java - Why is this string timer for delaying not working? -

so have string timer

import javax.swing.timer; import java.awt.event.*;  public class delay implements actionlistener {     public void delay(int time)     {         timer t = new timer(500, this);         t.start();     }     @override     public void actionperformed(actionevent e)     {     } } 

delays 500 ms (there no action performed), however, when call it

delay d = new delay();         for(char c : dialogue.tochararray()){             g2.drawstring(string.valueof(c),x,y);             d.delay(5000);                               //here delay             x += 10;             if (x > 90){                                                                                                x = 75;                                                                                                          y = y + 20;                                                                                         }         } 

there no delay between writing letters. why this? thank you!
