What Is A Stringbuilder And What Are Its Use Cases? What Is The Diffe

1.	What Is A Stringbuilder And What Are Its Use Cases? What Is The Difference Between Appending A String To A Stringbuilder And Concatenating Two Strings With A + Operator? How Does Stringbuilder Differ From Stringbuffer?
Answer» StringBuilder allows manipulating character sequences by appending, DELETING and inserting characters and strings. This is a mutable data structure, as OPPOSED to the String CLASS which is immutable. When concatenating two String instances, a new object is created, and strings are copied. This could BRING a huge garbage collector overhead if we need to create or MODIFY a string in a loop. StringBuilder allows handling string manipulations much more efficiently. StringBuffer is different from StringBuilder in that it is thread-safe. If you need to manipulate a string in a single thread, use StringBuilder instead.
