It gave me confusing results. It was like the project ran too fast to ever 
display the label. I thought this was nonsense, so I created the below project.

The big question now becomes how do I (using the below project) get jLabel1 to 
be visible while the project is executing in the for loops?

Information about 3 of my button clicks:

Start run jLabel1 is visible :-)

(1st button press)
jLabel1 disappears at end of method and never comes back up!

(2nd button press)
jLabel1 never is seen

(3rd button press)
jLabel1 never is seen

//Code:

package hide_show_label_with_icon;

import java.util.logging.Level;
import java.util.logging.Logger;

public class Hide_Show_Label_with_Icon extends javax.swing.JFrame {

    public Hide_Show_Label_with_Icon() {
        initComponents();
    }

    @SuppressWarnings("unchecked")
    private void initComponents() {

        jButton1 = new javax.swing.JButton();
        jLabel1 = new javax.swing.JLabel();

        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

        jButton1.setText("jButton1");
        jButton1.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                jButton1ActionPerformed(evt);
            }
        });

        jLabel1.setText("jLabel1");

        javax.swing.GroupLayout layout = new
javax.swing.GroupLayout(getContentPane());
        getContentPane().setLayout(layout);
        layout.setHorizontalGroup(

        pack();

        System.out.println("jLabel1.isVisible is " + jLabel1.isVisible());

        jLabel1.setVisible(true);

        for (int i = 0;i < 100000; i++)
