示例1: main

import java.util.HashSet; //导入方法依赖的package包/类
public static void main(String[] args) throws Exception {
    final ConcurrentHashMap<String, String> concurrentHashMap =
        new ConcurrentHashMap<>();

    concurrentHashMap.put("One", "Un");
    concurrentHashMap.put("Two", "Deux");
    concurrentHashMap.put("Three", "Trois");

    Set<Map.Entry<String, String>> entrySet = concurrentHashMap.entrySet();
    HashSet<Map.Entry<String, String>> hashSet = new HashSet<>(entrySet);

    if (false == hashSet.equals(entrySet)) {
        throw new RuntimeException("Test FAILED: Sets are not equal.");
    }
    if (hashSet.hashCode() != entrySet.hashCode()) {
        throw new RuntimeException("Test FAILED: Set's hashcodes are not equal.");

示例2: main

import java.util.HashSet; //导入方法依赖的package包/类
public static void main(String[] args) throws Exception {
    final IdentityHashMap<String, String> identityHashMap =
        new IdentityHashMap<>();

    identityHashMap.put("One", "Un");
    identityHashMap.put("Two", "Deux");
    identityHashMap.put("Three", "Trois");

    Set<Map.Entry<String, String>> entrySet = identityHashMap.entrySet();
    HashSet<Map.Entry<String, String>> hashSet = new HashSet<>(entrySet);

    // NB: These comparisons are valid in this case because none of the
    //     keys put into 'identityHashMap' above are equal to any other.
    if (false == hashSet.equals(entrySet)) {
        throw new RuntimeException("Test FAILED: Sets are not equal.");
    }
    if (hashSet.hashCode() != entrySet.hashCode()) {
        throw new RuntimeException("Test FAILED: Set's hashcodes are not equal.");
