如何在多线程中填充数组？

import java.util.Arrays;

public class ArrayFiller implements Runnable {
    private final int[] array;
    private final int start;
    private final int end;

    public ArrayFiller(int[] array, int start, int end) {
        this.array = array;
        this.start = start;
        this.end = end;
    }

    @Override
    public void run() {
        for (int i = start; i < end; i++) {
            array[i] = i; // 填充数组的逻辑，这里简单地将索引值作为填充数据
        }
    }

    public static void main(String[] args) throws InterruptedException {
        int arraySize = 100;
        int numThreads = 4;

        int[] array = new int[arraySize];
        Thread[] threads = new Thread[numThreads];

        int chunkSize = arraySize / numThreads;
        for (int i = 0; i < numThreads; i++) {
            int start = i * chunkSize;
            int end = (i == numThreads - 1) ? arraySize : (i + 1) * chunkSize;
            threads[i] = new Thread(new ArrayFiller(array, start, end));
            threads[i].start();
        }

        for (Thread thread : threads) {
            thread.join();
        }

        System.out.println(Arrays.toString(array));
    }
}
