Why arnt my variables being seen in Java?

Question

Hi, trying to figure out why my JTextField 'scInput' cannot be seen in another class?

I define it in class 'gui' as

private JTextField scInput;

within the public class

public class Gui extends JFrame
implements ActionListener

But when trying to call it in another class, its not being resolved...

public String setStockCode()
{
new Gui();
stockCode = scInput.getText();
}

even after i make a new instance of Gui()

Also, changing it to public from private does nothing, and theyre in the same package.

anyone got any ideas?

Thanks

Nope, like i said, changing it to public does nothing, since ive made an instance of the method its called in, it can read the private ones, but i did change it and it still doesnt work, scInput (textfield) cannot be resolved...

Answer 1

define it as static then call it directly from the class name
gui.scInput.getText();

and dont forget to creat the scInput object in ur main class

Answer 2

I think from looking at the code above that your trying to declaring an instance wrong. It your going to call it from another class you have to create a variable based upon that class, such as:

Gui example = new Gui();

Declaring it like you did only makes it local to that class. I'm not 100 percent but it's worth a try

Answer 3

You cant use it in another class because you've declared it private.
Change it to public JTextField scInput in the gui class.

Answer 4

Besides changing the scInput to public or creating the accessor method ....

Don't forget to create your scInput object.

scInput = new JTextField();

Answer 5

it can't be accessed because you set it to private.. it is best that you add a public getter method like

public Gui getScInput(){
return this.scInput;
}

in your class. So you can call this method if you want to get the value of scInput.

Answer 6

i got the same answer as above, public instead of private..
but i wanna be sure of something first, did u create the object using the new operator?

Answer 7

you are not able to access it because the variable is private. if you make it public, you will be able to access it.
