Below is a simplified example of what I want to do. In the actual code I catch exceptions to do other things. But essentially I would like to wrap the \'Convert\' class in a generic function, but alas
I am wondering if there is difference (in the aspect of performance, memory saving) to define a list with a default size or specify one.开发者_如何学编程
this question is partially related to my last question. I have a generic class representing a collection of generic objects:
I have a situation that is causing an unchecked cast warning.I know I can use supress warnings, but my instinct tell me there is a way to avoid it by changing how I\'ve coded this snippet.I can\'t, ho
The following code gives a compile error: public void method(List<String> aList) {} public void passEmptyList() {
public class Matrix<TValue, TList extends List<E>> { private TList<TList<TValue>> items;
Using raw type warning occured, how to use par开发者_开发问答ameterized type for List apa=(List)class1.method1(xx);
I want to develope a class in java. The problem is that the constructor doesn\'t work The class is this:
I try to override this method def sum[B >: A](implicit num: Numeric[B]): B = ... in a subclass where type A is already fixed to Int.
There is a base class which has one method of generic type and I am sure that in my derived I will be returning a string. This is my code:
