What about:

int i = (int) Double.parseDouble(s);

Of course, "20.00" is not in a valid integer format.

String s = "20.00";

is not valid Integer value that is the reason its throwing NumberFormatException .

Format your number using either Double or Float then using narrow casting cast you number to int but you may loose precision if exists.

ie int I = (int) Double.parseDouble(str);
