Please help I have problems regarding inputing a value into an array with gui

[kenrocks]

i have 2 classes 1 main with methods and a gui file on the mainfile I have an aDD method.

public void aDD(JTextField a, String[] r)
    {
        int x=0;
        while(x<r.length)
        {
            r[x]=a.getText();
            x++;
        }
 
    }

 if (z.getSource()== add)
        {   
            a3.aDD(f,x);
            f.setText("");
 
        }

If you want us to help you you have to be less vague: *what* exactly turns out
to be null? The array itself? Elements in the array? Something else? Was it
null before? Where did you notice it was null?

kind regards,

Jos

when a display button is clicked..the return value is null..only the first entry appears and the second remains as null

Again: *what* return value? And ActionListener doesn't supply you with a return
value. A first and second entry of *what*? You do have to be as exact as possible.

the entries ion the array made by this add button..

the entries ion the array made by this add button..

According to your code you put the same value in every entry (a.getText()). They
all should be equal. The getText() method can return an empty String "" but not
null. Or is there some other code that fiddles with the array values?

kind regards,

Jos
