Variables
String handling - Efficiency
• A string is an immutable sequential collection of Unicode characters, typically used to
represent text. A String is called immutable because its value cannot be modified once it has
been created.
• Methods that appear to modify a String actually return a new String containing the
modification. If it is necessary to modify the actual contents of a string-like object,
System.Text.StringBuilder class is more efficient. This class allows string modifications to be
done without the overhead of object creation and garbage collection.
