This Java program checks if a number is prime by testing divisibility from 2 to the square root of the number.
A prime number is greater than 1 and has no divisors other than 1 and itself.
To check if a number 'n' is prime, iterate from 2 to sqrt(n).
If 'n' is divisible by any number in this range, it is not prime.
Example: 5 is prime (divisors: 1, 5), but 4 is not (divisors: 1, 2, 4).
