NumberFormat Parse gives incorrect result for comma separator

Question

I have a string 1,5 and i am creating NumberFormat with US locale. I expect NumberFormat.parse method to give me exception for string 1,5 string. But it doesn't. The result is 15 for 1,5 string. Please help.
I have a class where i did test. I have tried 3 cases. All 3 cases didn't work. Any idea how to solve it?
import java.util.*;
import java.text.*;
public class testv
     public static void main(String[] args)
          DecimalFormatSymbols symbols = new DecimalFormatSymbols(Locale.US);
          System.out.println("Decimal separator: "+symbols.getDecimalSeparator());
          System.out.println("Group separator: "+symbols.getGroupingSeparator());
          String s = "1,5";
          NumberFormat fmt = NumberFormat.getInstance(Locale.getDefault());
          Number num = null;
          try
               //start of case 1*********
               num = fmt.parse(s);
               //end of case 1************ desn't work
               //start of case 2*********
               /*ParsePosition parsePosition = new ParsePosition(0);
               num = fmt.parse( s, parsePosition);
               if (! ((parsePosition.getIndex()) == ( s.length() )) )
                    throw new ParseException("parseerror",0);
               //end of case 2*********          desn't work     
               //start of case 3*********
               /*if (fmt instanceof DecimalFormat)
                    ParsePosition parsePosition = new ParsePosition(0);
                    num = fmt.parse( s, parsePosition);
                    if (! ((parsePosition.getIndex()) == ( s.length() )) )
                         throw new ParseException("parseerror",0);
               //end of case 3************ desn't work
          catch (Exception e)
               e.printStackTrace();
          System.out.println("Parse string: "+s+" result: " + num.toString()+" result in double: "+num.doubleValue()+" locale: "+Locale.getDefault());
     }
