Mansfield on Reusability

"A frequent argument for OOP is it helps with code reusability, but one can reuse code without OOP--often by simply copying and pasting."

Quote Manager Project -- Day 4

I set up a project in IDEA. It's time to start hacking together some GUI code. The first task I am looking to complete is to simply add a new quote to the XML file.

OK, so let's do some GUI work. Hopefully I will be able to write a test or two along the way... Here's what I'm starting with:

package com.redsquirrel.quotes.gui;

public class MAIN {
    public static void main(String[] args) {
        new QuoteManagerPanel();
    }
}

Here's the code that did it:

package com.redsquirrel.quotes.gui;

import javax.swing.JFrame;

public class MAIN {
    private static final String TITLE = "Quote Manager";

    public static void main(String[] args) {
        JFrame frame = new JFrame(TITLE);

        frame.getContentPane().add(new QuoteManagerPanel());

        frame.pack();
        frame.setVisible(true);
    }
}

package com.redsquirrel.quotes.gui;

import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextArea;

public class QuoteManagerPanel extends JPanel {

    public QuoteManagerPanel() {
        add(new JLabel("Quote: "));
        add(new JTextArea(3, 15));
    }
}
