I want to convert a primitive to a string, and I tried:
This fails with the error:
int cannot be dereferenced
Now, I get that primitives are not reference types (ie, not an Object) and so cannot have methods. However, Java 5 introduced autoboxing and unboxing (a la C#... which I never liked in C#, but that's beside the point). So with autoboxing, I would expect the above to convert myInt to an Integer and then call toString() on that.
Furthermore, I believe C# allows such a call, unless I remember incorrectly. Is this just an unfortunate shortcoming of Java's autoboxing/unboxing specification, or is there a good reason for this?
以上就是Why doesn't Java autoboxing extend to method invocations of methods of the autoboxed types?的详细内容，更多请关注web前端其它相关文章！
