A variável objectarray precisa ser do tipo Insert[], você declarou como Object[].

J
Junior_Mateus

Obrigado, deu certo Aki. Mas só pra tirar uma dúvida teria como converte essa classe Insert em um object, porque objectarray fica com um aviso pedindo pra ser declarada como Object[].

Insert já é um Object, toda classe Java deriva de Object.

Onde fica esse aviso?
Posta o código completo.

Inviável ler seu fonte dessa forma…
Usa o botão de texto pré-formatado </> ao postar código no fórum.

Algum motivo especial para não utilizar generics no seu código?

Seu método getAccountDetailsBetweenDates tem quase 400 linhas, isso não se faz, dá uma refatorada e quebra ele em métodos (ou classes) menores.
Um método, para permanecer legível, não deveria passar de 20 linhas.

J
Junior_Mateus

Eu sou novo Aki no fórum ainda não sei utilizar as ferramentas direito. Obrigado pelas dicas vou tentar da enxugada no código e utilizar o generics.
