Answer 1

You need to add a new constraint for the type parameter T.

void someMethod(T y) where T : new()
{
    T x = new T();  
    ...
}

This will only be valid for types with a default constructor however.

The where clause for T is a generic type constraint. In this case, it requires that any type T this method is applied to must have a public parameterless constructor.
