באמצעות Command Design Pattern ניתן למדל פעולות שונות אשר מבוצעות בסדר מסוים באופן שבו כל פעולה מיוצגת באמצעות אובייקט נפרד, כל האובייקטים מוחזקים בסדר שנתון לשליטתנו והתמיכה ב-undo קלה למימוש. הוידאו קליפ הבא מסביר כיצד לעשות זאת.

את קוד המקור שמופיע בוידאו ניתן להוריד בקישור הבא command. תרשים ה-UML הבא מספק הסבר נוסף.

Haim is one of the best lecturers i have ever met so far! His passion and love to the development world is helping him to teach the students in the best way we could ask! The way he teaches is very organized, his amazing website (abelski.com) contains all the materials you just need, and its constantly updating...

I had the honor to learn from Haim during my studies for Bsc in computer science at HIT. Haim is one of the most professional lecturer I met, he has enormous knowledge in many fields and he teaches with one major goal in mind - to train and authorize professional engineers, and to handle them with the most important tool everyone should have - the ability to learn ,to research and to know how to solve problems, set goals and achieve them. Haim is very caring for each and every student of his and will spend time, effort and energy for every student and know how to explain everything to anyone in his own way so any individual will grow and get the best of itself. I recommend anybody who wants to learn and get tools for his professional career to contact Haim and be one more of the endless growing circle of Knowledgeable students of Haim!

Life Michael has profound knowledge about many programming languages, their history, their strength and weaknesses and computing and information technology in general, including many areas, like enterprise systems, mobile, embedded and real time, open source and much more. He delivers the material very clearly, in an interesting way, allowing much time to questions and answers, until everyone is satisfied. His lectures and courses are highly recommended!
