Understanding Strings and String operations in Java
This series of videos is suitable for programmers with some programming or Java experience who want to learn object-oriented programming and dig deeper into some other Java features. This video is an introduction to Strings -- how they're represented in memory, how they're indexed, and how to compare them and search through them. This video is suitable to watch after reading Chapter 7 of Java, Java, Java: Object-oriented problem solving, by Morelli, Walde, and Hoffman. However, the video is very straightforward and can also stand alone or accompany any other textbook that has introduced Java Strings and a little bit of object-oriented programming. Let's have some fun learning to program in Java!
The classes in this video are in my github repository, available here:
