Hi @iluwatar , There is a small casting issue.

Hi @MaheshMadushan @iluwatar .
I'm beginner in java and during learning the java literals , I encountered one nice point which address this issue .
In java integer literal can always be assigned to a long variable . However , to specify a long literal you will need to explicitly tell the compiler that the literal value is of type long . We can do this by appending an uppercase or lowercase L to the literal .
Here in this case we have variable futureTime as type of long type but the literal assigned to it is of type integer . So here compiler first do the casting of 1000 * 1000 * 1000 * 1000 to an integer literal and then assigned it to futureTime .
Solution to this problem is to use the long literal.
For example :

• 1000L * 1000 * 1000 * 1000
• 1000 * 1000L * 1000 * 1000
• 1000 * 1000 * 1000L * 1000
• 1000 * 1000 * 1000 * 1000L
  These are few valid long literal we can use ( we can also use variation like 1000000000000L ) .
  I hope you got my point here .
