My mad lib program was able to store my three notepad text: noun, verb, and story. I would
like to find out what is the best way to make it display my result randomize my story from notepad?
once everything is stored?

  JTextField output = new JTextField(20);


  public static void main()
  {
     StoryProject frame = new StoryProject();
     frame.setBackground(Color.YELLOW);
     frame.setSize(900, 300);
     frame.setTitle("randomize story");
     frame.createGUI();
     frame.setVisible(true);
  }

     window.add(panel);

     mytextButton.addActionListener(this);
     allverbButton.addActionListener(this);
     anounButton.addActionListener(this);
     JLabel outputLabel = new JLabel("The mad lib will be: ");
     JButton button = new JButton("START");

     panel.add(mytextButton);

Please avoid needlessly bumping your thread.

Am i using scanner and fileinput stream correctly to read three text?
I wanted to change my % and # into different word.

You can check this by seeing if the contents of these files have been successfully read in. Though I will note that you are comparing Strings using the == operator, which compares their locations in memory. Use the equals() method, which checks their literal values.
