You could use my ancient Bunch recipe, but if you don’t want to make a “bunch class”, a very simple one already exists in Python — all functions can have arbitrary attributes (including lambda functions). So, the following works: Whether the loss of clarity compared to the venerable Bunch recipe is OK, is a style decision I will of … Read more
One option could be letting your custom class implement the Serializable interface and then you can pass object instances in the intent extra using the putExtra(Serializable..) variant of the Intent#putExtra() method. Pseudocode: Note: Make sure each nested class of your main custom class has implemented Serializable interface to avoid any serialization exceptions. For example:
Yes. In fact Axel Schreiner provides his book “Object-oriented Programming in ANSI-C” for free which covers the subject quite thoroughly.
Most modern browsers have a console in their developer tools, useful for this sort of debugging. Then you will get a nicely mapped out interface of the object/whatever in the console. Check out the console documentation for more details.
Background All Java objects have a toString() method, which is invoked when you try to print the object. This method is defined in the Object class (the superclass of all Java objects). The Object.toString() method returns a fairly ugly looking string, composed of the name of the class, an @ symbol and the hashcode of the object in hexadecimal. The code for this looks like: … Read more
Put anything into an array using Array.push(). Extra information on Arrays Add more than one item at a time Add items to the beginning of an array Add the contents of one array to another Create a new array from the contents of two arrays
How do I determine the size of an object in Python? The answer, “Just use sys.getsizeof“, is not a complete answer. That answer does work for builtin objects directly, but it does not account for what those objects may contain, specifically, what types, such as custom objects, tuples, lists, dicts, and sets contain. They can contain instances each … Read more
You can’t create arrays with a generic component type. Create an array of an explicit type, like Object[], instead. You can then cast this to PCB[] if you want, but I don’t recommend it in most cases. If you want type safety, use a collection like java.util.List<PCB> instead of an array. By the way, if list is already a java.util.List, you should use … Read more
Constructor of public class clients is public but it has a parameter of type ACTInterface that is private (it is nested in a class?). You can’t do that. You need to make ACTInterface at least as accessible as clients.
I have this code And the compiler gave me this Warning for declaring the object slot1 under the private section in class Moveset. Although it gave me the warning but apparently it didnt affect the programme running. Does it actually affect anything? and what am I doing wrong here? Edit: And what is the diifference … Read more
