A mensagem é bastante clara:

PrimeiroComando has been compiled by a more recent version of the Java Runtime (class file version 56.0), this version of the Java Runtime only recognizes class file versions up to 52.0

Ou seja, você compilou a classe PrimeiroComando com um JDK de uma versão, mas tentou executar com um JRE de versão inferior.

Utilize um JRE da mesma versão que seu JDK.
