Well if you don't mix gui stuff with non-gui stuff, then you will have to change only a small part of your application.
Java applications use Swing and Android has its own components that do similar...

Solved. Please delete post.

Learn how to use loops.
Also note that
1 + 1/2 + 1/3 + 1/4 + .... = 1/1 + 1/2 + 1/3 + ... = sum(1/i, for i = 1 to n)
Your mission is to write the last expression in for loops which should be...

Problem with casting.

(int) Math.random() * 6
should be
(int) (Math.random() * 6)

Similar correction for the other one.
What happened in your case was that random() which is between 0.0 and...

First of all you should not create new board every time you make a move. That is a total waste of space and time.
Instead have methods to make and unmake a move. Also you need an evaluation...

Right. I still miss that const and final are not really the same thing.


Initialization do not have to be expensive. Initialization of local objects to null is a good solution.
A similar...

Actully it is better to initialize every time. The java compiler is weak in detecting all paths unless you make it so obvious

public class Test {
public static final int get() {
return 0;
}...

Local variables should always be initialized.


double af = 0.

As sean4u pointed out hashmap uses hash tables i.e (key,value) pair, so it is not sorted in any way. Interestingly it seems it is non-deterministic as well (you get different sequence every time you...

Yes proper back propagation is required for more complex goals. The OP's problem is very simple as to not require advanced solutions. He can even use a longjump once he encounters a goal at a leaf...

You are right. Oracle just points out use of inner classes is inefficient but is a good OO design. But does not recommend
any of the methods

General Information about Writing Event Listeners (The...

You have isGoalState inside the for loop as well so make the same change.


// recursively expands search space
output = recursiveExpandNode( current );
if( problem.isGoalState(...

Oracle suggests use of inner classes for listeners. Switch statements are not good OOP design .
On the downside, you will start having tons of .class files for each event handler. That could ,for...

Did you try my suggestion ? It is pretty straight forward and I can not see why it will not work.
Declare a member variable goalFound.

Boolean goalFound;

Set it to false initially (in...

I had similar problem that I solved using filters. LookupOp (Java 2 Platform SE v1.4.2)
This is much faster than the pixel by pixel method you are using. I have a white image with transperent...

To get results quickly,each animal's time series can be processed separately because the magical strength of
animals is independent of one other. This parallelization is limited by the number of...

I think your termination criteria is wrong. You should unwind the recursion when a goal is found anywhere in the tree (not just when the current node is a goal). A simple solution is to have a...

No the values of the variables should all be zero. You are directly printing out what is returned from the functions
without assigning it to your variables. So what you probably saw is those...

Here is an explanation for both of your questions: oop - Uninitialized variables and members in Java - Stack Overflow
The compiler forces you to initialize local variables partly because it can not...

Your problem is you do not assign the values returned from the function into the variables you declared.
Java passes primitives such as integers by value so you should not expect...

You did everything right except you forgot to return when the user enters a negative number.
You can handle exceptional cases by throwing an exception. But for your simple example, you can just ...

Sent you a PM.

I mean something like


for(int i = 0;i < 2;i++)
for(int j = 0;j < 3;j++)
for(int k = 0;k < 4;k++)
System.out.println(x[i][j][k])

Personally I find this simpler than the...

No thank you. Again what exactly did you find wrong with my _other_ posts ??

Then let it go. Hint I have reversi programs that 99% humans could not beat.

Unbelievable how I spend my time is...

Kevinworkman, lighten up really! What exactly did you find spoon feeding here ? (a) OP did a lot of work by himself b) I gave him a pseudo code that would definitely _not_ work. Just demonstrates...
