Como copiar valores de un Jlist a otro en Java?

[Rekker]

Buen dia chicos
Tengo un programa en el cual se introduce por teclado el nombre del alumno y se selecciona la jornada para matricular.
al dar clic en el boton matricular, coloca el nombre en la lista dependiendo la jornada elegida. si se trata de introducir en blanco o un nombre ya registrado mostrara error.
con el boton retirar debe borrar el nombre de la lista seleccionada.



Mis problemas son los siguientes:
Tengo el boton programado para que elimine de la lista diurna, pero en la nocturna me dice que no seleccione ningun elemento, trate de colocar el mismo codigo, pero eliminaba registros de las dos listas, es decir si queria eliminar uno de la nocturna lo hacia pero a su vez eliminaba uno de la diurna
Necesito borrar el registro dependiendo de la lista seleccionada.
Eliminando valores de la lista diurno




eliminando valores de la lista nocturno


El codigo que tengo es este:

se debe copiar uno o todos los valores de la lista diurna a la nocturna o vicecersa y quitar dicho valor de la lista de origen, pero estos si no tengo ni la mas minima idea de como programarlos, lei en otros sitios y me dice que con arrays, pero ni idea

Agradezco a quien me pueda ayudar con mis problemas
