## Prime Number Finder In Java

A prime number (or a prime) is a natural number which has exactly two distinct natural number divisors: 1 and itself.
This small program runs through 2-500 and print all the prime numbers in that range.

Note: The number 1 is by definition not a prime number.

```package com.kushal.utils;

/**
* Method to test whether a number is
* a prime number or not
*/
public static boolean isPrimeNumber(int number) {
boolean prime = true;
int limit = (int) Math.sqrt(number);

for (int i = 2; i <= limit; i++) {
if (number % i == 0) {
prime = false;
break;
}
}

return prime;
}

public static void main(String[] args) {

/**
* Loop From 2-500 and Print all the prime numbers
*/
System.out.println("List Of Prime Numbers From 2-500");
for (int i = 2; i <= 500; i++) {
{
System.out.println(i);
}
}
}
}
```
