Ginny, look up NumberFormat or DecimalFormat classes. You instantiate
one of these using a format pattern and can then use the object to
parse strings of numbers as well as formatting them for display. I
expect you could devise a format pattern string which will do what you
want in handling the zeroes.

Some relevant coding:
DecimalFormat vDF = new DecimalFormat("###0.0000");
String vFactorString = "123.4567";
Double vFactor = vDF.parse(vFactorString,new ParsePosition(0));
double vTemp = vFactor.doubleValue();
