Reason for the existence of non-short-circuit logical operators

Question

When used with boolean operands, & and | become logical operators per Section 15.22.2 of the JLS. Unlike &&

Answer 1

You can have some side-effects in logical expression, for example you can assign simultaneously with checking. This may work wrongly if only one part evaluated.

Can't remember good example now, but remember that I was in need of "non-short-circuit" operators sometimes.

Hmmm.... Below is WRONG example, which won't work without "non-short-circuit" OR:

if( (object1=getInstance1()).getNumber() == 1 || (object2=getInstance2()).getNumber() == 2 ) {

    // do something which requires bot object1 and object2 assigned

}
