Remove the " from "1000 to fix your problem

i found the solution

   
String str=jlabel.gettext();//in jlabel data is fetched from database therefore i got number format exception wher converting string to int
String g=jlabel.gettext().trim(); //now it is corect bcoz of trim()
int a=integer.parse(g);

 

thanks all

The correct way to do this is to use a try block and catch the exception if it occurs. You can't trust user input to be in the correct format!
