How to (and how not to) compare Strings in Java; Intro to Java (full course) Lesson 3 Video 3
This series of videos is suitable for programmers with minimal (or no) programming experience who want to learn Java. You cannot compare Strings with the relational operators (well, you can, but you won't be comparing the characters in the string), so this video explains why and shows the proper way to compare strings.
There is a suggested (free) book below that you could read along with the videos lessons. However, the video is very straightforward and can also stand alone or accompany any other introductory Java textbook. Let's have some fun learning to program in Java!
