As we know the number zero is neither positive not negative but zero is the mid point of postive and negative integers on the number line. Similarly like whole numbers integers doesn't contain fractional part whereas there's no decimal point. In integers there is no starting point that's starting number nor the ending point number, it is because there are indefinitely numbers on both negative and positive sides.

Example:-

Positive:- 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc.

Negative:- -1, -2, -3, -4, -5, -6, -7, -8, -9, -10, etc.

Neither positive nor negative:- Zero (0).
