We demonstrate the existence of Euclidean and Hermitian LCD codes over finite fields with various parameters. In addition, we provide a method for constructing multiple Hermitian LCD (self orthogonal, self dual) codes from a given Hermitian LCD (self orthogonal, self dual) code, as well as a method for constructing Euclidean (Hermitian) LCD codes with parameters $[n+1, k+1]$ and $[n,k+1]$ from a given Euclidean (Hermitian) LCD code with parameters $[n,k]$ over finite fields. Finally, we provide some findings on $\sigma$-LCD codes over finite fields.
