CatchProvidesOptions
Incorrect
Only the part of a catch block necessary to fix the cause of an exception is executed
Correct
When an exception is caught, all statements in the corresponding catch block execute
CorrectionHere is what's right.
Here is what's right.
Take the following example:
int moveTo(final Position p) {
moved = true;
try {
x = p.x;
y = p.y;
} catch (final NullPointerException ex) {
x = 5;
y = 8;
}
return ++steps;
}If p==null, then x=p.x throws a NullPointerException, which is caught by the catch block. Now the entire catch block executes (not only the statement fixing x by assigning it a value x=5).
