Logical (AND, OR, XOR) over Long

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?

Maybe they wanted to implement IDL-like logical operators

Default Definitions of True and False

Data Type                    True                              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

You can apply bit-wise operators on longs:

  • & is AND
  • | is OR
  • ^ is XOR

What do you mean by not possible? 3 | 4 | 5 is a perfectly valid expression as 3 & 4 & 5.
