java - Timer implement error -

-

i have error timer, , don't know error situated in code.

error:

exception in thread "main" java.lang.error: unresolved compilation problems: constructor timer(int, player) undefined method start() undefined type timer

at player.(player.java:12)

at game.main(game.java:11)

import java.awt.graphics; import java.awt.graphics2d; import java.awt.event.actionevent; import java.awt.event.actionlistener; import java.awt.geom.ellipse2d; import java.util.timer;  import javax.swing.*;   public class player extends jpanel implements actionlistener{ timer t = new timer(5, this); // error (line 12) double x = 0; double velx = 2; double y = 0; double vely = 2;  public void paintcomponent(graphics g){     super.paintcomponent(g);     graphics2d g2 = (graphics2d) g;     ellipse2d circle = new ellipse2d.double(x,y,40,40);     g2.fill(circle);     t.start(); // error }  public void actionperformed(actionevent e){     x += velx;     y += vely;     repaint();   } }

you've imported java.util.timer. maybe meant javax.swing.timer?

you can google more info, here pretty explanation of difference between two.

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
