If you post your files, people will be more willing to help because it gives them time to look at your logic and help you understand which steps to take to complete your project.

Unfortunately, the implementation of ArrayList<T> looks [something] like this--


//... necessary imports

public class ArrayList<T> extends List<T> implements Collection<T>, Serializable{

...

You'll probably have to reposition your read-stream cursor after each object read, otherwise you won't retrieve the right byte value from the file to match the data type(s) for the Object you are...

Chances are likely that your Instructor wishes for both your getArms and getLegs methods to return an array of Limbs--



Arm[] getArms(){


return arms;
}

If you work in an environment similar to mine, you'll have people telling you to "GIYF!" quite a bit XD.

If there is a term you don't understand, you should definitely study it. I find it much...

Reflection is a very specialized solution, much like the Java Native Interface, Remote-Method Invocation, Wildcards, Design Patterns, transient values, volatile values, concurrency, etc.

Don't...

Use either TreeMap (http://java.sun.com/javase/6/docs/api/java/util/TreeMap.html) or HashMap (http://java.sun.com/javase/6/docs/api/java/util/HashMap.html)

Dictionary is also an okay way to go,...

public static void main(String... args){

Yes, I am very sorry for mixing static fields and members. Fields execute once and only once when the first object of the type is created (otherwise if a program executed all static fields of all...

static values are resolved at compile time, before objects are created.

A static member of a class is a shared location in memory between objects of that class.

Because static values are...

It may be possible that Java won't support an image-type in future releases and therefore not provide Serialization support for it but that depends on what it is.

I remember getting warning...

I don't believe Menus or certain 'Views' would be possible without some type of Composite structure, so a reference to a Collection (or more appropriately, a Composite) within a Collection is good...

Ok, let me see if I understand what you're asking.

Let's first determine what a collection is.

Collection (programming) - a structure that holds many objects of some type (in old versions of...

This managed to work for me--


import java.util.*;

public class TestClass1{
static String seatLayout = null;
static String fn = null;

public static void main(String... args){

You could use a State Machine, or State Pattern based on how many times an object has been encountered, or the State of an object can depend on the type of object it encounters...

It may simplify...

Would an Adapter be overkill?

I.E.




public class AdaptedA<T extends A> extends A{

private T myType = null;

Bah, disregard this post >_<



public <T extends A> void doSomething(T type){

if(type instanceof [SpecialNeedClass]){
// typecast only for this type
}
//...

This might help--


public class NullTest{

public static void main(String... args){

Object obj = null;
System.out.println(determineNull(obj));
obj = new Object();

I marked the Thread daemon as a good practice. Unfortunately it makes the example hard to see, the way the code is currently written. Consider this example instead--


import javax.swing.*;

Though Stephen has already pointed this out, you need to get rid of the access modifiers when declaring data types in your main method.

The reason is because it is irrelevant for a method to have...

Why exactly does class B have to extend A?

From an immediate glance I can see a potential cycle instantiation issue.

Think about it--

1) Class A, after static initialization, will...

Because I don't like to repeat myself (http://www.daniweb.com/forums/thread142503.html) =P

Sometimes the best way to test to see if something is concurrent or not is to use a tracing technique.

Basically split the code that is shared by threads onto different pieces of paper and pretend...

Here's yet another example, though probably overkill--


import java.util.concurrent.*;
import java.net.*;

public class ConcurrentExample{

public final ExecutorService es;
private Future...

I don't think it's the run method that isn't executing, Peter.

I think the problem is that you are not submitting a Runnable target as the argument for the Thread to execute.

I actually don't...

Maybe this will do the trick?

After running some tests I realized that somehow your transform is jumping between 1-22 on the (result?) matrice--

From what I understand, all objects are saved as .dat files for Java to reinterpret back into an object during deserialization.

To save files with an extension, I'd assume you'd use...

Yes, this version is much easier to understand.

Also the DataInputFilterStream is flawed and will only work for the InputStream provided by the System class, and does not work well with files.
...

This approach was probably unnecessary, but I took it anyways.

Try this--


import java.io.*;

public class DataInputFilterStream extends FilterInputStream{

public...

Personally I'd read all of the characters into a String then tokenize the String based on the space character.

The problem is that your Charact method is stuck in the while loop. You obtain the length of the file and state the conditon numChar != -1.

Keep in mind what data types are for. They store a copy...

Errors 1, 2 (and most likely 3) are generated because third.getPages is being parsed as a variable that exists within the Class associated by the object third.

There are a lot of questions...

First, will resizing the screen be an issue at all? If not then you could make a custom track using GeneralPath and Graphics2D fairly easily.

You could do so...

Why not g.fillOval()?

Also, will repainting be an issue? How much detail will be displayed on your screen? Are you at all using images?

A lot of questions come to mind since this seems like an...

Do you want to draw an image from a file, or do you want to be able to "rotate" a set of pixels such that they emulate a rotating String?

This can be either really simple or hard depending on...

I suppose you're using a GCanvas, or most likely the GraphicsProgram from the acm.program package?

You could have GCanvases pre-painted with components and when you advance a level, simply set the...

Although I haven't attempted it before, I'd assume you'd have a particular zone renderred on the screen with a type of "cover" over it. Either that or only render certain pixels ahead of the borders...

Javascript is in the web development section, not here =/

I didn't pay close attention to the first post. Apparently JFrame has an initial Layout of BorderLayout.

The OP added the TextArea to the Center Border. By simply adding the JMenuBar, I suppose it...
