"N/A"
is not an integer. It must throw NumberFormatException
if you try to parse it to an integer.
Check before parsing or handle Exception
properly.
- Exception Handling
try{ int i = Integer.parseInt(input); } catch(NumberFormatException ex){ // handle your exception ... }
or – Integer pattern matching –
String input=...; String pattern ="-?\\d+"; if(input.matches("-?\\d+")){ // any positive or negetive integer or not! ... }
