测试函数:编写一个主函数或测试代码来调用check_prime()函数,并传入一些数字来验证其正确性。 下面是具体的Java代码实现: java public class PrimeChecker { // 定义check_prime函数 public static boolean check_prime(int number) { // 如果数字小于2,则不是素数 if (number < 2) { return false; } ...
Trial division consists of checking if a given number, n, is divisible by any of the numbers from 2 to the square root of n. However, the method can be made more efficient by using the fact that prime numbers greater than 3 can only take on the form 6k-1 or 6k+1 where k is a...
This article looked at different ways to check if a number is prime. Apart from the custom check, we also looked at the more efficient implementation of the Java Standard Library. The code backing this article is available on GitHub. Once you'relogged in as aBaeldung Pro Member, start lear...
