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:
append(): This method appends a string to the created/ declared StringBuilder object.
capacity(): This method gets the capacity of the StringBuilder which is gotten by the formula 16 + number of characters including white spaces.
charAt(index): This method returns the character at the specified index in the StringBuilder object.
