Reverse string order

On the Internet, we can see a reversed character written by someone else.Algorithm,

So I spent one or two minutes writing one. You are welcome to propose more optimized algorithms for everyone to learn and learn.

Code

Private   String Rev ( String Str)
{
Int Len =   0 ;
If (Str =   Null   | (Len = Str. length) <   2 )
Return STR;
Char [] C = Str. tochararray ();
Char TMP =   ' C ' ;
For ( Int I =   0 ; I < Len /   2 ; I ++ )
{
TMP = C [I];
C [I] = STR [Len - I -   1 ];
C [Len - I -   1 ] = TMP;
}
Return   New   String (C );
}
