Answer:
1. the set of real numbers between 0.1 and 0.2
2. the set of all negative integers greater than negative 1 trillion
3. the set of all java and C programs
Explanation:
A set is countable if it is either finite or has the same cardinality as the set of positive integers. The inverse of this set type is uncountable.
The set of real numbers between 0.1 and 0.2, all negative integers greater than negative 1 billion, and a set of java and C programs are all countable sets, so are considered countably infinite.
