java help! cant access array, srry for size

[The Terk]

i have a problem with java: the problem is the user is prompted to insert the values of 10 integers and they are stored in an array, then an applet is used for the user to put in an index and show the value...

ok, i am havin a problem passing an array to this funcion, it seems like whenever i want to put in the location, and hit show, nothing is being displayed... which is odd... thanks, i will answer all questions towards this question
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.border.*;

public class ArrayDisplay extends JApplet implements ActionListener
{
private JTextField arrayValue, arrayElement;
private JButton jbtShow, jbtSave, jbtLoad;
private int array[];

public void init()
{
int array[] = getArray();
JPanel p1 = new JPanel();
p1.setLayout(new GridLayout(2,2));
p1.add(new JLabel("Array Index"));
p1.add(arrayValue = new JTextField(4));
p1.add(new JLabel("Array Element"));
p1.add(arrayElement = new JTextField(4));
arrayValue.setEditable(true);
arrayElement.setEditable(true);
p1.add(jbtShow = new JButton("Show Elements"));
p1.add(jbtSave = new JButton("Save Elements"));
p1.add(jbtLoad = new JButton("Load Elements"));
p1.setBorder(new TitledBorder("Display Array"));

jbtShow.addActionListener(this);
jbtSave.addActionListener(this);
jbtLoad.addActionListener(this);

this.getContentPane().add(p1,BorderLayout.NORTH);
}

public static int[] getArray() // creates the user defined array
{
int array[] = new int[10];
// Read all numbers
for (int i=0; i<array.length;i++)
{
//try
{
String numString = JOptionPane.showInputDialog(null, "Enter a number:","The Array Counter", JOptionPane.QUESTION_MESSAGE);
//Convert string into integer
array[i]=Integer.parseInt(numString);
}

/* catch (Exception ex)
{
JOptionPane.showMessageDialog(null,"That value is too large");
}
catch (Exception ex)
{
JOptionPane.showMessageDialog(null,"That value is too small");
}*/
}
return array;
}


public void actionPerformed(ActionEvent e)
{
if(e.getSource()==jbtShow)
{
String tempString;
int a;
tempString = arrayValue.getText().trim(); //take the field and trim it
a=(new Integer(tempString)).intValue(); //convert it to a int
int indexValue = array[a];
arrayElement.setText(String.valueOf(indexValue));
}

}
}

i am trying to get something like this to work....

class filling{
filling(){}
void put_it_in(){//put code here};
}

class taco {

public filling inside[];

taco(){

filling meat;
filling lettuce;
filling sour_cream;

inside[] = {meat, lettuce, sour_cream};

}
}//gives me a missing ; error

@ The Terk - You look like you have your listeners set up correctly. Maybe write a small loop that will attempt to read the array in one of your listeners. Have it dump its output to the console for debugging. If you start getting null pointer exceptions, something is wrong when you hand the array to your listener function here.

And when you say integer, do you mean the int primitive type or objects of class "Integer"? integer objects have some different properties than int primitive types.

@ericgl - first, the filling method is a constructor right? It should read as "public filling(){...(code here)...} You also do not need a semicolon after the putitin method unless filling is an abstract class and putitin is an abstract method of that class.

Nex time, for my own readability, pretty please use the tags.

Happy hacking!



EDIT - And wow. I just realized that this is an incredibly old thread thats been dug up by someone else. Please disregard my post.
