You can try any one

// Read from src/resources folder
InputStream in = getClass().getResourceAsStream("/resources/abc.txt");

Must read A Visual Guide to Layout Managers.

Here is some points from your code:

• Always use SwingUtilities.invokeLater() to initialize the GUI
• Follow Java Naming convention.
