Converting String to double

Question:
How can I convert a String to a double and backagain?

Answer:
You can use the java.text.NumberFormat classto convert a String to a double and back again.Use the parse(String) method to convert toa double. This will actually return ajava.lang.Double wrapper class instance, soyou need to use doubleValue() to fetch thevalue of the double. To convert to a String,you can either use Double.toString(double) orNumberFormat.format(double).
