Can someone help me with this Java program?

 

This program is to help a student learn their prime numbers. Generate a random number (int) in the range of 1 - 200.  Ask the user if the number is a prime number.  Determine whether the number is prime (a prime number is a number that can only be divided by itself and 1) and then as output let the user know whether they were right or not.  If the number is prime, let them know that there are no numbers that will divide evenly into the number.  If the number is not prime, provide them with a list of the numbers that will divide evenly into the number. Do not list 1 or the number in that list. Be sure to ask the user if they would like to play again.  You'll use what is known as counter logic, assume the number is prime and then loop from 2 to the number minus - 1 and if any of those numbers can be divided into the number and leave no remainder, then the number is not prime.

import java.util.Scanner;
public class Main {
    public static void main(String args[]){
        Scanner sc=new Scanner(System.in);
        Random r=new Random();
        while(true){
            int n=r.nextInt(200)+1;
            System.out.print(n+" is prime or not?(Yes/No): ");
            String answer=sc.next();
            int c=0;
            for(int i=2;i<n;i++){
                if(n%i==0){
                    c+=1;
                }
            }
            if((c==0 && answer.equals("Yes")) || (c>0 && answer.equals("No"))){
                System.out.println("You are correct");
            }
            else{
                System.out.println("You are wrong");
            }
            if(c>0){
                System.out.println(n+" is not a prime number");
                System.out.print("Numbers evenly divide "+n+" are:");
                for(int i=2;i<n;i++){
                    if(n%i==0)
                    System.out.print(" "+i);
                }
                System.out.println();
            }
            else{
                System.out.println(n+" is a prime number");
            }
            System.out.print("Do you want to continue?(Yes/No): ");
            String ch=sc.next();
            if(ch.equals("No"))
            break;
