No, you do not have 100,000 panels on top of each other. But if the screen is still being filled with black, you might want to insert the line:

That's alright. you can still make a tray icon, in Java 1.6, there is a SystemTray class that can add an icon to the tray, and you don't have to mess with JNI (YAY!)

If you're asking about how to bring UP a window or do something when a hotkey is pressed, it would involve making an invisible Window that's always on top of everything else, and adding a key...

If I'm understanding your question, you want to know how to pass ArrayLists as arguments to methods, right? It's the same as any other arg.

When you try to convert a String to an int, you have to be careful. If you don't put a value in, or type a letter by mistake, it can lead to strange results. Try defaulting the JOptionPane's value...

yes, but after the foo.doSomething() line, put a "}" to close the method.

also, you don't want another main method inside class foo, call it something else, and it probably doesn't need the...

you don't want to declare class foo inside your main method. close the method before coding the foo class

No problem, don't forget to set the thread to solved =)

O.o That's a lot a white space 0.0 In the future, try to write and post a simple example of what's wrong instead of posting your entire code.

What if when you resize the JFrame, you pass the JTabbedPane the width and height through the resize(int width, int height) method while resizing the JFrame?

you could check the number of characters in the string, break it up into sections using a String ArrayList, and insert a \n after each string portion

if you messed with it enough, the modulus would work... but... it's a hassle, and breaking the String apart using the Scanner class is easier, in my opinion. If you create a Scanner that reads the...
