What will be the output of the program?
public class Sample25
{
public static void main(String[] args)
{
int biggest = Integer.MAX_VALUE;
int wrapped = biggest + 1;
System.out.println(wrapped);
}
}
Answer: A
int arithmetic wraps silently on overflow rather than throwing or widening, so one past the largest int is the smallest one. The result is -2147483648. Adding 1L instead would promote the expression to long and give the mathematical answer.
