Please tell my mistake my test case 3 shows wrong answer

#1

import java.util.Scanner;
public class Main {
public static void main(String args[]) {
Scanner scn = new Scanner(System.in);
int N = 1;
while(N<2 && N>1000000000)
{
N=scn.nextInt();
}

	int divisor = 2;
	boolean flag = true;
	while (divisor <= N-1) {
		if (N % divisor == 0) {
			flag = false;
		}
		divisor = divisor + 1;
	}
	if (flag == true) {
		System.out.println("Prime");

	} else {
		System.out.println("Not Prime");
	}

}

}

actually ur passes some test case by mistake.

becoz initially u have initailized the N with 1
and then u taking the input in while loop which never going to execute
becoz ur N never going to >2 ( initialised N =1)

ur code will print Prime.
see the changes which i have made in ur code:

hope this will help u
and pls rate my work so that i can improve my work.

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

int divisor = 2;
boolean flag = true;
while (divisor <= N-1) {
	if (N % divisor == 0) {
		flag = false;
	}
	divisor = divisor + 1;
}
if (flag == true) {
	System.out.println("Prime");

} else {
	System.out.println("Not Prime");
}

}
}
