Prime-Adam Number in Java | ISC Computer Science 2020 Practical Specimen Paper

A Prime-Adam integer is a positive integer (without leading zeros) which is a prime as well as an Adam number.
Prime number: A number which has only two factors, i.e. 1 and the number itself.
Example: 2, 3, 5, 7, … etc.
Adam number: The square of a number and the square of its reverse are reverse to each other.
Example: If n = 13 then reverse of ‘n’ = 31
13^2 = 169
31^2 = 961 (which is reverse of 169)
