This video tutorial covers various string methods in Java, including character and index retrieval, substring extraction, concatenation, trimming, case conversion, splitting, and replacing. The tutorial provides practical examples and explains how these methods can be used in programming tasks.

What is the index of the first character in a Java string?

• 0

• 3

• 2

• 1

Which method would you use to find the position of a character in a string?
