swing - Timer works with println but not label using java -

-

i have labels become visible when letter pressed.

private void formkeypressed(java.awt.event.keyevent evt) {                                     // todo add handling code here:     if(evt.getkeycode()==keyevent.vk_a){         jlabel7.setvisible(true);                     jlabel8.setvisible(true);         jlabel9.setvisible(true);         myblink();     }

i have label8 on timer myblink()

public void myblink()     {     new timer(1000, new actionlistener() {         public void actionperformed(actionevent e) {                                 system.out.println("begin");             jlabel8.setvisible(false);             jlabel8.setvisible(true);             system.out.println("timer");         }     }).start();     }

i have placed printlns see if timer begins , ends , when press key "a" output shows begin timer multiple times label not appear , disappear. tweak code need? missing? set of eyes.

this because call successively setvisible(false) , setvisible(true) done fast seen, should use variable , modify value time action of timer called next:

public void myblink() {     new timer(1000, new actionlistener() {         boolean visible = true;         public void actionperformed(actionevent e) {             jlabel8.setvisible(visible = !visible);         }     }).start(); }

this error has shown on many times, seems. prominent answer issue seems restkit 0.20 — coredata: error: failed call designated initializer on nsmanagedobject class however, solution posted doesn't work me. let's start beginning: i want upload file server. want parse response make sure uploaded. if not, try again later. model has boolean variable called nsnumber *senttoserver purpose (in coredata, bool saved nsnumber ) . because don't know whether sending going successful, save entity coredata model first before sending via restkit. when post request successful, server returns json string this: {"id":14,"created":true} notice that, of course, id not set on coredata model yet, both id , created new informations model. here's model: @interface recording : nsmanagedobject @property (nonatomic, retain) nsstring * audiofilepath; @property (nonatomic, retain) nsdate * createdat; @property (nonatomic, retain) nsstring * deviceid; @
