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;

public class Hide_Show_Label_with_Icon extends javax.swing.JFrame {

initComponents();
}

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) {
