Will memory be allocated

[faisal usmani]

Hello ranchers ,

If we write

int a[] = new int[10];

we know 40 bytes of memory will be allocated .

but what if i write

int a[] = new int[0] ;

will memory be allocated , if yes why ?


Thanks in advance

Your basic assumption is invalid. You don't know that 40 bytes will be allocated -- you know that more than 40 bytes will be allocated, but you don't know how much more. A zero-element array does indded have a finite size, but the size is dependent on the JVM implementation, not something you can find out from the Java language itself.
