StringBuilder() constructor is used to initialize a new instance of the StringBuilder class which will be empty and will have the default initial capacity. StringBuilder is used to represent a mutable string of characters. Mutable means the string which can be changed. So String objects are immutable but StringBuilder is the mutable string type. It will not create a new modified instance of the current string object but do the modifications in the existing string object.
public StringBuilder ();
Here 16 is the default capacity.
- Using this constructor will set the string value of the current instance to String.Empty.
- Capacity is set to the implementation-specific default capacity. Here it is 16.
