This question already has answers here: Closed 11 years ago. Possible Duplicate: Generics constructor with parameter constraint?
This is a follow-up to my previous question but since the previous thread was a long one, i decided to start another thread pertaining to the almost same topic.
Based upon a prior question I had Here. I wanted to join two collections together so that the merged data could be then displayed within a DataGrid of a Silverlight UI.
This may be a very basic question, but it still gets me confused (and Google can\'t h开发者_运维技巧elp) ;-) How can I pass a generic object as a parameter to a function?
In an interview they told me Write the code in the brackets to order the list.They said order but you dont know if the type is going to be int or decimal.
In C#, I can put a type constraint on a generic parameter that requires the generic type to have a default parameterless constructor.Can I do the same in Java?
abstract class Type<K extends Number> { abstract <K> void use1(Type<K&g开发者_JAVA技巧t; k);// Compiler error (Type parameter K is not within its bounds)
To prevent many re-allocations I have something like this in my code: List<T> result = new List<T>(100);
Given this example from the generics tutorial. List<String> list = new ArrayList<>(); list.add(\"A\");
I\'d like to pass a class property (or a getter/setter if need be) reference to a function. For example I have an array of a class with lots of boolean flags.
