Test prime number in java
WebHow to find a prime number in Java Take a number as input. Check if there is a divisor of the number in the range of [two, number/2] because two is the smallest prime number. There is no number that can be completely divided by more than half of the number itself. We need to loop through two to the number itself divided by two (number/2).
