If you want to hide the form frm_one do :

Code:

frm_one.setVisible(false);

If you do not want the frm_one to appear at all remove the line

Code:

new form_one().show();

in the mehod

Code:

public static void main(String args[])

when i change the code in the jbutton from this:

Code:

    private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
        form_two frmTwo = new form_two();
        frmTwo.setVisible( true );
    }

to this:

Code:

    private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
        form_two frmTwo = new form_two();
        frmTwo.setVisible( true );
        
        form_one.setVisible( false );
    }

this is the error that i get!?:

Code:

forms/form_one.java [30:1] non-static method setVisible(boolean) cannot be referenced from a static context
        form_one.setVisible( false );
                ^
1 error
Errors compiling form_one.

i understand that its because the creation of the form_one is in the scope of this fuction so how do i get the button to recognise form_one? cheers again.

Maybe you should do

Code:

this.setVisible(false);

because you cannot call directly setVisible without an object like this :

Code:

form_one frm = new form_one();
frm.setVisible(false);
