获取guava多重集中元素的实例数而不进行迭代

import com.google.common.collect.HashMultiset;
import com.google.common.collect.Multiset;

public class Main {
    public static void main(String[] args) {
        Multiset<String> multiset = HashMultiset.create();
        multiset.add("apple");
        multiset.add("banana");
        multiset.add("apple");
        multiset.add("orange");
        multiset.add("banana");

        // 获取元素的实例数
        int appleCount = multiset.count("apple");
        int bananaCount = multiset.count("banana");
        int orangeCount = multiset.count("orange");

        System.out.println("apple count: " + appleCount);
        System.out.println("banana count: " + bananaCount);
        System.out.println("orange count: " + orangeCount);
    }
}

apple count: 2
banana count: 2
orange count: 1
