如何限制java哈希表中的条目数？

import java.util.HashMap;

public class Main {
    public static void main(String[] args) {
        int maxEntries = 100;
        int initialCapacity = (int) (maxEntries / 0.75) + 1; // 0.75 is the default load factor
        HashMap<String, String> hashMap = new HashMap<>(initialCapacity);

        // Add elements to the hash map
        for (int i = 0; i < maxEntries; i++) {
            hashMap.put("key" + i, "value" + i);
        }

        // Attempt to add an additional element, which should trigger an exception
        try {
            hashMap.put("key" + maxEntries, "value" + maxEntries);
        } catch (IllegalStateException e) {
            System.out.println("Exception caught: " + e.getMessage());
        }
    }
}
