    Default Re: How can I append text in JTextArea from another class

    I have tried something like this but it is not showing anything in the textArea. i have two classes A and B
    Class A

    Class A extends javax.swing.JFrame{
    private JtextArea myTextArea;
    A( ){
    myTextArea = new JtextArea;
    }
    public void setArea(String mess){
    myTextArea.Append(mess);
    }
    }

    Class B
    Class B{
    A newA;
    B( ){
    newA = new A;
    }
    //i have this line which is supposed to append text in myTextArea in class A
    newA.setArea(“message”);
    }
