When working with dates and times in Java, you may often need to convert a LocalDateTime object into a long timestamp, typically representing the number of milliseconds or seconds since the Unix epoch (January 1, 1970, 00:00:00 UTC). This can be useful for database operations, APIs, or any scenario requiring a numerical representation of date and time. Step-by-Step Conversion ProcessJava’s LocalDateTime is a part of the java.time package introduced in Java 8. Since LocalDateTime is time-zone...

Bitmaps are not an actual data type, but a set of bit-oriented operations defined on the String type which is treated like a bit vector. Since strings are binary safe blobs and their maximum length is 512 MB, they are suitable to set up to 2^32 different bits. You can perform bitwise operations on one or more strings. Some examples of bitmap use cases include: Efficient set representations for cases where the members of a set correspond to the integers 0-N. Object permissions, where each...
