.extractNextDigit();

System.out.print( "Number4: " );
number4 = input.extractNextDigit();

System.out.print( "Number3: " );
number3 = input.extractNextDigit();

System.out.print( "Number2: " );
number2 = input.extractNextDigit();

System.out.print( "Number1: " );
number1 = input.extractNextDigit();

} // end main method

} // end class Project2
