'Dive into Python' has a very memorable and interesting section on the
exact behaviour of 'and' and 'or' in Python:

No: &, | (and ^, too) perform bitwise operations in Python, C and Java:
"In complete evaluation ... both expressions are always evaluated. To
obtain complete evaluation in Java, you use & rather than && ... and
use | in place of ||" - Walter Savitch, Absolute Java 2nd ed.
Although & IS the bitwise-AND operator in Java:
http://java.sun.com/docs/books/tutorial/java/nutsandbolts/operators.html
I guess it's a matter of context.
Java has a bool type that's distinct from the int type. &, | and ^ are
bitwise for int and Boolean for bool, and in both cases they are strict.
&& and || are for bool only and they are lazy.
In Pascal the behaviour of "and" and "or" is implementation-dependant...
