entonces soy nuevo en Processing y básicamente estoy haciendo un programa que cuando se ejecuta, abre una ventana con 4 imágenes diferentes, cada una de las imágenes tiene una descripción debajo. En los métodos a continuación, creé dos métodos aleatorios, uno para el número de reseñas y el otro para los comentarios de revisión, me gustaría que los comentarios no se generen todo el tiempo para cada película, más como aparecer al azar, porque también mucho caos tratando de leerlos a todos. También para verificar el clima, puedo agregar matrices juntas de cadena e entero para el valor promedio del número de revisión.

A continuación se muestra el código, agradecería su ayuda. Gracias.
