This code seems to work fine

class Rule<T>
{

    public <T>Rule(T t)
    {

    }
    public <T> void Foo(T t)
    {

    }
 }
  1. Does the method type parameter shadow the class type parameter?
  2. Also when you create an object does it use the type parameter of the class?

example

Rule<String> r = new Rule<String>();

Does this normally apply to the type parameter of the class, in the situation where they do not conflict? I mean when only the class has a type parameter, not the constructor, or does this look for a type parameter in the constructor? If they do conflict how does this change?

SEE DISCUSSION BELOW

if I have a function call

x = <Type Parameter>method(); // this is a syntax error even inside the function or class ; I must place a this before it, why is this, and does everything still hold true. Why don't I need to prefix anything for the constructor call. Shouldn't Oracle fix this.
