Java arrays also have a .length property, so you dont have to pass another variable around with them to track their length.


Aside from that, they are very similar. Indexing is the same as C++ (0-based, using []), allocation is always done with new (like any other non-primitive type in Java), and they dont have to be deleted (again, like objects in Java).

int multi[][] = new int[10][10];

this deals with mulitdimensional arrays, basically creates a table 10 columns by 10 rows

got stuck here


file #1:
[php]
import javax.swing.JFrame;

public class lettercount
{
public static void main(String args[])
{
DrawPanel panel=new DrawPanel();

JFrame app=new JFrame();


char[] letterArray=new char[26];
int[] letterCount=new int[26];
int count=0;

for(int i=97;i<=122;i++)
{
letterArray[count]=(char)i;
//System.out.printf("%d = %s\n",count,letterArray[count]);
count++;
}

app.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
app.add(panel);
app.setSize(450,250);
app.setVisible(true);

}
}
[/php]

file #2:
[php]
import javax.swing.JPanel;

public class DrawPanel extends JPanel
{

}
[/php]

cannot find quality documentation on compents(Buttons, TextBoxes and other fields) or file manipulation.

[PHP]
import javax.swing.*;
public class LetterCount

public class lettercount
{
public static void main(String args[])
{
DrawPanel panel=new DrawPanel();
JButton button1 = new JButton("TextOnButton");
JTextArea area = new JTextArea();
JTextField textfield = new JTextField (numberOfcharacterLength);
}
}
[/PHP]

like that?

Yes That Is A Good Java Program. If You Are Beginer You Can Not Realy Undestand The Consep Of The Program

explain Andy... what do you mean i cannot understand the concept of the program.. i started java literally days ago... and i have been programming for some years.. just within the last year im heavily devoting time to it.

@reggaeton_king: that is declaring them correct?!?
do i add them to the panel using.. .add(TextArea/Button)?
And finally how do i gain control of the components? Such as
Button1_Click?

grrr .add(JButton) works... but it is added as the size of the entire panel! I cannot find a property or method to alter this in any way and it is highly annoying!!!

Does any know about any good documentation on file i/o???

or on componets and all of there basic properties(height,width,caption,location)...along with gaining control of them.(mouse down[on click], mouse up, mouse move)

I'd recommend looking up LayoutManagers from the Java API, especially the FlowLayout, GridLayout, and BorderLayout classes. The GridBagLayout class is another one you can look at, but it's a lot more difficult to get the hang of.

For file I/O, look at the Scanner class (especially with a File argument to the constructor).

For mouse/keyboard events, look at the MouseAdapter class or MouseListener and MouseMotionListener (which are combined into the MouseInputListener, but then you have to write your own function stubs for everything), and KeyListener
