Answer 1

First line in your execption:

Exception in thread "AWT-EventQueue-0" java.lang.NumberFormatException: For input string: "4.5.5255"

It means you are trying to parse 4.5.5255 which is not a number.

It's hard to tell in which line in your code you get this exception.[may be at sanskarwani.java:3667]. I mean in the code you have posted how can we find line number 3667. Try to debug your code and post the code where the error occurred separately.

Answer 2

you are trying to format a decimal in string format containing floating point to integer.

int types should not have floating points.

you can convert this string to integer:

455255

but this is not a correct integer:

4.5.5255

try this :

string number = "4.5.5255";
number = number.replace(".", "");
Integer.parseInt(number );
