java - JTextArea ran out of room? How much text can fit, can I fit more than that? -

-

i working on visualizer pattern found in prime numbers. here link maths stackmath:patterns in primes , full code stackcodereview:optimization of code

my problem seems running out of room in jtextarea.

errors: 

exception in thread "main" java.lang.outofmemoryerror: java heap space  @ javax.swing.text.gapcontent.allocatearray(unknown source)  @ javax.swing.text.gapvector.resize(unknown source)  @ javax.swing.text.gapvector.shiftend(unknown source)  @ javax.swing.text.gapcontent.shiftend(unknown source)  @ javax.swing.text.gapvector.open(unknown source)  @ javax.swing.text.gapvector.replace(unknown source)  @ javax.swing.text.gapcontent.insertstring(unknown source)  @ javax.swing.text.abstractdocument.handleinsertstring(unknown source)  @ javax.swing.text.abstractdocument.insertstring(unknown source)  @ javax.swing.text.plaindocument.insertstring(unknown source)  @ javax.swing.jtextarea.append(unknown source)  @ primesandbox.main(primesandbox.java:67)

line 67:

 screen.append(arrays.tostring(primesll.toarray()) + "\n");

so thing can figure have text in textarea. can increase size can hold? or must create method save of not shown text string , rewrite when scroll? (i don't want to)

the quick , dirty answer give more heap space:

java -xmx2g primesandbox ← gives 2gb, example

whether long term solution depends on whether need "little bit more", or whether have rampant memory problem.

you won't achieve memory savings moving strings around within application. string displayed in jtextarea not going more memory intensive string in field in class. writing out disk other option.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2

i need place custom knob image shadow uislider. far have image of 38x38, of there region defines shadow of knob. now while using image, when slide knob extreme ends actual knob not able cover end points, hence end points visible under transparent region of knob image this code using customize uislider uiimage *slidebtimg = [uiimage imagenamed:sliderknobimg]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatenormal]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatehighlighted]; how can implement custom knob shadow beneath it, covering end points?? look inside uislider.h , there methods let customize slider knob , track needed.
