    Default how to get return values from a button to main program.


    I have a main program which has a button Authenticate. On click of authenticate open a form for auth which has USERNAME FIELS AND PASSWORD.
    If entered fields are true then enable editing of jtable in main program..

    Basically something like this :
    //main program
    Authenticate.addActionListener(new ActionListener()
    public void actionPerformed(ActionEvent ae)
    UpdateAuth ua=new UpdateAuth();// opens form which has username and pass for authentication

    //need code here for enabling table
    enable table editing


    // form open for auth..(class UpdateAuth )

    private String SigninMouseClicked(java.awt.event.MouseEvent evt) {
    String aname=Aname.getText();
    String apass=Apassword.getText();
    if(aname.equals("") && apass.equals(""))
    JOptionPane.showMessageDialog(null,"Enter login name or password","Error",JOptionPane.ERROR_MESSAGE);
    if(!(aname.equals("") && apass.equals("")))
    if(aname.equals("harshil") && apass.equals("harshil123"))
    String s="mactus"; /// if username and password is success enable table editing in main program
    return s;

    else if (!aname.equals("mactus") && !apass.equals("mactus123"))
    return null;

    Can you explain what the problem with the code is?

    Please edit your post and wrap your code with
