What will be the output of the program?
public class Fragment18
{
static void show()
{
int smallest = Integer.MIN_VALUE;
int magnitude = Math.abs(smallest);
System.out.println(magnitude);
}
public static void main(String[] args)
{
show();
}
}
Answer: B
Integer.MIN_VALUE has no positive counterpart in the int range, so Math.abs cannot represent the answer and returns the argument unchanged, still negative. This is documented behaviour rather than a defect. Math.abs on a long would be needed to get the positive value.
