Tstringbuilder.create can be without parameters

procedure TForm1.Button1Click(Sender: TObject);
var
　sb: TStringBuilder;
begin
　sb := TStringBuilder.Create;
　sb.Append('Embarcadero');
　sb.Append(' CodeGear');
　sb.Append(' Delphi');
　sb.Append(' 2009');
　ShowMessage(sb.ToString); {Embarcadero CodeGear Delphi 2009}
　sb.Free;
end;

Tstringbuilder.create can be initialized with a string of characters; Other overloads are not very useful

procedure TForm1.Button2Click(Sender: TObject);
var
　sb: TStringBuilder;
begin
　sb := TStringBuilder.Create('Delphi ');
　sb.Append(2009);
　ShowMessage(sb.ToString); {Delphi 2009}
　sb.Free;
end;

End.
