4 bytes
In most languages with a null reference, it is simply a memory address to a zero-length memory block. So the only memory it would occupy in these cases would be enough for a memory pointer: usually around 4 bytes.
A java.util.Date object will take about 32 bytes in memory.

An int typically occupies 4 bytes in memory on most modern systems, including those using the C and C++ programming languages. However, this can vary depending on the system architecture and the specific compiler settings. In some environments, such as certain embedded systems, an int might occupy 2 bytes or even 8 bytes. It's important to check the specifics of the platform being used.
Basically 1 kilobyte
A plain integer variable in C under windows is 2 bytes in 16 bit windows, and 4 bytes in 32 bit windows.
A kilobyte (or a k) is 1024 bytes, so 16k is 16*1024 bytes or 16384 bytes.
