Prime Number Java Program – Java Program to Check Whether a Number is Prime or Not using different methods. The compiler has also been added so that you can execute the programs yourself, alongside suitable examples and sample outputs added for each program. Also, we will see the method of...
0 There is no reason to check above n/2. Take the number 13... you don't have to test higher then int(13/2). The higher the number, you will test more useless numbers. https://en.m.wikipedia.org/wiki/Largest_known_prime_number 25th Nov 2017, 7:23 PM Amir GalantyОтвет...
Run Code Output 29 is a prime number In this program, we have checked if num is prime or not. Numbers less than or equal to 1 are not prime numbers. Hence, we only proceed if the num is greater than 1. We check if num is exactly divisible by any number from 2 to num - 1....

本次解题使用的开发工具是eclipse,jdk使用的版本是1.8,环境是win7 64位系统,使用Java语言编写和测试。 02 第一种解法 第一步,需要先计算出整数的二进制数中1的个数,借助包装类Integer的bitCount方法来完成。 第二步,判断第一步获取的1的个数是否是一个素数,通过一个辅助方法来实现,如果是素数,计数count加1。
