Eclipse Shortcuts

Editors are an integral part of a programmer’s life. If you have good proficiency in using an editor thats a great advantage. It comes very handy to debug. Traditional notepad and SOPs (System.out.println) are the way we start learning a language but that is not sufficient, so beginners start using an IDE and most importantly know the shortcuts.
