part :- 09 || Java Prime Number Checker Tutorial with User Input || Java Programming for Beginners

The Prime class contains a main method, which serves as the entry point for the program. Within the main method:

It prompts the user to enter a number by displaying the message "Enter Your Number".
It reads the input integer using the Scanner object scn.
It then iterates t times, where t is the entered number.
Within each iteration, it prompts the user again to enter a number.
It reads the entered number into the variable n.
It initializes a boolean variable isprime to true, assuming initially that the number is prime.
It initializes a divisor div to 2 and enters a while loop where it checks if the square of div is less than n.
Within the loop, it checks if n is divisible by div. If it is, it sets isprime to false and breaks out of the loop.
If isprime remains true after the loop, it prints "prime", indicating that the number is prime. Otherwise, it prints "not prime".
Overall, this program efficiently determines whether a given number is prime or not by iterating through potential divisors up to the square root of the number.
