Re: [Eclipse] How to fix indentations.

On Sun, 16 Sep 2007 19:06:19 GMT, Lew expounded upon us in
comp.lang.java.help :


This program is meant to be a solution to a question on Roedy's beginner
projects page. http://www.mindprod.com/project/beginner.html
A simple GUI with a button. When you press it, the program displays one of a
number of preselected ?fortunes?.

I still have to figure out how to make the longer fortunes display without
opening a scroll panel. It would be nice if the jTextArea had a dynamic
sizing method. It might, but I haven't looked yet.

package fortuneTeller;

import java.util.ArrayList;
import java.util.Random;

/**

public class fortuneScreen extends javax.swing.JFrame {

public fortuneScreen() {
  initComponents();
}

private void initComponents() {
  randomJButton = new javax.swing.JButton();
  jScrollPane1 = new javax.swing.JScrollPane();
  fortuneTextArea = new javax.swing.JTextArea();
  exitJButton = new javax.swing.JButton();
  setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
  randomJButton.setText("Press for a Random Fortune");
  randomJButton.addActionListener(new java.awt.event.ActionListener() {
    public void actionPerformed(java.awt.event.ActionEvent evt) {
      randomJButtonActionPerformed(evt);
    }
  });
  fortuneTextArea.setColumns(50);
  fortuneTextArea.setRows(10);
  jScrollPane1.setViewportView(fortuneTextArea);
  exitJButton.setText("Exit");
  exitJButton.addActionListener(new java.awt.event.ActionListener() {
    public void actionPerformed(java.awt.event.ActionEvent evt) {
      exitJButtonActionPerformed(evt);
    }
  });

  javax.swing.GroupLayout layout =
    new javax.swing.GroupLayout(getContentPane());
  getContentPane().setLayout(layout);
  layout.setHorizontalGroup(
    layout.createParallelGroup(
      javax.swing.GroupLayout.Alignment.LEADING).addGroup(
        layout.createSequentialGroup().addGroup(
          layout.createParallelGroup(
            javax.swing.GroupLayout.Alignment.LEADING).addGroup(
              layout.createSequentialGroup().addGap(
                76,76,76).addComponent(randomJButton).addGap(
                  88,88,88).addComponent(exitJButton)).addGroup(
                    layout.createSequentialGroup().addContainerGap().
                      addComponent(
                        jScrollPane1,
                        javax.swing.GroupLayout.DEFAULT_SIZE,
                        480,
                        Short.MAX_VALUE))).addContainerGap()));
  layout.setVerticalGroup(
    layout.createParallelGroup(
      javax.swing.GroupLayout.Alignment.LEADING).addGroup(
        layout.createSequentialGroup().addGap(
          39, 39, 39).addComponent(
            jScrollPane1,
            javax.swing.GroupLayout.PREFERRED_SIZE,
            31, javax.swing.GroupLayout.PREFERRED_SIZE).addGap(
              41,41, 41).addGroup(
                layout.createParallelGroup(
                  javax.swing.GroupLayout.Alignment.BASELINE).
                    addComponent(randomJButton).addComponent(exitJButton)).
                      addContainerGap(21,Short.MAX_VALUE)));
  pack();
}

private void exitJButtonActionPerformed(java.awt.event.ActionEvent evt) {
  System.exit(0);
}

private void randomJButtonActionPerformed(java.awt.event.ActionEvent evt) {
  Random generator = new Random();
  int randomIndex = generator.nextInt(18);
  String fortuneDisplay = "Fortune number: + String.valueOf(randomIndex)" +
  " " + fortunes.get(randomIndex);
  fortuneTextArea.setText(fortuneDisplay);
}

public static void main(String args[]) {
  java.awt.EventQueue.invokeLater(new Runnable() {
    public void run() {
      new fortuneScreen().setVisible(true);
    }
  });
}

      fortunes.add("I Like food");

      fortunes.add("Wrinkles should merely indicate where " +
       "smiles have been.");
      fortunes.add("A piano will fall near you at 2pm");
      fortunes.add("Live long, and prosper");
      fortunes.add("You will be assimilated");
      fortunes.add("I am nothing");
  }
}

Ok, Lew... I moved the creation of my list of fortunes out to where the
screen elements are created and I changed the listOfFortunes to "fortunes" so
that if I were to make it a different structure later on, the name won't be
misleading. And I cleaned up the indentation as best as I could. It seems
to be alot of work to make a program look nice for posting on usenet, but
that's ok... I don't mind the effort if I can gain some knowledge from it.

Once I moved the declaration out to where the rest of the private variables
are declared, Eclipse gave me a warning which I resolved by making the same
change as you pointed out

private static ArrayList<String> fortunes = new ArrayList<String>();

I know about programming to an interface, not an implementation but I don't
see where that comes into play in this program.

Further, I don't claim to know what Netbeans did when it created the
initComponents method. I guess the "beauty" of an IDE is that it takes care
of all that stuff for you. However, I am going to do some studying on it and
see if I can figure it out.
