Looping patterns in Java (summing, find largest value, sentinel); Intro Java course Lesson 4 Video 2

This series of videos is suitable for programmers with minimal (or no) programming experience who want to learn Java. This is the nineteenth video in the Introductory Java series, and the second video in lesson 4 (looping). In this video we're going to look at some common looping patterns, such as summing values encountered in a loop, finding the largest or smallest value, and looping until a specific value is reached. We'll iterate over Strings to illustrate these patterns, and we'll further discuss the increment operator.

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!
