In the case of JAVA do not know how much of the amount of data to enter the end input

The INPUT = new new Scanner Scanner (System.in);
 System.out.print ( "Please enter a number :( finally enter the end !!)"); 
String Line = input.nextLine (); 
Scanner INPUT1 = new new Scanner (Line) ;
 the Node the Node new new E = (); 
the while (input1.hasNext ()) { 
    e.add (E, input1.nextInt ()); 
} 
provided two first Scanner reads data in units, so that the equivalent of a carriage return (Enter) as a terminator, 
and then to read the second character string passed Scanner, and then processing is performed
