Moving to C++.

> Well its just a question
And I just attempted to explain. You didn't bother to answer my questions about the errors you received, so I can't really clarify why you received them.

Were you defining those at the class level or in a method? Static declarations like that only apply at the class level.

I'm guessing you got error 2 with statement C? C is not valid syntax.

Check spelling and capitalization as well.

Say you finish asking a question...

And what do you think that error means?

You'll find that "an error" is very little to work with. Post the entire error message.

The first is standard shortcut syntax for the creation and initialization of an array in the same statement it is declared.

The second is using a static code block to create and initialize.

Actually, you should override paintComponent(Graphics) instead of paint(Graphics) and called super(g). The paint() method has a few other responsibilities such as painting the border and children as well managing partial repaints.

Overriding paintComponent() is recommended for custom rendering.

Why not use Google instead of expecting others to do it for you?

If you wish to access the method without an instance of your WordRepeater class, you will need to declare the tester method 'static'.

public static boolean tester (...

You need to loop through the list and get each "Ticket" object and check its id. You can only call getId() on an object of type Ticket, not the Ticket class itself.

You don't need to set the background in paint(). You can set it in the constructor once and it will persist.

You specifically do not want to override the paint() method like that because you are preventing the labels from being rendered at all. In Swing components, you should override paintComponent() if you need to provide custom rendering.

Just remove the paint method declaration altogether and move your background call up to where you are adding the other components and see if that gets you where you want to be.

Yes, as Norm said, you do not need to create those arrays in the method call. I merely did that as a quick example in your other thread. That signature is actually

createCategoryDataset(java.lang.Comparable[] rowKeys, java.lang.Comparable[] columnKeys, double[][] data)

The arrays do not even necessarily have to be String[].

Actually, that is vegaseats signature.

Thanks. Dealt with.

Show some effort and ask specific questions about the part you are struggling with. Regardless of circumstance, this is not a homework completion service.

James is correct. Please start a new thread if you have a question and state it more clearly. What you posted is rather vague.

Thread closed.

What have you tried so far? What have you thought about trying?

If the rental company must display the cars that are available, it must have some access to tell if the car is currently rented.
I'm not sure what you are expected to do there because I don't know all the parameters and expectations of your assignment.

Perhaps you can check one of the other properties that you do have public access to? The data for a few of them looks like it will be easy to tell if the car is rented.

If you want to print out the index along with the description, you can use the following basic idea:
1) for() loop over the list, from 0 to size-1.
2) inside the loop, get() each car and check if not onloan
3) if not onLoan, print the index (which is your loop variable) + getDescription()

If you prefer to use the for-each loop you started with, consider the following:
1) if (cars.size()>0) isn't really needed because for-each loops automatically only loop through elements that are in the list. If it's empty, the loop just doesn't do anything.
2) This seems counterproductive to counting: int i = 0;

No, Java uses zero-based indexing almost exclusively. You can't change it to start at 1.

The fix I'm referring to is not difficult and is something you'll need to get used to in Java. In all places where you check if carNum is greater than size(), you simply need to amend the operator you're using. If the index equals size, that is also an invalid index.

That does not look like a valid connection string. You need to use something closer to this

String connectString = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=" + projectDirectory + filename;

"It is showing error" is not helpful to anyone. If you want help resolving an error, you need to post what it is.

You also need to read the forum rules about using clear, relevant titles for your threads. "problem!" is not a useful title.

Don't forget that index==size() is also too large. Double check your verification code with that in mind.

Yes, you can use this method to create any series and category labels you want

final CategoryDataset dataset = DatasetUtilities.createCategoryDataset(
            new String[]{"a","b","c"}, new String[]{"bob","mary","sue"}, data
        );

That produces data series a,b,c and the domain categories bob,mary,sue along the x-axis.

It's your dataset. You have created it with those values (category,value) .

I believe James is correct that the problem lies in the missing revalidate() and repaint() on your panel. When add/remove components from a container, you should validate the container so layout is updated. Repaint will ensure that whole component gets repainted and not just regions that the RepaintManager thinks are dirty.

In your rent and return methods, you're looping the whole list and acting on every car

for (Car car : cars) {...

You need to get() just the one car and operate only on that car object.

Your domain axis (x-axis) should display the categories you've supplied. It's not a range of values, it's a discrete set.

Why did I write this in bold?

Well, that's off-topic and more of a personal problem.

Perhaps a reply acknowledging the suggestions pyTony and woooee made above would be more appropriate.

Look over the APIs for those two classes. There are methods to print new lines.

BufferedWriter is another option.

Hotswap just refers to automatically applying changes to your current debug session without need to stop, compile and restart the session. From some quick reading, Eclipse is supposed to do this for you automatically if you save changes that you make while debugging a file. You'll need to be sure that 'Build automatically' is enabled in your project.

Hotswap does have some limits like not being able to make schema changes such as adding/removing properties or methods, etc.

You can use PrintWriter or FileWriter for that.

Why have you copied in a partial method declaration into your code block?

As far as where to check the string, you need to check each line, right? That should suggest where to put the code.

You only have to do two things:
1) Determine if the line read contains the string the user input.
2) If it does, return the portion of that string after the ":"

As Norm already said, you just need to read over the methods in the String class that do those things. The comparison methods you listed above compare an entire string. That is not what you are wanting to do.

I'm not seeing any reason to even have the ArrayList at all. You can add and remove nodes directly on the tree model.

You can mark a thread solved by clicking the "Mark This Thread As Solved" link at the bottom. Others can still post in the thread.

Only a moderator can actually close a thread.

I can read just fine kesh1000. The "engine" you use should have also noted that 'c' is not a legal statement. An int is not an object.

If you have to choose three, it's an invalid question. Only two of those are legal operations.

(And one of those two is only valid for testing object reference equality)

Perhaps change the parameters to your addModule() method to DefaultMutableTreeNodes or at least pass tree model you wish to add the node to?

It's really a TreeModel B that you want to add nodes to from TreeModel A. Specifically there is some node in B that you want to attach a new child node to from model A.

You can only add nodes to other nodes, which you do through the TreeModel. The JTree component does not have an add(Node) method.
