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");

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.

throw new RuntimeException("Test FAILED: Sets are not equal.");
}
if (hashSet.hashCode() != entrySet.hashCode()) {
