got it... System.arraycopy

i basically have a long array i want to copy to another array object. does this copy by refrence? i know java doesnt do refrences but i read somewhere it would pass by refrence.


char[][][]...

thanks for the advice on object but it does function how i want it to. in each category object i have its name, and min/max values. basically i will be adding a category to an arrayList. then i will...

Hey, so this is killing me, I have a class category, and the equals looks like this:

public boolean equals(String s){
return s.equals(name);
}

this is because i have an arrayList of...

Also do all of the sub classes have the same methods? because if you define it as a doctor and dont have something like isJanitor() then it will give you an error.

Try testing it without using the employee class. does it still give you that error?

Your child class should extend object... unless employee does? try doing that... the odd thing is that technically everything is an object right?

hmm..
can you show me part of your code? say one of the classes and how your initializing the object.

in your child classes did you extend object?

Hey, Im having a problem getting my applet to repaint after it is resized. + and - buttons resize it but sometimes it wont get bigger or repaint.
here is the src for the applet

private...

what do you mean by the first one and the second one?

try this

public class Sort{
public static void main(String [] args){
int[]A={3,7,8,1,4,9,10};
A=sort(A);
for(int i=0;i<A.length;i++){
...

you should probabally stick within your comfort zone

this can be done in jsp

beter get started, come back when you have a problem and you've at least tried

no it wouldnt matter, it only matters if you define the same variable twice inside of a method.

how would you access them without class names? can you give me an example?

you too :-)

You can do Double.parseDouble instead of Integer.parseInt

hmm,
There is no clean way i can think of, but you can do

try{
int num=Integer.parseInt(firstDenominator.getText());
//if it gets to here its valid
}catch(NumberFormatException e){
//invalid...

basically you need to check if they have a value. if the enter nothing then the string will be null or "". If you try to set a integer equal to null, you will get an exception, so you need to check...

didnt microsoft already bootleg it? like they killed c++ with c# (Which sucks) And then the made like j++ and got sued over it or something. is there any chance (no) that j++ could take over java?

check out http://java.sun.com/j2se/1.4.2/docs/api/java/net/HttpURLConnection.html

hopefully you at least get javadoc

im not 100% sure on this but i think when you extend jframe, the method used to init the window is called initComponents. So when you override that it is called automatically. On line 54 it is the...

please use code tags :-)


public class MyNew extends JFrame implements ActionListener

public static void main(String[] args)
{
publicMyNew start= newMyNew();

can you make those photos larger?

As far as i know getText doesnt have any parameters. you would just say

String x=box.getText();
Long l= Long.parseLong(s);

textbox.setText(long.toString());

Its used in jsp, you may want to ask this in the jsp forum, and there are some helpful hints on google

Thats kinda harsh...
I got fine using netbeans when i first learned, it will show you errors and possible corrections. If you already know how to use notpad and cmd prompt then it cant hurt. In fact...

use a link (a href=bla)

I think your problem is your not making the thread do the typing, so look into making a new thread and making it write to the textbox then sleep.. Im not 100% sure how to though.

So... you've got a few problems with your code... one really really bad thing is that you make each method throw an exception. that means you will never see if there are any errors. You were getting...
