Question

I am extending a tool in Java that somehow is capable of applying Logical (AND, OR and XOR) over three Long values.

How is that possible? If it is possible?

Answer 1

Maybe they wanted to implement IDL-like logical operators

Default Definitions of True and False

Byte,integer, and long       Odd integers                      Zero or even integers 
Floating point and complex   Non-zero values                   Zero 
String                       Any string with non-zero length   Null string (" ") 
Heap variables               Non-null values                   Null values
