What is the ideal length of a Java File?
[205 byte] By [saracgia] at [2007-11-26 17:28:22] 
A very general question?What is the ideal length (no of lines) of a java file? I know there are no hard core rules. I Just trying to improve my coding style and techniques.thks.
157

I would rather take it as 517? instead of 157..Expecting some genuine answers

@Op. Why do you think that there is an ideal length?What should you do if a class only is 40 lines? Add dummy code so that you will reach the ideal length?Kaj

You need to keep an eye out for the "weight" of your objects, and bigger (read more code) objects do tend to be heavier. But this really isn't a prime design consideration.... it's more of "refactoring for performance once it works" type consideration.
It's not exactly rocket surgery.

Maybe someone can read my ques regarding the debug mode and give some answers ?
Just tellin whatever I know abt the standards boss

nonsense, these days. that's a throwback to when everyone was compiling on terminals, where 80 chars was the width of the terminal screen. we had that mandated in our coding standards where I used to work. first time I did a compile-onsite, I found out why. but it's irrelevant now`
and nothing to do with the length of a class or file, either :-)

It's not totally irrelevant. (Ok, it's not relevant at all to the topic of the thread)
Line lengths of 80 characters reduces scrolling and makes it possible to print on paper (but who cares about that?)

Tats a cool piece of info .. Thanx...
(C hw easily I'm getting corrected now Mr. George :-) )
So about the debug question.... Some one pls..... i'm breaking my head over it

Acually a java class is a ideal class that not depends on the no of line in it....it should be well structured..containing re-usuable codes and clear seperation logical block in a method to do the specific task as like that if u want to do a specific task call the method...and method structure shuold not be so hezy and should't contain large no of lines...better to break each functionality to a perticular method...that will enhance the re-useability

Let each class represent one concept only and be functionally complete. Then you'll find that you automatically get a log-lin distribution. A few classes will be long and many will be short and the rest will be in between.

You had 37 then you change it 27.What difference does it make?

She knows that she will be forced to negotiate, and she wants to close the deal on 42 so she can't start with 37.

Though I'd make sure they was cooked all the way through, cant be too careflu.

In my shop you get dirty looks if the code is not readable because it wraps (unix) or needs scrolling (Win).

I'm fortunate enough to work in a shop that has moved beyond the 1980s. Our standard line width is 120, and there are certain cases where we're allowed to ignore that.

Get all the .jar files you can and add their lengths; then divide by the number of jar files - that's your average length. Now google for a length_stabilizer program that will grow or shrink your current .jar file to that average length. the shrinking is done using the new Xlintle pos-crash encode packing unicode algorithm originally developed by Naza for the Cobol enterprise space satalite super-subterfuge survalence rocketry network back in the 1970s.

right. we've tackled ideal length, had a crack at ideal width, can we now take the logical step and discuss the ideal depth? then on to duration :-)

I found an example of this pos-crash encode length_stabilizer last week, but found that the stabilization algorithm fails to counteract ill effects from the Heisenberg principle. I believe the accepted method for isolating this problem is to jump up the API ladder by two levels and do your own unicode packing.

Yeah, except the schools were closed yesterday (used a snow day) becuase they did not want the kids standing at the bus stops when it was (about -15 F). A lot of parents had to spend a sick day to stay at home with the kids (me included.)
When I was a kid, we'd pour rubbing alcohol on our bodies and walk to to school nekkid when it was that cold. But you tell the young people that, and they don't believe you.

We had to walk uphill for 10 miles at 5 AM - which meant getting up at 3AM to cut the wood and split it, bring it in, make a fire, so that mom could bake bread and cook breakfast - carry 50 punds of books on our backs through 3 feet of snow, then when we got to school we had to cut more wood and make another fire just to keep from freezing while we was taught.

When I was a youngster we didn't have any rubbing alcohol and no
clothes either. We'd set each other on fire to get some warmth, but
we didn't complain, we were happy in those days.

You were lucky then, we used to puke over each other during our 29000
kilometres run to primary school. That is to say, if there were anything
at all to puke because all we got for dinner was a bit of cold, black gravel
once a week. But we were lucky then ...

I would like to take this opportunity to remind you that if you keep signing your posts you'll have to use that installation utility I suggested.
People feeble-minded enought to sign everything regardless of whether it's necessary or not just cannot be trusted.

It's an interesting topic.
Should you learn Java before C++ or the other way around?
Although Java is rooted in C++, is Java such a different language that there's no comparision with C++ anymore?

Nah, I am sooooo sure not ... probably had to go up the volcano every coupla days to get the logs burning and then rolled them back down the hill (had to carry them up on their backs, no doubt!) while they were still burning. If they went out by the time they reached the bottom they probably just used their feet to light up the fire since I can't imagine that they had shoes.
Well anyways that's about what we did.
