It is not logical but numerical operator in this case. Indeed,

System.out.println( 4 || 7);

does not even compile.

Gooc old C does not have a logical (boolean) type, it uses integers on the syntax level too. C++ has the "bool" type, but it maintains the logical <-> integer conversion.

In java the logical type is separated from the integral ones; there is no boolean -> integer conversion.

For convenience however single & and | can be applied to booleans.
