java - removeMouseListener method not working -

-

the removemouselistener not working: if click on old jlabel still adding variable score. every time time lapse passed old object should have mouselistener removed , new 1 should 1 it.

timer pictimer = new timer(1000, new actionlistener(){              int oldrr=0;             int oldrc=0 ;             final int[] score = {0};             @override             public void actionperformed(actionevent e) {                 mouseadapter act = new mouseadapter(){                      @override public void mouseclicked(mouseevent e){                          score[0]++;                         lbltimer.settext(string.valueof(score[0]));                        }                     };                 arraywm[oldrr][oldrc].removemouselistener(act);                 arraywm[oldrr][oldrc].seticon(null);                 random random = new random();                 arraywm[oldrr][oldrc].seticon(null);                 int rr = random.nextint(3 - 0 + 1) + 0;                 int rc = random.nextint(3 - 0 + 1) + 0;                 oldrr = rr;                 oldrc = rc;                 arraywm[rr][rc].seticon(new imageicon("img/one.jpg"));                   arraywm[rr][rc].addmouselistener(act );             }         });

each time timer triggered, create instance of mouseadapter , attempt remove instance jlabel, label not have instance registered it. add instance of mouselistener label, compounding number of mouselisteners registered 1 label @ time.

instead, create single instance of mouseadapter , re-use, maybe this...

timer pictimer = new timer(1000, new actionlistener() {      int oldrr = 0;     int oldrc = 0;     final int[] score = {0};     mouseadapter act = new mouseadapter() {          @override         public void mouseclicked(mouseevent e) {              score[0]++;             lbltimer.settext(string.valueof(score[0]));          }     };      @override     public void actionperformed(actionevent e) {         arraywm[oldrr][oldrc].removemouselistener(act);         arraywm[oldrr][oldrc].seticon(null);         random random = new random();         arraywm[oldrr][oldrc].seticon(null);         int rr = random.nextint(3 - 0 + 1) + 0;         int rc = random.nextint(3 - 0 + 1) + 0;         oldrr = rr;         oldrc = rc;         arraywm[rr][rc].seticon(new imageicon("img/one.jpg"));          arraywm[rr][rc].addmouselistener(act);     } });

java - Static nested class instance -

-
this question has answer here: java inner class , static nested class 23 answers i came across in java, know static nested class why create instance of 'static'. isn't whole idea of 'static' use without instance? understand concept of inner classes, why (and frankly how possible to) create 'instance' of 'static' member @ ? why this: 1- outerclass.staticnestedclass nestedobject = new outerclass.staticnestedclass(); 2- nestedobject.anestedclassmethod(); and not this: 1- outerclass outerinstance=new outerclass(); 2- outerinstance.staticnestedclass.anestedclassmethod(); use on inner classes, keyword static indicates can access inner class without instance of outer class. for example: public class outer { public static class inner { /* code here. */ } } with construction, can create instance of inn

JavaScript - Replace variable from string in all occurrences -

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
