How to convert string value into int? I am getting number format exception.

String s = "20.00";
int i = (Integer.parseInt(s));
System.out.println(i);

Result should be like i=20.

Answer 1

What about:

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

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

Answer 2

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.

i.e. int I = (int) Double.parseDouble(str);
