Thread: change to swing format

For my school project i made a game but i didn't add imports, i have been told i need to have imports and it needs to be in a normal swing format or i will not pass

I was wondering if anyone can help me to change my code to swing format please. any advice will be appreciated

my code is

public class TextTwist extends javax.swing.JFrame
 implements java.awt.event.ActionListener
{
 
  // hard code, should be picked from a Problem class
  private String[] letters = {"F","O","C","I","E","F"};
 
  // hard code, should be picked from a Problem class
  private String[] solutions = {"ICE","OFF","FOE","FOCI","OFFICE"};
 
  // required designer variables
  private javax.swing.JButton[] letterButtons;
  private javax.swing.JButton enterButton;
  private javax.swing.JButton clearButton;
  private javax.swing.JLabel bufferLabel;
 
  private javax.swing.JLabel[] solutionLabels;
 
  public TextTwist()
  {
     // needed for the Windows GUI
     initializeComponent();
  }
 
 
  // these are the GUI components
  private void initializeComponent()
  {
     this.letterButtons = new javax.swing.JButton[6];
 
     for (int i=0;i<this.letterButtons.length;i++)
     {
       this.letterButtons[i] = new javax.swing.JButton();
     }
 
 
     this.solutionLabels = new javax.swing.JLabel[solutions.length];
     for (int i=0;i<this.solutions.length;i++)

i need some help with: After all the soulotions have been found how do i get the program to move on to the next one String?

--- Update ---

please help me

get the program to move on to the next one String?

Can you explain what that means?
What happens when the program executes?
What should the user do?

I would like there to be another set of letters and anther souloution, and one is picked at
random

Put the data (the two arrays) into a class, create many instances of that class and put the instances in a list where they can be chosen randomly.
