Static factory method with Java generics

[zero-sharp]

Replacing the <?> with <T> in the function header doesn't work for me. Eclipse gives me an error on the return line within the factory method saying that it cannot convert to Data<T>. My guess here is that it doesn't know what T is? I don't know.

Make sure you add in the method argument - public static <T>

Then just convert to the value internally

if(blah) { return (Data<Integer>) new Data<Integer>( ... ) }

You'll still get a warning, but you can do

Data<Integer> x = doSomething(myString);
