How to get equivalent of ResultSetMetaData without ResultSet

StringBuffer queryBuffer=new StringBuffer("SELECT * FROM "+tableName);
PreparedStatement preparedStatement=getConnection("root", "").prepareStatement(queryBuffer.toString());
ResultSet resultSet=preparedStatement.executeQuery();
ResultSetMetaData resultMetaData=resultSet.getMetaData();

from the upper code I got ResultSetMetaData instance and from that I can get any information about table.

but I don’t want to enter select query like above, and want to get information about table.

If you want to get the columns in a table you can do this:

DatabaseMetaData md = connection.getMetaData();
ResultSet rs = dbmd.getColumns(null, null, tableName, "%"); 
while(rs.next()) { 
    String column = rs.getString("COLUMN_NAME"); 
    System.out.println(column); 
}
