Re paidia kai mia allh erwthsh, otan kanw Compile mia class ektos apo to: onoma_klashs.class ftiaxnei kai merika alla arxeia: onoma_klashs$1.class. Epeita de mporw na ta anevasw sto server epeidh exoun mesa "$", pws parakamptetai to provlhma ayto;

 

Το αρχείο onoma_klashs$1.class είναι η πρώτη ανώνυμη inner κλάση που έχει φτιάξει μέστα στο αρχείο onoma_klashs.class. Αν είχες δεύτερη ανώνυμη κλάση θα την ονόμαζε η Java onoma_klashs$2.class. Ένας πιθανός τρόπος θα ήταν να μην χρησιμοποιήσεις κάθόλου inner κλάσεις και να τις φτιάξεις σε ξεχωριστό αρχείο.
