Eu recém tinha terminado o meu código e fechei o netbeans (eu salvei tudo certinho) aí eu resolvi abrir dnv uns minutos depois e o meu código estava cheio de erros pra todos os lados. Ele estava rodando normalmente antes e executava o que eu tinha feito perfeitamente, alguém pode me ajudar?

#2

Roda o código e passa a linha que está dando erro.

#3

Pode ter mudado a versao do java, ou o netbeans perdeu a referencia da pasta da jdk
