In this video explain functions of StringBuilder , before explain what is StringBuilder.
Lectures are not in series?
StringBuilder is just another inbuilt java class for various functions that string lacks in. StringBuilder provides a mutable sequence of characters that means when you make change, you are actually making change in that stringbuilder object, while in string this does not happen. Likewise, other functions that make it useful have been discussed in the video. You can refer to the documentation for a detailed explanation but I don’t think that’s required as of now.
