Just use a Scanner

    private javax.swing.ComboBoxModel getInterestRatesModel() {
	javax.swing.DefaultComboBoxModel result = null;
	String filename = "rates.txt";
	java.util.Scanner s = null;
	try {
	    result = new javax.swing.DefaultComboBoxModel();
	    s = new java.util.Scanner(new File(filename));
	    while(s.hasNextLine()) {
		result.addElement(s.nextLine());
	    }
	}
	catch(IOException e) {
	    e.printStackTrace();	
	}
	finally {
	    try { s.close() ; } catch(Exception e) { /* ignore */ }	
	}
	return result;
    }
