Count Prime Numbers

[niloufar]

I have to count, how many prime numbers exist, but it give me wrong answer: Exactly 1254 prime numbers exist between 1 and 10,000.

can you tell me why? Thank you!

// Verify Prime Number
					private static boolean isPrime(int prime) {
						for(int i = 2; i < Math.sqrt(prime) ; i++) {
				            if ((prime % i) == 0) {
				            	return false;
				             }
							  
				           }
						return true;
				     }
				    
						
					// Calculate Prime
					private static int countPrimes(int number){
						int count =0;
												
						for(int i=2; i<=MAX_PRIME; i++)	{
							if(isPrime(i)){
							count++;
							}
										
					}
					System.out.println("Exactly "+  count + " prime numbers exist between "+number + " and 10,000.");
					return count;	
									
					}
