You can keep JPanels in memory and switch them when you want to.

Simply check if all chars are numbers?

Are you sure you need such monsters:
ArrayList<ArrayList<ArrayList<Double>>> all = new ArrayList<ArrayList<ArrayList<Double>>>(); ? :D

It would be much easier if you tell us what have to do your code and change that language (spanish?) to english ;)

1. You didn't gave us the whole code.
2. What seems to be the problem?

1. What seems to be a problem? Have you ever wrote computer program?
2. Have you tried to write anything? What was the reason that stopped you?
3. Do you expect the community to write program for...

The answer is: yes.

What about LinkedHashMap? ;)

You can also use Apache Lang library:
org.apache.commons.lang.StringUtils:
method join.
So:


StringUtils.join(array, "");

does the job.

You have to write as many bytes as possible and start analysing it.
Try to find some simple bytes sequences occurring when you "destroy the blocks" or whatever you do ;) Maybe you will find your...

So what's the problem, if you have already written it? :)

"newNPC(int,int,int,int,int,int,in
t,int,boolean) in icedice.Engine cannot be applied to (int,int,int,int,int,int,i
nt,int,boolean,int)
"
(int,int,int,int,int,int,int,int,boolean)...

read(byte[] b) : "Reads some number of bytes from the input stream and stores them into the buffer array b."
Some bytes != all bytes.
use read(byte[] b, int off, int len) , where off = 0 and len...

Aw snap.
Use if statements instead... :)


if(hours => 1 && hours < 13) print no better plan
else if(hours => 13 && hours < 27) print B
etc

Switch doesn't make any sense here.

Well, why not try specifying right paths?

Should be initialized to the head of your list, otherwise the code will throw NullPointerException.

You have to use floats or doubles instead. Integer doesn't provide you anything after decimal point.

Why not do something like that:


long elapsedtime;
Date starttime = new Date();

selectionSort(randomArray);

Date endtime = new Date();
elapsedtime = endtime.getTime()-...
