Graphics#drawString only accepts a String value (there is also a varient that accepts AttributedCharacterIterator, but I'm pretty sure that's not what you're trying to use). Also, Graphics#drawString only takes three parameters, a String or AttributedCharacterIterator and two int values... You could use Double.toString or NumberFormat to convert the value to...

You could add a private List<oval> ovals; list to the class that contains the actionPerformed method, and add the ovals to that list (as it could like you're doing already). Then you create a public List<oval> getOvals() method, and use that to access the list from your draw method in...

Should I develop my app as an applet, No! See Why CS teachers should stop teaching Java applets for lots of reasons not to code applets. ..and then somehow modify the 'tasks.txt' file on webpage(and how can applets modify files on webpages)? The 'somehow' is with the help of...
You get the list's iterator before you change the state of the list, and then you use the iterator to iterate through, but now the iterator is no longer appropriate. Solution: change that order. Get the iterator only after adding items to the list, or use a ListIterator and add...
The applet should provide a method to confirm it loaded OK. A JS should poll the applet for a time, trying each time to access that method with an 'OK' result. It the JS has not received an 'OK' after a certain time limit, use the JS speed test.

There are some problems with above constructions. You do recursive move() method inside draw() method. But in Processing draw() is called many times in each second by animation thread.

You are extending the Applet class in your package.

The Component which has a registered KeyListener must have focus for the KeyListener to fire.

paint is called automatically by the painting system when it wants your component to be repainted.

Your MouseInsert is not an inner class for the Mousebandymas (by the way, why do you extend Mousebandymas?), so when you change toFill, you change some other toFill, not that one from Mousebandymas.

Applets are expected to run within an applet container, which is commonly supported by browsers (and the applet plugin). You can't run them from the command line, at least not without modifying the code to support a window based solution. Take a look at: Creating a GUI With JFC/Swing for...
java,exception-handling,applet,awt,thread-sleep
You should never call methods such as Thread.sleep on the event dispatch thread (i.e. in paint methods). This will render the whole GUI unresponsive.

I assume that you just want to practice how to write a applet. For development purpose, you can create a keystore and then use it to sign your applet.jar. Go: Start Menu > Execute > cmd.exe Input: cd / keytool -genkey -dname "cn=CN, ou=OU, o=O, l=L, st=ST, c=C" -alias mykey...

I eventually tracked down the cause of this. As indicated by @immibis's comments, the exception was during class initialization, rather during construction of an instance.

I think you have some conceptual misunderstandings reflected in your code here. It's important to consider which component you are adding the ActionListener onto.

Applets load images asynchronously, so it is likely the images are not fully loaded before the applet goes to paint.

I'm pretty sure this isn't possible because of Java's security system. The best way to so it is to have a master class, which has an array of JApplet. On that master applet I would create a method that sets the visible applet from the array, calls init() and when...
The real answer to your question is that you're thinking about it a bit sideways: you shouldn't be using an applet (they're dead), and you shouldn't try to do it all by yourself without any libraries.
