The bitwise AND and OR operators (&
and |
) do not exhibit this lack short-circuit behavior. Similar to most Java operators, they evaluate both operands. They return the same Boolean result as &&
and ||
respectively but can have different overall effects depending on the presence or absence of side effects in the second operand.

This noncompliant code example, derived from Flanagan [Flanagan 2005], has two variables, with no without guarantees regarding their current values. The code must validate its data and then check whether array[i]
is a valid index.
...
This noncompliant code example demonstrates code that compares two arrays for ranges of members that match. Here i1
and i2
are valid array indices in array1
and array2
respectively. Variables end1
and end2
are expected to point to the end the indices of the ends of the matching ranges in the two arrays.

The problem with this code is that when the first condition in the while
loop fails, the second condition is does not executedexecute. That is, once i1
has reached array1.length
, the loop terminates after i1
is incremented. Consequently, the apparent range over array1
is larger than the apparent range over array2
, causing the final assertion to fail.
