Using the Java StringBuffer class

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 the StringBuffer class. It covers the inefficiency of string manipulations with String objects and how to substitute a StringBuffer object. 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!

Here is the introductory video on Strings:
