Can not pull data from the has map

[jon ladd]

I can not get the find button to return the data from the hash map. I have tried everything I can think of with using the key, get, from the hashmap.
If more code is need let me know.

 public void actionPerformed (ActionEvent e)
{
    Map myObjects = new HashMap();
    Button buttonObj = (Button) e.getSource();
    if (buttonObj == addButton) 
    {
        delButton.setEnabled(false);
        if ((partField.getText().equals ("")) || (quantField.getText().equals("")) || (descField.getText().equals("")))
            msgs.setText ("You have a field that is empty.");
        int pnn = (new Integer (partField.getText())).intValue();
        if (pnn > param)
            msgs.setText("The part number is too big");
        else{
        int qnn = (new Integer (quantField.getText())).intValue();
        Part temp = new Part (pnn, descField.getText(), qnn);
        if ((myObjects.get(new Integer(pnn))) != null)
            msgs.setText("Duplicate object");
        else{
            myObjects.put((new Integer(pnn)), temp);
            msgs.setText("Add Successful");
        }
        }
    }
    if (buttonObj == findButton) 
    {
        delButton.setEnabled(false);
        int pnn = (new Integer (partField.getText())).intValue();
        if ((myObjects.get(new Integer(pnn))) != null)
        {    
            Part temp = (Part) myObjects.get(new Integer (pnn));
            descField.setText (temp.getDesc());
//            quantField.setText (temp.getQuantity());
            delButton.setEnabled(true);
        }
        else
            msgs.setText("Part doesn't exist" + pnn);
    }

The problem here might become a little bit clearer if you split your method into three functions:

public void actionPerformed (ActionEvent e)
{
    Map myObjects = new HashMap();
    Button buttonObj = (Button) e.getSource();
    if (buttonObj == addButton) 
    {
        this.addButtonActionPerformed();
    }
    if (buttonObj == findButton) 
    {
        this.findButtonActionPerformed();
    } 
}
private void addButtonActionPerformed(){
        delButton.setEnabled(false);
        if ((partField.getText().equals ("")) || (quantField.getText().equals("")) || (descField.getText().equals("")))
            msgs.setText ("You have a field that is empty.");
        int pnn = (new Integer (partField.getText())).intValue();
        if (pnn > param)
            msgs.setText("The part number is too big");
        else{
        int qnn = (new Integer (quantField.getText())).intValue();
        Part temp = new Part (pnn, descField.getText(), qnn);
        if ((myObjects.get(new Integer(pnn))) != null)
            msgs.setText("Duplicate object");
        else{
            myObjects.put((new Integer(pnn)), temp);
            msgs.setText("Add Successful");
        }
        }
    }
}
private void findButtonActionPerformed(){
        delButton.setEnabled(false);
        int pnn = (new Integer (partField.getText())).intValue();
        if ((myObjects.get(new Integer(pnn))) != null)
        {    
            Part temp = (Part) myObjects.get(new Integer (pnn));
            descField.setText (temp.getDesc());
//            quantField.setText (temp.getQuantity());
            delButton.setEnabled(true);
        }
        else
            msgs.setText("Part doesn't exist" + pnn);
}

Now, every time you enter the action performed method, a new HashTable is created and assigned to the myObjects local variable. If the find button is pressed, it calls the find button's method.
What you want to do is make the myObjects a member variable. It will then be accessible from every method. Just remember that you only need to initialize it once (not on every button click), or else you will have the same problem.
