Set of all integers less than 5. Finite set or infinite set

Dear student,
Integers are whole-valued positive or negative numbers or 0.
So, a set of integers can be described as 
{1,2,3,4,5,6,7....}$\cup${0} $\cup${-1,-2,-3,-4,-5,-6,-7..}
Thus,
Set of all integers less than 5
={.....-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4}
clearly the set is infinite set.

Regards!
