Applying Python To Modify Java Code

Python script intended to open each Java's project file, add the license term on the start of the file as a Java comment and writing it to the disk. 1) You'll need a Python interpreter. Check this out in http://python.org. 2) You'll need to enter the root file directory of the Java project, like python AddLicense.py ${path} where ${path} defines user project root directory. 3) See http://fcmanager.wiki.sourceforge.net 1:# Python script to add the LGPL notices to each java file of the FileContentManager project. 2:import os, glob, sys 3:License = """\ 4:/** 5:*FileContentManager is a Java based file manager desktop application, 6:*it can show, edit and manipulate the content of the files archived inside a zip. 7:* 8:*Copyright (C) 2008 9:* 10:*Created by Camila Sanchez [http://mimix.wordpress.com/], Rafael Naufal [http://rnaufal.livejournal.com] 11:and Rodrigo [rdomartins@gmail.com] 12:* 13:*FileContentManager is free software; you can redistribute it and/or 14:*modify it under the terms of the GNU Lesser General Public 15:*License as published by the Free Software Foundation; either 16:*version 2.1 of the License, or (at your option) any later version. 17:* 18:*This library is distributed in the hope that it will be useful, 19:*but WITHOUT ANY WARRANTY; without even the implied warranty of 20:*MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Preparing for SharePoint TechCon, January 27th - 29th

Jul 21, 2013 · Eric Senunas

In Ruby:

v=[1,5,6,7,9,10];sum = v.reduce(:+);count=0;index = (0...v.size).detect { |i| count += v[i]; count * 2 == sum};index == nil ? nil : index + 1

Result: index = 4

How to Combine REST Services with EJB 3.1

Dec 02, 2009 · Geertjan Wielenga

Good introduction to combine REST services with EJB! BTW, I think is the @EJB annotation which enables bean dependency injection by the container instead of the @Stateless annotation.

JTable per-row Editors and Renderers

Feb 10, 2009 · Mr B Loid

@MarkThornton

"You supposed to throw an exception instead of using an assert. However this doesn't change the problem with respect to testing --- you have to provide a valid value."

What if the unnecessary values for testing would be substituted by "NullObjects"?

Then, the code would look like this:

testSecureHouse() {
 Door door = new Door();
 Window window = new Window();
 House house = new House(door, window,
 HouseTest.createRoofForTest(), HouseTest.createKitchenForTest(), 
 HouseTest.createLivingRoomForTest(), 
 HouseTest.createBedRoomForTest());
 
 house.secure();
 
 assertTrue(door.isLocked());
 assertTrue(window.isClosed());
}

If Roof, Kitchen, LivingRoom and BedRoom were interfaces, the null objects can have the same contract (implementing the same interface). The null objects can have only one instance because there is no need to have a lot of instances of the same NullObject. Of course they don't need to be hard-coded, they can be configured and created with Test Data Builders. Each of the collaborators instantiate Null Objects that it depends.

JTable per-row Editors and Renderers

Sometimes ago I blogged about ways of indicating the absence of an object:

One interesting comment I received about using Assert to validate input:

"There's a document in the JDK docs titled Programming With Assertions that says:

Do not use assertions for argument checking in public methods"
