I googled for “java collection cheat sheet” sometimes ago. And I found single one having a class diagram showing an inheritance tree of many classes of java collection framework. In the header part, there was some little discussion about some collection classes.
But that sheet were neither pointing out small aspects of any class nor comparing any class with other to decide which class may suite to someones project.
Finally there is a Java Collection Doodle Cheat Sheet. This sheet has comparison of 15+ collection classes using flow chart. So anyone can choose the best collection class to their project.
This sheet also has small aspects of most collection classes.
Refer the below screen shot from that sheet. And visit original article to download the sheet.
