if you do things like removeAll() on a JFrame or JPanel, then after adding new panels, you might need to call revalidate() or validate(). I've told people that before and they've reported back...

If you declare a method as taking an int as a parameter, then you need to pass that int. i.e. in your setX and setY methods, you cannot call setX(), you have to call setX(PUTANINTHERE!!!)

hope...

This is definitely interesting. Before I get into my crazy idea of how to do this (that involves bit stuffing and using a special character to denote the start and end of images) let me make sure I...

Why is there so much code in your remove method? All you need to do is search linearly through your array looking for an item with the name that matches the String you're searching for. That should...

Your error indicates that you attempted to parse an integer at line 128 of your program (which is correct: it says Integer.parseInt(input)). However, the program was unable to parse an int, because...

Did you even look at his code? The problem is obviously with the way he is reading in the text file.

@OP:

Scanner's next() method reads in input between the delimiter pattern, which by default...

SWT was created for faster native widgets - it is faster because it uses the OS's native tools to draw the widgets, essentially. However, Swing should be plenty fast for most any purposes, and I...

If you use Java's built in Stack class and Queue class, you can simply call the appropriate methods to add the items on and take them off. For both of them, to add an item on, you probably just use...

abccba

if you add each letter in order to the stack and the queue, here is the final stack and queue (in the order they would be popped off)

1. abccba

Check is extremely simple actually. If any piece can currently move to the king's position, then the king is in check. Since you already have to implement the ability to allow players to move any...

Like the docs say, split does not return the character that was split around. My point in my previous post was that you can easily figure out where the characters were anyway by using a little...

My example was pretty long, but try to grasp the concept and I think you'll be able to complete your program. Again, the basic idea I'm proposing is that you multi-thread your application so that the...

Sorry, took too long and couldn't edit my last post. Update:

Ok, so this seems to be the issue: since read() blocks while it waits for input, when the client's receive() method is executed, all...

I looked through your code, and I don't see a reason why you should be continuously adding and removing the mouse listener. If there is no reason to do so, don't do it. (I.e. it adds nothing to your...

Put "Website Major" in your resume, and I bet you never get a job. But seriously, the lack of social skills and self motivation is probably a good cue for where your future is going.


Why do you...

Re-read your project assignment. Pay particular attention to the part that I bolded.

Character ch = new Character('\u00C3');
char prim = ch.charValue();
System.out.println(prim);

Something I just learned how to do after a quick look up in the Character class documentation. I'm...

The reason it gives you trouble is because when the user enters an integer then hits enter, two things have just been entered - the integer and a "newline" which is \n. The method you are calling,...

I'll give you some hints and leave the rest of the work (such as using the definition of theta to come up with the values that prove it's big theta) up to you. But these are just my thoughts, no...

Not that the OP is interested, but in case anyone is, finding the minimum and then finding the maximum takes (n-1) comparisons each for a total of 2n-1 comparisons. The same can be done in about...

edit - sorry, posted this at the same time as James

int N1, N2, product, PoNoN1, PoNoN2;
PoNoN1=N1+"(POSITIVE)";
You can't store Strings into integers. So declare PoNoN2 as a String, not as an...

The point is, the existeValor method takes three arguments, but you were only passing in one argument. That will only result in a compiler error - the two are treated as completely different methods....

You can find all kinds of information on these on google. Top down is typically thought of as breaking your problem into subproblems, then breaking these subproblems into further subproblems until...

Incorrect. Anything in that first argument has to amount to a String, just like the javadoc says for the drawString method. So you could put "I'm a String!" + object.toString() in that slot if you...

It seems like you already figured out how to get the Characters from the ArrayList and compare them to see if they are the same. Now all you need to do is write a for loop that prints from 1 . . n...

Other things you should be aware of:

James is right - you can create the JLabels in the class definition, but nothing further. In the future, you should use an array if you have any type of collection of Objects like you do above. For...

WorkThread should not be running on the EDT. This indicates that WorkThread is not running in a separate thread - so the new Thread was not set up properly. Look up how to create a separate Thread on...

I'm not knocking adatapost's suggestion - he gives great suggestions - but his suggestion might be a little too advanced for what you're doing right now. Either way, you might want to explain exactly...

you didn't use code tags. read the stickies. all of them. completely.

JButton Reset = new JButton("Reset");
centerpanel2.add(new JButton("Reset"));

Should be:

centerpanel2.add(Reset);

Correct me if I'm wrong: What you are trying to do is compare the first column of file 1 to the first column of file 2. So let's say you put all of the Strings from column 1 of file 1 into an...
