Default value in while loop

[UmairBaloch]

I'm supposed to make a program that reads an integer between two given limits and determines if it's prime or composite. I've made this program using while loop and it runs successfully, what I want to do is that if I enter an integer outside the limits, it must show a message "The number is not valid"
code is

import java.util.Scanner;

class Pri{
	public static void main(String a[]){
		Scanner scan = new Scanner(System.in);
		
		System.out.print("Enter the Starting limit: ");
		int strlmt = scan.nextInt();
		
		System.out.print("Enter the Ending limit: ");
		int endlmt = scan.nextInt();
		
		System.out.print("Enter any number between given limit: ");
		int num=scan.nextInt();
		int count = 2, check = 0;
while (count<=num){
		if (num%count==0)
			check++;
			count++;
		}
		if (check>1)
		System.out.print("The number is Composite");
		else
		System.out.print("The number is Prime"); 

}
}

I've tried (num<strlmt && num>endlmt);
System.out.println("the number is not valid");

but I dont know how to put this in loop
Thanks.

Use OR instead AND in this case. You can't have a number smaller then the start limit and bigger then the end limit at the same time.
