What will be the output of the following Java code?

class Output 
{
    public static void main(String args[]) 
    {
        long start, end;   
        start = System.currentTimeMillis();
        for (int i = 0; i < 10000000; i++);
        end = System.currentTimeMillis();
        System.out.print(end - start);
    }
}
