if you want a parametered constructor the syntax would be:

public class xml_parser {

       private database db;

       public xml_parser (database db) {
                this.db = db;
       }
}

or

public class xml_parser {

       private database db;

       public xml_parser () {
             // constructor;
             db = SOME_DEFAULT_DB_SETTINGS;
       }

       public xml_parser.with_database (database db) {
              // constructor with parameters
                this.db = db;
       }
}


construct is a code block to run on construction not the actual
constructor for the class.
