Ola pessoal...
venho desenvolvendo em jgoodies algum tempo...
gostaria de saber se eh possivel tratar as RuntimeException e as Exceptions nos metodos set
dos beans... veja um exemplo de um metodo set...
public void setNome(String nome) {
if (nome == null) {
throw new IllegalArgumentException("nome nao pode ser null");
} else if (nome.equals("") || nome.equals(" ")) {
throw new IllegalArgumentException("nome nao pode ser vazio");
}
String valorAntigo = this.nome;
this.nome = nome;
this.firePropertyChange(PROPERTY_NOME, valorAntigo, this.nome);
}
qdo o campo do jTextField fica vazio lanca uma IllegalArgumentException...
