Pessoal, como resolvo este erro ??
C:\Downloads\Biblioteca\Bd.java:145: warning: [unchecked] unchecked call to addElement(E) as a member of the raw type java.util.Vector
coluna.addElement( info.getColumnName( i ) );
try {
ResultSetMetaData info = rs.getMetaData();
for( int i = 1; i <= info.getColumnCount(); i++ )
coluna.addElement( info.getColumnName( i ) );
do {
linha.addElement( proxLinha( rs, info ) );
} while ( rs.next() );
tabela = new JTable( linha, coluna );
}catch( SQLException sq ){
sq.printStackTrace();
}
