I do all the changes which you told me still runtime error is coming pls help me

import java.util.*;
public class Main {
/// mark all prime no
static void primeSieve(boolean prime[]) {
for (int i = 3; i < prime.length; i = i + 2) {
prime[i] = true;
}

	for (int i = 3; i*i < prime.length; i = i + 2) {
		// if the current no is marked
		if (prime[i] == true) {
			// marked all current no multiple as not prime
			for (int j = i * i ; j < prime.length; j = j + i) {
				prime[j] = false;
			}
		}
	}

	prime[2] = true;
	prime[0] = prime[1] = false;
}
// using sieve erathosthenes approach
public static void main(String args[]) {

	Scanner sc = new Scanner(System.in);

	boolean[] prime = new boolean[10000];
	primeSieve(prime);

	int T = sc.nextInt();
	
	int count = 0;
	int num = 0;

	while(T!=0) {
		int no = sc.nextInt();
		for (int i = 2; i <= prime.length; i++) {
			if (count == no) {
				break;
			} else {
				if (prime[i] == true) {
					num = i;
					count++;
				}
			}
			
		}
		no=0;
		count=0;
		System.out.println(num);
	}
}

}
