Description

In this tutorial, we take a look at the StringBuilder class.
Strings are immutable meaning they cant e destroyed once created, but a StringBuilder is mutably making it the best option for string manipulation.
The following are a few methods amongst many:

length(): This method returns the length of the StringBuilder object which is the total number of characters.

subString(index): This returns a substring of the StringBuilder object starting from the index specified to the end of the StringBuilder object which is the total length of the StringBuilder object.

setCharAt(index): This changes the character at the specified index.
