Write a for-loop with a large number of simple iterations, like this:
int a = 0;
for (int i = 0; i < 100000000; i++) {
a += i;
}
System.out.println(a);
Check how long it is executed on the usual computer. Remember how many simple iterations are done per seconds (roughly, of course).
Now imagine the loop with seemingly stupid condition i > i + 1, like this:
int i = 0;
while (true) {
if (i > i + 1) {
break;
}
i++;
}
System.out.println(i);
How long it will take to finish (roughly)?
What number would be printed at the end?
How long it will take if we change the type of i to long (probably you will not be able to check this by direct experiment so you need to be cunning enough).
