Difference Between HashMap and HashTable in Java | HashMap vs HashTable
HashMap is not synchronized, making it faster but not thread-safe. It allows one null key and multiple null values.
HashTable is synchronized, making it thread-safe but slower. It does not allow null keys or values.
Use Case: HashMap is ideal for non-threaded applications, while HashTable is better for legacy applications that require thread safety.
