Help running program

Question

Hello,
I am having trouble running my program in the command prompt. I got it to compile etc.
Its a program that involves inputting a list of numbers. BUt when I press "Enter" after inputting the list, nothing happens. Is there something to signify that I have stopped inputting numbers? For example, in Linux, when you press Ctrl+D, it signifies the end of the inputting of numbers and the program runs.
Any help appreciated. Thanks.

Okay, I'm using a class file, and a driver file which calls the methods.
Here is the Driver.java file
package integer;
class Driver
  public static void main(String args[])
   IntegerList list = new IntegerList();
   list.readIn( "Please input a lost of integers : " );
   list.mostCommon();
}Here is IntegerList.java
package integer;
import java.util.ArrayList;
import java.util.Scanner;
class IntegerList extends ArrayList< Integer >
// Various Methods for Manipulating a List of Integers
   //===========================================================================
   public void readIn( String prompt )
   // Output 'prompt, then input integers from 'System.in',
   // appending them, in order, onto the end of this list
      Scanner input = new Scanner( System.in );
      System.out.printf( "%s", prompt );
      while ( input.hasNext( ) )
         add( input.nextInt( ) );
   //===========================================================================
   public void writeOut( String title )
   // Output 'title' and all the values in this list on a single line
      System.out.printf( "%s", title );
      for ( int item : this )
         System.out.printf( "%d ", item );
      System.out.printf( "%n" );
   //===========================================================================
   public int count( int item )
   // Return the number of times that 'item' occurs in this list.
      int counter=0;
      for ( int num : this )
         if ( item == num )
            counter++;
      System.out.printf( "%d ", counter );
      return counter;
   //===========================================================================
   public int mostCommon( )
      int max=0;
      int result=0;
      for ( int item : this )
            result=count(item);
            if ( result > max )
                  max = result;
                  result = item;
      System.out.printf( "%d ", max );
      return max;     
   //===========================================================================
