SSCCE of my graphical interface with memory leak

[Sal]

Hi all,
I tried to write a SSCCE of my graphical interface that has some
problem of memory leak.
I resolved the problem minimizing and maximizing the graphical
interface (f.setState( Frame.ICONIFIED ); f.setState( Frame.NORMAL )
but i don't understand where the memory leak are...

in the login windows you have to put:
user:guest
PW:guest

Thanks

Sal

Don't use these calls.

Don't use TABs in Usenet posts.

double impVmin =0; ....
JLabel labelVmin = null;

No need to initialize instance variables to zero or null; that's what happens
already.

String data_med_h = "";

It is often better to leave String instance variables at null rather than
initialize them to a throwaway value.

double Vmin = 30;
double Vmax= 10030;
double Smax =10030;

If these magic numbers are significant, you should make them static final
variables, i.e., compile-time constants (and therefore use all upper-case
variable names for them).

You also should use double literals to initialize double variables.

catch(Exception e) {}

Do not ignore exceptions. Log'em and handle'em.

UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());

Why did you do this more than once?

You have done everything in the constructor. Move all the real work out of
the constructor. It is dangerous to perform a whole lot of action inside an
incompletely-constructed object.

Refactor your two windows to be instantiated by separate classes, or at least
by separate methods.

Likewise with the different branches of "if ( ae.getSource()...)" blocks -
they belong in separate methods.

Make sure GUI actions happen on the EDT and that non-GUI actions don't.

See if you can make your SSCCE actually a *short* self-contained compilable
example.

[Andrew Thompson]

Hi all,
I tried to write a SSCCE of my graphical interface ..

Lew mentioned that was not an SSCCE. Since I was
really bored and worked with it anyway, I can flesh
that out.

It was not..
Short - at over 1300 lines.
Self Contained - it had unused imports for the
'javax.comm.SerialPort', and other imports
for 'com.toedter.calendar.*' and also used images
that I do not have locally*.
Compilable/Correct - Not compilable due to missing
imports, line wrap, and a few other things, not 'correct'
since the final version I got compiled and running
showed no memory leak, and therefore it was not an..
Example - of the problem.

So - apart from missing every single letter in that
abbreviation, what would make you think it was an
SSCCE?**

* Oh, BTW - besides the other dozen or so rotten or
rank things I observed in that code while fixing it
to the point where it would run, I noted it was
instantiating ImageIcons for JLabels directly within
the even handling sections of code.

Since the JVM can be very 'memory leaky' with images
generally, I recommend creating these images *once*,
first time needed, and keeping references to those
initial images for later use.

** Please, go back and read the document to which
Lew linked.

Ok "probably" it isn't a SSCCE
But it was my first attempt to write something Understandable...
Anyway you tell that there are not memory leak, but which Operating
System are you using?
Please try to delete this two lines
f.setState( Frame.ICONIFIED );
f.setState( Frame.NORMAL );

and tell me if you can see that the memory increase.

Thanks to all

You might also consider the refactoring suggested earlier, and especially
moving the work of the class(es) out of the constructor(s).

 

[Andrew Thompson]

No. No probable about it. That code is not an SSCCE*.

..Please try to delete this two lines ..

No. I am not inclined to provide more help until you can
provide an SSCCE. Once you've read the document on
the SSCCE, you will probably understand why.

* And this is coming from the person who coined the
abbreviation, and wrote the SSCCE document.

Oops! I probably should..
a) not have replied to a post of which I quoted nothing,
b) have got the attributions correct.

My bad.

Hi all,
I tried to write a SSCCE of my graphical interface that has some
problem of memory leak.
I resolved the problem minimizing and maximizing the graphical
interface (f.setState( Frame.ICONIFIED ); f.setState( Frame.NORMAL )
but i don't understand where the memory leak are...

in the login windows you have to put:
user:guest
PW:guest

Thanks

<Main Class CODE>

[snip not so S SCCE]
What was not short.

What makes you think there is a memory leak? Memory usage in a Java
application can go up and down. Don't worry about it unless you get
OOM exceptions.

As a side note, you have WAY too many fields in that class. They
should probably be broken out into their own classes, grouped by
logical association.

 

[Lew]

As a side note, you have WAY too many fields in that class. They
should probably be broken out into their own classes, grouped by

Another possible refactoring is to local variables. It may be that not all
those variables should be instance variables.

Instance variables have wider scope and generally point to longer-lived
objects than local variables (and do so for longer). Limiting scope and
lifetime tend to be a good thing.

This tip requires that you also refactor your logic into methods. "Local"
means "within methods".

A related tip is to declare variables as close as possible to their point of
use. (/Effective Java/, Joshua Bloch.)

Note that the 'sig. delimiter' is actually three characters '-- '.
(I noticed because my WITUN usually hides sigs. unless
the user wants to see them - but your sig. shows up
automatically.)
