Java parse a string into double

Question

How do I parse this Double in string "00034800" into a Double value? The last 2 digits are actually decimal point, so the result I am looking for is 348.00. Is there a such format I can use with Decimal Format?

@mshsayem You need 100.0 or you'll get the truncated value if it's something like "00034856" — Brian

Well...

String s = "00034800"; double d = Double.parseDouble(s) / 100.0; System.out.println(new DecimalFormat("0.00").format(d));

You may also like to catch NumberFormatException if you are not using a static string, ie from input or such

Java Double has a constructor that takes a String.

You can do:

 Double d = new Double("00034800");

And then

 double myval = d.doubleValue() / 100.0;

you can parse it as

 double d = Double.parseDouble("00034800") / 100;

and print it as

System.out.printf("%.2f", d);

You need 100.0 or you'll get the truncated value if it's something like "00034856" (how many times do I need to post this..?)
