**:**

**2, 3, 5, 7, 11, 13, 17, 19, 23**... etc. are prime numbers.

__Program:__```
import java.util.*;
public class PrimeNumber {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int count = 0,t;
System.out.println("Enter number: ");
int num = sc.nextInt();
if(num==0||num==1) {
System.out.println(num+" is not prime number");
}else {
for(int i=1; i<=num;i++) {
if(num%i==0)
count++;
}
if(count>2)
System.out.println("Given number is not prime");
else
System.out.println("Given number is prime");
}
}
}
