Help to resolve it...cant take inputs

#1

import java.util.*;

import java.util.Scanner;
public class Main {
public static void main(String args[]) {
Scanner s=new Scanner(System.in);
int n=s.nextInt();

	boolean flag = true;
	int div = 2;
	while (div <= n - 1) {
		if (n % div == 0) {
			flag = false;
			System.out.println("non prime");
			return;
		}
		div = div+1;
	}if(flag= true) {
		System.out.println("prime");
	} 

}

}

@Mudit_Rana,
https://ide.codingblocks.com/s/234186 corrected code.
I have added comments on the errors.
To take input create an object of the scanner class.

	Scanner sc = new Scanner(System.in);

Here Scanner is the class. sc is the object. For int input use: sc.nextInt()
