Problemas com campo tipo date

Programação Java
#1

Pessoal tenho um campo Data na minha tabela no Mysql quando esse campo contem algum valor ele retorna numa boa mas se ele estiver vazio ele dar erro, para chama ele eu usu o getDate, getString e dar a mesmo erro.

chamo assim:
System.out.println("" + con.getResultSet().getDate(“data”));
ou assim:
System.out.println(con.getResultSet().getString(“data”));

error:
java.sql.SQLException: Value ‘0000-00-00’ can not be represented as java.sql.Date

#2

Pessoal consiguir resolver era só fazer um tratamento de erro, ficou assim.

try{
System.out.println(con.getResultSet().getString(“data”));
}catch (SQLException e){
System.out.println(“catch”);
}finally{
System.out.println(“finally”);
}
