Is it possible to use generic when passing a class for Java function?
I was hoping to do something like this:
Public Stable Class DoStuff {public & lt; T class & lt; List & gt; & Gt; Zero Dust Tolist (T Classname) {System.out.println (className); } Public Zero Testing () {doStuffToList (List.class); // blankets Dustfaltist (Classes); // Compiler Error (unwanted behavior) doStuffToList (integer class); // compiler error (desired behavior)}}
Ideally the list. The square and ArrayList.class line will work fine, but the Integer.class line will cause a compile error. I can use the class
because
public & lt; T increases the list & gt; Void doStuffToList (class clazz)
You're passing after all the class
- parameter type class
,
Actually, & lt; T increases the length of the square .. .. & gt;
means T == class
, because class
is final
. And then you can fix class type parameters to list
- any list
, just list
. Therefore, if you want your example to work, then you will need it:
public & lt; T class increases ?? List & gt; & Gt; Void doStuffToList (T Klase)
But this is not necessary at all.
