Java long primitive type maximum limit

Question

Here’s my code below:

class LongTest {

   private static long increment;

   public static long generateNumber(){

       ++increment;

       return increment;

   }

}

It calls the 'generateNumber'method which will increment my long data type by 1. Can anyone tell me what I should do when it reaches its maximum limit? 

Answer 1

Even if you execute the function once per nanosecond, it’ll take around 292 years(refer here) for the long data type to be fully used up. Since Long.MAX_VALUE is 9,223,372,036,854,775,807. If the overflow happens, you can wrap it to Long.MIN_VALUE
