To fazendo um projeto aqui pra faculdade e estava querendo fazer uma validação de datas dessa forma:
Quando o usuário selecionar o mês na JComboBox de meses apareceria na JComboBox de dias os dias correspondentes à primeira escolha.
Exemplo: O usuário selecionou “01” na comboMes ai deveria aparecer os dias correspondentes a janeiro.
Alguém pode me ajudar?

É só você colocar um Listener no combo no evento itemStateChanged assim quando mudar o item carrega o combo de dias conforme o mês selecionado.
