java - select a word from a section of string? -

-

i'm trying find out if there methods in java me achieve following.

i want pass method parameter below

"(hi|hello) name (bob|robert). today (good|great|wonderful) day."

i want method select 1 of words inside parenthesis separated '|' , return full string 1 of words randomly selected. java have methods or have code myself using character character checks in loops?

you can parse regexes.

the regex \(\w+(\|\w+)*\); in replacement split argument on '|' , return random word.

something like

import java.util.regex.*;  public final class replacer {    //atext: "(hi|hello) name (bob|robert). today (good|great|wonderful) day."   //returns: "hello name bob. today wonderful day."   public static string geteditedtext(string atext){     stringbuffer result = new stringbuffer();     matcher matcher = finitial_a.matcher(atext);     while ( matcher.find() ) {       matcher.appendreplacement(result, getreplacement(matcher));     }     matcher.appendtail(result);     return result.tostring();   }    private static final pattern finitial_a = pattern.compile(     "\\\((\\\w+(\\\|\w+)*)\\\)",     pattern.case_insensitive   );    //amatcher.group(1): "hi|hello"   //words: ["hi", "hello"]   //returns: "hello"   private static string getreplacement(matcher amatcher){     var words = amatcher.group(1).split('|');     var index = randomnumber(0, words.length);     return words[index];   }  }

(note code written illustrate idea , won't compile)

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...
