generics

[saravanan ragunathan]

is there any reason to avoid primitve types in generics

[Stephan van Hulst]

What do you mean? You can't use primitives as type arguments, if that's what you mean. For instance List<int> is illegal, you should use List<Integer>.

i know that type parameter only accepts reference types (ex:Ineger,Double) but i would like to know that why the developers of java provides this restriction(not to use primitve type);

[Campbell Ritchie]

Because the original implementations for Lists, etc, accepted Objects; that excludes primitives. This was of course in the days before boxing.

In case of primitives compiler already checks the type and no unexpected type mismatch at run time , which cause cast exception.Where as in case of objects object type can be decided at run time as well.
