无法将大量素数打印到控制台

Question

public class PrimeFinder implements Runnable {
    Thread go;
    StringBuffer primes = new StringBuffer();
    int time = 0;
    
    public PrimeFinder() {
        start();
        while (primes != null) {
            System.out.println(time);
            try {
                Thread.sleep(1000);
            } catch (InterruptedException exc) {
                // do nothing
            }
            time++;
        }
    }
    
    public void start() {
        if (go == null) {
            go = new Thread(this);
            go.start();
        }
    }
    
    public void run() {
        int quantity = 1_000_000;
        int numPrimes = 0;
        // candidate: the number than might be prime
        int candidate = 2;
        primes.append("\nFirst ").append(quantity).append(" primes:\n\n");
        while (numPrimes < quantity) {
            if (isPrime(candidate)) {
                primes.append(candidate).append(" ");
                numPrimes++;
            }
            candidate++;
        }
        System.out.println(primes);
        primes = null;
        System.out.println("\nTime elapsed: " + time + " seconds");
    }
    
    public static boolean isPrime(int checkNumber) {
        double root = Math.sqrt(checkNumber);
        for (int i = 2; i <= root; i++) {
            if (checkNumber % i == 0) {
                return false;
            }
        }
        return true;
    }
    
    public static void main (String[] arguments) {
        new PrimeFinder();
    }
}

我假设eclipse中存在一些限制，阻止将大量数字打印到控制台。

编辑：在5572处，控制台的输出将被清除，这是输出：

你想看多少个素数？5572

您的控制台输出可能是有限的。在日食中，得...
