JTextArea does not show up until you select it

Question

My code creates a basic Sign Up screen, but the JTextArea objTE1 does not show up until you select where the text would be.

import java.awt.*;
import javax.swing.*;
public class SignUpScreen extends Frame
{
    SignUpScreen()
    {
        super("No Layout Manager");
        setLayout(null);
        setTitle("Sign Up");
        setSize(400,700);
        show();
    }
    public static void main(String[] args)
    {
        Frame objFrame;
        JTextArea objTE1;

        JCheckBox objCheckMail;
        JCheckBox objCheckEmail;
        JCheckBox objCheckPhone;

        Button objButtonFinish;
        Button objButtonCancel;

        TextField objEnterEmail;
        TextField objEnterAdress;
        TextField objEnterPhone;
        TextField objEnterUsername;
        TextField objEnterPassword;
        TextField objConfirmPassword;


        objFrame = new SignUpScreen();
        objTE1 = new JTextArea();
        objCheckMail = new JCheckBox("Mail Notifications");
        objCheckEmail = new JCheckBox("Email Notifications");
        objCheckPhone = new JCheckBox("Text Notifications");

        objButtonFinish = new Button("Sign Up");
        objButtonCancel = new Button("Cancel");

        objEnterEmail = new TextField("Enter Email",0);
        objEnterAdress = new TextField("Enter Adress",0);
        objEnterPhone = new TextField("Enter Phone Number",0);
        objEnterUsername = new TextField("Enter Username",0);
        objEnterPassword = new TextField("Enter Password",0);
        objConfirmPassword = new TextField("Confirm Password",0);

        Font pagehead = new Font("Verdana", Font.BOLD, 24);
        objTE1.setFont(pagehead);
        objTE1.setForeground(Color.BLUE);

        objTE1.setText("     Sign up for the\nWatermelone Mail List");
        objTE1.setEditable(false);
            objTE1.setVisible(true);


        objTE1.setBounds(50, 75, 300, 70);

        objCheckMail.setBounds(100,450,200,50);
        objCheckEmail.setBounds(100,500,200,50);
        objCheckPhone.setBounds(100,550,200,50);

        objEnterEmail.setBounds(100,150,150,20);
        objEnterAdress.setBounds(100,200,200,20);
        objEnterPhone.setBounds(100,250,200,20);
        objEnterUsername.setBounds(100,300,200,20);
        objEnterPassword.setBounds(100,350,200,20);
        objConfirmPassword.setBounds(100,400,200,20);

        objButtonFinish.setBounds(50,600,120,60);
        objButtonCancel.setBounds(220,600,120,60);


        objFrame.add(objTE1);

        objFrame.add(objEnterEmail);

        objFrame.add(objButtonFinish);
        objFrame.add(objButtonCancel);

        objFrame.add(objEnterUsername);
        objFrame.add(objEnterPassword);
        objFrame.add(objConfirmPassword);
        objFrame.add(objEnterAdress);
        objFrame.add(objEnterPhone);

        objFrame.add(objCheckMail);
        objFrame.add(objCheckPhone);
        objFrame.add(objCheckEmail);
    }
}

Answer 1

1. Don't use a "null layout". Swing was designed to be used with layout managers.
2. Use new JTextArea(5, 30); when creating a text area. That is specify the rows/columns for the text area.
3. Don't use AWT components in a Swing application. Swing components start with a "J", JButton, JTextField, JFrame.
4. Don't use show(). The proper method is setVisible(true)
5. Create your GUI components on the Event Dispatch Thread (EDT).
6. The setVisible(true) needs to be done AFTER all the components have been added to the frame.

I suggest you read the section from the Swing tutorial on Using Layout Managers for some examples of using layout managers and on to use the EDT.
