String with a capital S. It's the name of a class - they always begin with a capital. Seems very unlikely that the compiler would change the capitalisation on its own! Duplicate file versions...

I haven't gone thru all your code, but that looks sensible.
ps You don't need the toString() in a print - the print method calls it automatically. YOu can just say
System.out.println( games.get(i));

1. char is a numeric type, not some kind of String, so you don't (can't) use .equals(). You can just compare them as numerics (char1 == char2).
2. Wrong. 'A' and 'a' are different chars and are...

Hi. That other way of doing it is OK too. In my opinion the switch version is easier to understand and maintain, but other people may disagree.
It's not working because in the if statement on line...

MxDev: I guess English isn't your first language? The verb "demand" is the wrong word to use in this situation, and appears to be very rude. Eg, a master would "demand" something from his servant. ...

You're very close. Problem is that you parse the input to get an int value 1,2,3 but in the switch you look for values '1', '2', '3'. These values are type char, not int, and are the Unicode/ASCII...

Put a quick print statement at the start of your dealHand method so you can see if it's the listener call that's failing or the dealHand method itself. I haven't checked all the brackets and...

addKeyListener is only implemented for user interface components, so sooner or later you will need to use a JFrame or whatever. How is your pacman displayed?

I think well-formed just means it is correct in its syntax etc.

Yes, it is a standard problem. The solutions is called a "lock". Each thread has to get a lock on the object before it modifies it, then releases the lock when its finished. If a thread has already...

No, the two statements are equivalent for both boolean values.
(This is a little obsession of mine. I guess I see
if (booleanExpression == true)
once a week or so, and it always makes me wince).

These two statements create two constants TRUE and FALSE (Java constants are captialised by convention). These constants are members of the Boolean class, with values true and false respectively....

pps:
Rather than absolute paths that may not work from one machine to another, you can also get the paths to useful folders in a system-independent way with calls like...

Make the file name the complete path, startiung with c: or whatever.

ps: Don't forget that \ is the escape character in Java Strings - so to put a \ in the file path you need to code \\

No. A default constructor just calls the superclasses' no-args constructor. If you want to do any special initialisation you need to write a constructor (which may or may not take arguments)

The "break" on line 16 is outside any catch, so it terminates the list of catches associated with the previous try. So the catch on line 18 hasn't got a try to match to.

Not exactly. Constructors can have arguments, or no arguments. If you do not create any constructors, the compiler gives you a "default" constructor which is a no-args constructor that simply calls...

API doc states:

Where are the declarations of dob and telnumber (the instance variables, not the parameters)?

All you are doing here is changing a String within your program. Where does this connect with the actual filesystem?

It's annoying, but you can't use a primitive type (int/char/boolean etc) with generics.

Are you sure its "example" not "Example". Java is case-sensitive, and the convention is that class names always begin with a capital letter, so "example" would be a bad example for a class name.

Maybe you declared, but didn't initialise, your new textfield variables - you need something like

JTextField txtfNum1 = new JTextField ();

Reading it a agin with my glasses on, you seem to want to use txtfNum1,txtfNum2,lblAnswer as fields on your form, so maybe you should declare them as JTextField

str txtfNum1,txtfNum2,lblAnswer;

did you mean String ?

quuba's suggestion is OK, it will work, but it ties the external representation of the button text to the internal functions of the code, which is not ideal as a programming technique. (What happens...

In that case the new element must belong on the end of the list (ie sorts after every existing entry)

I made no assumption about the data, I was just exploring the logical consequences of the problem statement.
In the case you give, the boolean is false, no further processing is required. You will...

Did anyone say it was?

Is this a trick question? If array[i] > array[i-1] for all i, then surely array[i] > array[i-k] for all positive values of k. So you can ignore the inner loop. Or am I missig something?

Whenever you add an element, iterate thru the existing list elements until you find the right place to insert the new element. That way the list will always be in sorted order

Maybe the use of <E> in the iterator class is taken as a new declaration of a type, and masks the <E> that is declared for the outer class? If so, maybe you could declare the iterator class as
...

You use your comparator when you try to sort the array, for example

Arrays.sort(myArrayOfBankCustomers, new NameComparator());

However, you haven't implemented the Comparator interface...

Assuming these are your classes (not just ones in the Java API) put them all in a jar. Netbeans has a tool for creating one.

Move the declaration of au outside the action performed method, because now it exists only within that method.

Are you sure?


1. If the second compile always fails you cannot have a second .class file to put into the directory.
2. Thay already had that. What did you change?
3. This is wrong - the...

FYI:
"Boolean.TRUE" is valid Java, but "true" is also valid, and what most people would write.
This code also makes the very common mistake of redundantly using an if test to set a boolean. ...

It's the .class files that need to be in the Assignments dir; the source .java files' locations are irrelevant to this.
The classpath must point to the folder that contains the Assignments folder,...
