find the nearest prime number in java The closest prime can be greater or smaller than the passed input integer. If there are equi-distant prime-numbers, print both. Example: Input#1: 32 Output#1: 31 Input#2: 30 Output#2: 29 31 Code:: import java.util.Scanner; public class Test { public static void main(String[] args) { Scanner scn = new Scanner(System.in); int n = scn.nextInt(); find(n); } public static void find(int num) { // greater number int num1 = num + 1; while (true) { if (isPrime(num1)) { break; } num1++; } // smaller int num2 = num - 1; while (num2 > 1) { if (isPrime(num2)) { break; } num2--; } // System.out.println(num1+" "+num2); if (num2 == 1) { System.out.println(num1); } else if (num1 - num == num - num2) { System.out.println(num2 + " " + num1); } else if (num1 - num < num - num2) { System.out.println(num1); } else { System.out.println(num2)
