java - JTextArea consumes a lot of memory -

-

i having memory issue java , swing. have jtextarea (same issue jtextpane) use redirect stdout c++ executable. , because i'm outputting lot of stdout, jtextpane consuming lot of space. in case, boiled down following code, in java. 

private javax.swing.jtextarea jtextareastdout; ....  (int = 0; < 200000; i++) {     string randomstr = uuid.randomuuid().tostring();      jtextareastdout.settext(randomstr);  //<tag_memory>     if (i % 100 == 0)         system.gc(); //<tag_no_help> }

the above code consumes 100mb. tag_memory line commented out, lot less (30mb other code & ui). how can reduce java's memory usage? using java 7 update 4.

thanks in advance.

i don't understand memory going.

plaindocument tells story: either 1 or 2 16-bit code units per code point, map of line starts , impedimenta needed make editable. read-only viewing, i'd use redirection: yourprogram 2>&1 > view. in java, read stdin list<string>, 1 string per line, , view jtable. default renderer quite efficient. there's related example here.

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
