Indentation levels should always correspond to the logical flow :
if (rareCondition)
rareAction();
action();
You would never write it this way :
if (rareCondition)
rareAction();
action();
But this is what we do with try-catch clause.
I found an alternative indentation (see below) in one of the java magazines.
It's so simple it's beautiful. So obvious. So effective.
After using for a week, I can't imagine writing a single try-catch clause the
old way.
Before (the standard way)
------
try {
doStep1ThatCouldFail () ;
doStep2() ;
} catch (SomeException e){
doThisOnlyIfSomethingFailed() ;
} finally {
allwaysDoThis ();
}
After (the reverse indentation way)
-----
try {
doStep1ThatCouldFail () ; // line *1
doStep2() ;
} catch (SomeException e){
doThisOnlyIfSomethingFailed() ;
} finally {
allwaysDoThis ();
}
Move back 30cm, and look at both pieces of code.
Which one makes the more sense to you?
Problem :
1� typing [return] at the end of line*1 will not put the cursor at the
expected level.
2� IDEA source format does not support this alternative indentation.
