Like this: public class DerivedClass : BaseClass { public DerivedClass(int derivedParam, String baseParam):base(baseParam) { } } The base keyword here calls the base class constructor that matches the provided parameter overload.
I know this question is rather old but since I originally came here looking for answers, I wanted to share my experience. Yes, you need to implement Parcelable for your Locality class but that is it. If your LocalityList is ONLY a wrapper for ArrayList, then you do not need it. Just use the putParcelableArrayList … Read more
in the addcar method, you try to create a new object (create method) while transfering just a string to it (params[:car] which apparently is set to “Honda”). create expects to get an attributes hash and to stringify it’s keys for the column names. If you have a column named name in your cars table then … Read more
Call it as: php /path/to/script/script.php — ‘id=19&url=http://bkjbezjnkelnkz.com’ Also, modify your PHP script to use parse_str(): parse_str($argv[1]); If the index $_SERVER[‘REMOTE_ADDR’] isn’t set. More advanced handling may need getopt(), but parse_str() is a quick’n’dirty way to get it working.

Also you can use the @Query annotation with the is null syntax : @Query(“[…] where :parameter is … Read more

Generally a parameter is what appears in the definition of the method. An argument is the instance passed to the method during runtime. You can see a description here: http://en.wikipedia.org/wiki/Parameter_(computer_programming)#Parameters_and_arguments
Python passes parameters to functions by value; So for objects, the value passed is a reference to the object, not a new copy of the object. That, along with the following part of the official docs is what helped me understand it better (emphasis mine): Default parameter values are evaluated […] when the function definition … Read more
