56. Java Date Classes (util vs. sql)
    Here's a table summarizing the key differences:Why the Difference?Databases often have their own data types specifically for dates and don't handle time the same way as a general-purpose programming language like Java
57. Java SQLite Programming Connection
    Java:Offers a rich standard library with numerous classes and methods for common programming tasks.Known for its platform independence
