The Toolkit class provides you with a method [inlinecode]createCustomCursor(Image cursor, Point hotspot, String name)[/inlinecode]. [inlinecode]cursor[/inlinecode] is the Image of the cursor, [inlinecode]hotspot[/inlinecode] is point from the top left corner of the Image where the actual click of the cursor is, and [inlinecode]name[/inlinecode] is just the name of the cursor. Anyway, …

You'd compare an object to [icode]null[/icode] with [icode]==[/icode]. I think you want one of the following. It's hard to determine the exact behavior you're looking for from your code. [code=Java]if (child == null) child = new Lista(c, null); // Or: if (child.getData() == null) child = new Lista(c, null);[/code]

Do you have a firewall that's getting in the way?

Yes, you need an internet connection...

Use [icode]==[/icode] to compare values; [icode]=[/icode] performs [i]assignment[/i], not comparison.

Java doesn't support creating variable names dynamically.

Applets shouldn't have constructors because an applet isn't guaranteed to have a full environment until [icode]init[/icode] is called. So the code you would normally put in your constructor should go into the [icode]init()[/icode] method. Also, things such as width and height of an are automagically pulled from the HTML for …

[QUOTE=dickersonka;732548]masijade is correct, i think its more of a convention to follow though[/QUOTE] It's not just a convention, it's a good programming practice. If you incorrectly attempt to override a superclass's method without the annotation, your error will be [i]silently ignored[/i]. If you do include it, you will get a …

I'll go through each of the errors I see. 1) [icode]new int[5] //Constructing the array[/icode] This line does nothing useful and is missing a semicolon. You should remove the line completely. 2) [icode]int[0] = input.nextInt[/icode] This line should be using the variable name, not the variable type to reference the …

Objects are destroyed for you by the garbage collector.

[QUOTE=stultuske;729819]I take it getRadius is a method, so call it like a method, not like some static variable[/QUOTE] You mean public variable.

Keep in mind you aren't looping here, so the sum variable is not doing anything useful. You can rewrite javaAddict's code to be like this: [code=Java]public static int myMethod(int counter) { if (counter == 0) return 0; else return counter + myMethod(counter - 1); }[/code]

You have all the right logic, you're just missing half a line. Looks like a silly mistake on your part. [code]char c = word.charAt(0); [b]reverseWord += [/b]reverse(word.substring(1)); reverseWord += c;[/code]

A superclass must always be constructed before its children. There are two things that are implicit in your MainClass class. 1) Since you did not specify any constructors, you have an implicit default constructor: [code=Java]public MainClass() { }[/code] 2) Since you did not specify which constructor for your superclass to …

You have to compare each one explicitly. [code=Java]boolean invalidColor = (FColour != 'B' && FColour != 'L' && FColour != 'W' && FColour != 'R' && FColour != 'Y' && FColour != 'G');[/code]

Every class has a [icode]hashCode[/icode] method. Just don't use the URL class for this because it's broken. use the URI class.

The [icode]java.util.Stack[/icode] class is a legacy class. You should use the [icode]java.util.Deque[/icode] interface instead, which supports LIFO.

Is this just a syntax question? Because your psuedocode is (nearly) correct. [code=Java]// MyObject is the class of the object you want to compare public boolean(MyObject obj1, MyObject obj2){ if (obj1.getSomeProperty() == obj2.getSomeProperty()) return true; else return false }[/code] Or, more simply: [code=Java]public boolean(MyObject obj1, MyObject obj2){ return obj1.getSomeProperty() == …

The [icode]Math[/icode] class is imported by default; you don't need to import it manually. masijade was suggesting that you [i]look in that class[/i] for a method that might be useful to you.

This is what files are for. Just store the data from the non-Java application into a file, and then read that data from your Java application.

What is with the poll?

How can [icode]hashCode[/icode] be returning [icode]null[/icode]? [icode]hashCode[/icode] returns an [icode]int[/icode]. Also, if you are using the [icode]URL[/icode] class, don't. Its [icode]equals[/icode] and [icode]hashCode[/icode] methods are broken. Use the [icode]URI[/icode] class instead.

What is the problem?

Can you post a [URL="http://mindprod.com/jgloss/sscce.html"]SSCCE[/URL] to demonstrate your problem?

Just wondering... why do you want to do this? The BigInteger class is immutable, so two instances sharing memory will never be a problem.

So you need to get input from a user and store it in a text file? By the way, ".txt" is the extension typically used for a text file.

You don't need to use a loop if you take advantage of the API. If you take the length of the array returned "scanning" for your substring with [inlinecode]String#scan[/inlinecode], you will have number of occurrences of that substring.
